The kind of material used in a device depends on its requirements and functions. Semiconductors are used where we need moderate conductivity, conductors are used where we need very high conductivity.
Junction diodes(a semiconductor device) allows electricity to pass in one direction and can be used as rectifier. Conductors can't do this. Transistors and LED are other applications of semiconductor.
Note that generally devices are made of both conductors and semiconductors.

Is galleon used as electronic semiconductor?
Galleon is not typically used as an electronic semiconductor. Instead, the term "galleon" generally refers to a type of sailing ship from the 16th to 18th centuries. In the context of electronics, materials like silicon, gallium arsenide, and germanium are commonly used as semiconductors. If you're referring to gallium, it is indeed used in some semiconductor applications, particularly in compound semiconductors.
What is an intrinsic semiconductor and what is an extrinsic semiconductor?
intrinsic semiconductor is an un-doped semiconductor, in which there is no impurities added where as extrinsic semiconductor is a doped semiconductor, which has impurities in it. Doping is a process, involving adding dopant atoms to the intrinsic semiconductor, there by gives different electrical characteristics
How does a Shockley diode work?
A Shockley diode uses a metal-semiconductor junction instead of a p-n semiconductor-semiconductor junction. This results in a device with a much lower forward bias voltage drop and much faster switching times.
What is mean't by Reverse voltage?
Reverse voltage is voltage is applied in reverse. Instead of the positive voltage going into the anode lead of a component, it goes into the cathode lead of the component.
What is a aerial bundle conductor?
In science and engineering, conductors are materials with low resistivity, this due to the presence of mobile charged particles within the material. In metallic conductors, such as copper or aluminum, the movable charged particles are present because atoms have loosely held valence electrons. See electrical conduction. All conductors contain electric charges which will move when an electric potential difference (measured in volts) is applied across separate points on the material. This flow of charge (measured in amperes) is what is meant by electric current. In most materials, the rate of current is proportional to the voltage (Ohm's law,) provided the temperature remains constant and the material remains in the same shape and state. The ratio between the voltage and the current is called the resistance(measured in ohms) of the object between the points where the voltage was applied. The resistance across a standard mass (and shape) of a material at a given temperature is called the resistivity of the material. The inverse of resistance and resistivity is conductance and conductivity. Most familiar conductors are metallic. Copper is the most common material for electrical wiring, and gold for high-quality surface-to-surface contacts. However, there are also many non-metallic conductors, including graphite, solutions of salts, and all plasmas. See electrical conduction for more information on the physical mechanism for charge flow in materials. Non-conducting materials lack mobile charges, and so resist the flow of electric current, generating heat. In fact, all materials offer some resistance and warm up when a current flows. Thus, proper design of an electrical conductor takes into account the temperature that the conductor needs to be able to endure without damage, as well as the quantity of electrical current. The motion of charges also creates an electromagnetic field around the conductor that exerts a mechanical radial squeezing force on the conductor. A conductor of a given material and volume (length x cross-sectional area) has no real limit to the current it can carry without being destroyed as long as the heat generated by the resistive loss is removed and the conductor can withstand the radial forces. This effect is especially critical in printed circuits, where conductors are relatively small and close together, and inside an enclosure: the heat produced, if not properly removed, can cause fusing (melting) of the tracks. Since all conductors have some resistance, and all insulators will carry some current, there is no theoretical dividing line between conductors and insulators. However, there is a large gap between the conductance of materials that will carry a useful current at working voltages and those that will carry a negligible current for the purpose in hand, so the categories of insulator and conductor do have practical utility. Thermal and electrical conductivity often go together (for instance, most metals are both electrical and thermal conductors). However, some materials are practical electrical conductors without being a good thermal conductor In science and engineering, conductors are materials with low resistivity, this due to the presence of mobile charged particles within the material.

Why do you use semiconductor why not conductors and insulators by changing their properties?
We use semiconductors instead of conductors and insulators by changing their properties because the properties of a semiconductor lies between that of a good insulator ant that of a good conductor. Any of the materials obtained depends on the level of doping.
Why water cannot be used instead of oil to dip the semiconductor specimen?
Water can react with the semiconductor materials, such as silicon, and potentially corrode or degrade them. Oil is non-reactive with semiconductor materials, making it a better choice for dipping semiconductor specimens for protection during storage and handling.
What is a metalloid called if it conducts electricity better than non-metals but not as well as metals?
A metalloid that conducts electricity better than non-metals but not as well as metals is called a semiconductor. Semiconductors have electrical conductivity between that of metals and insulators, making them important materials for electronic devices.
Why semiconductor is used instead of a conductor in solar cells?
Semiconductors are used in solar cells because they have properties that allow for efficient conversion of sunlight into electricity. This is achieved through the creation of an electric field within the semiconductor material, which helps separate the generated electrons and holes, leading to the flow of electric current. Conductors do not possess these properties and are not suitable for converting sunlight into electricity in the same way.
Why Zinc oxide is a semiconductor?
A substance is classified as a good/bad/semi conductor based upon the energy gap (band gap) in between the valence bands and conduction bands (which are nothing but the collection of molecular orbital energy levels). for ZnO the band gap is ~3.4eV (electron volts). this value is more than for a conductor (like most of the metals Cu, Zn, Ag, Au etc) and less than bad conductors (Wood, Paper etc). so ZnO is a semi conductor. these type of materials can be played with to behave as a good or bad conductor.
Is keychain conductor or insilator?
A keychain is not a conductor or insulator as it is typically made of materials like metal or plastic that do not conduct or insulate electricity well. Instead, keychains are primarily used for organizing and carrying keys.
Explain what happens when a long straight conductor is moved through a uniform magnetic field at a constant velocity Assuming that the conductor moves perpendicularly to the field?
Interesting question. Because Fleming's right hand rule tells us that a conductor carrying a current perpedicular to a magnetic field will move in a particular direction we know that movement, current and magnetic field are related. So if we take the current away and instead force the conductor to move as described then we would observe a current in the wire. However, you have not said that your conductor is connected in a circuit - in which case the charge carriers in the conductor will tend to one side like a bar magnet.AnswerThe original answer is incorrect. A voltage would be induced into the conductor. No current would flow unless the conductor forms a continuous circuit.
What is a schottky transister?
A very high speed bipolar junction transistor having a metal-semiconductor emitter base junction instead of a semiconductor-semiconductor emitter base junction.
Does the amount of heat produced depend on the material of the conductor?
Yes, resistance in a conductor causes energy losses due to heat. Metals such as Gold and Platinum have very low resistance but they are very expensive so Copper and Aluminium are used instead which are much more affordable but have higher resistance.
Is plastic a convector?
Plastic is generally considered a poor conductor of heat and electricity, meaning it does not effectively transfer thermal energy or electrical current. Instead, it acts as an insulator, making it suitable for applications where heat or electrical insulation is needed. Some specialized plastics can have enhanced conductive properties if modified or combined with conductive materials, but in its standard form, plastic is not a good conductor.
Can a resistance be used in the circuit instead of diode?
No. A resister is not a replacement component for a diode. A resister is passive and allows current to flow through in in both directions. A diode is a single semiconductor junction that only allow current to flow in one direction.
Is galleon used as electronic semiconductor?
Galleon is not typically used as an electronic semiconductor. Instead, the term "galleon" generally refers to a type of sailing ship from the 16th to 18th centuries.
