Can a semiconductor be made to become a conductor or an insulator?
Yes, a semiconductor can be made to behave as a conductor or an insulator by controlling the amount of impurities added to it. Adding impurities through a process called doping can change the conductivity of the semiconductor material, making it act like a conductor or an insulator.
What are the intrinsic and extrinsic diodes?
Intrinsic diodes are formed by a p-n junction within a single semiconductor material, while extrinsic diodes are formed when impurities are added to a semiconductor material to alter its properties. Intrinsic diodes have natural electrical properties, while extrinsic diodes have controlled electrical properties based on the type and amount of impurities added.
What material is both a conductor and insulator?
wool. are you asking about thermal, electrical, audio. These are different mechanisms.
What are the effects of impurities in boiling and freezing point?
AnswerImpurities tend to increase the boiling point and lower the freezing point.in a way boiling point of salty water > boiling point of fresh waterfreezing properties of salty water < freezing properties of fresh watermelting properties of salty water < melting properties of fresh water.Salt water, contains NaCl, which ionizes into Na and Cl ions. when ions are added to a solvent, such as water, they tend to increase the boiling point and lower the melting point.
What is happening to a substance undergoing thermal energy?
As thermal energy is added to a substance, its temperature increases, causing its molecules to move faster and vibrate more. This can lead to changes in state, such as melting or boiling, depending on the substance and the amount of thermal energy being added.
Diffrentiate n-type and p-type?
When pentavalent impurity is added to pure semiconductor, it is known as N-Type semiconductor. In N-type semiconductor electrons are majority carriers where as holes are minority carriers. impurities such as Arsenic, antimony are added. When trivalent impurity is added to pure semiconductor, it is know as P-type semiconductor. In P-type semiconductor holes are majority carriers whereas electrons are minority carriers. Impurities such as indium, galium are added.

What is doping in conductor?
The process of adding suitable impurities in the intrinsic semiconductor is called doping. The impurity added to the intrinsic semiconductor to increase its conductivity is called dopant. There are some methods of doping in case of a conductor.impurity atoms can be added to the intrinsic semiconductor in different ways discussed below:A very small quantity of impurity atoms is made by diffusing into the high purity molten material such as germanium when the crystal is grown out of melt.Impurity atoms can also be added into the intrinsic semiconductor by heating it in the environment having impurity atoms.Impurity atoms can also be added into the intrinsic semiconductor by bombarding it with the impurity atoms.
What effect do added impurities have on semiconductor conductivity?
It is called as DOPING. Doping is the process in which you add an impurity to a pure semiconductor to increase its conductivity. While doping is done, crystal structure of semiconductor is not disturbed.
What are the intrinsic and extrinsic diodes?
Intrinsic diodes are formed by a p-n junction within a single semiconductor material, while extrinsic diodes are formed when impurities are added to a semiconductor material to alter its properties. Intrinsic diodes have natural electrical properties, while extrinsic diodes have controlled electrical properties based on the type and amount of impurities added.
How many valance electrons does a semiconductor have?
It is not the number of valence electrons that an insulator has that is important. It is the way the valence electrons are "arranged" in the structure of the material that matters. If not all the valence electrons of a substance are "involved" in the structure of the material, then these electrons are said to be free electrons. They move about in the substance, and are free to contribute to electron flow. The metals are examples. In contrast with this, if all the electrons are bound up in a material, they are not free to support current flow, and the material is said to be an insulator. Said another way, if the valence electrons in a material are in a Fermi energy level that overlaps the conduction band for that material, the material is a conductor. In an insulator, the valence electrons are all in Fermi energy levels that are below the conduction band for that material, and it is an insulator. Applying a voltage to an insulator will not "lift" the valence electrons up into the conduction band to allow them to support current flow.
What is the difference between donor and acceptor impurities?
Donor impurities are atoms added to a semiconductor that have extra valence electrons, which can easily be donated to the conduction band, enhancing conductivity; examples include phosphorus in silicon. In contrast, acceptor impurities have fewer valence electrons, creating "holes" in the lattice that can accept electrons, also increasing conductivity; an example is boron in silicon. Essentially, donor impurities contribute free electrons, while acceptor impurities create holes that can facilitate electron movement.
Why is the concentration of SODIUM CARBONATE SOLUTION ADDED TO THE DISTILLATE?
Sodium carbonate solution is added to the distillate to neutralize any remaining acidic impurities in the distillate after distillation. This helps to ensure that the distillate is at a neutral pH, making it suitable for further processing or analysis.

Which impurities are added to pure gold for making jewelry?
Copper and silver are commonly added to pure gold to create alloys that are suitable for making jewelry. These impurities help enhance the durability and strength of the gold, as pure gold is too soft to be used on its own for most jewelry designs.
Does semiconductor lasers and laser diodes are similar?
Semiconductor lasers are made with laser diodes, with added circuitry to measure and regulate the diode current/output.
What is meant by intrinsic silicon?
Intrinsic silicon is pure silicon with no intentional impurities added. It has a balanced number of positive and negative charge carriers, making it an electrical insulator at room temperature. Intrinsic silicon is the base material used in semiconductor device fabrication.
