The main reason semiconductor materials are so useful is that the behavior of a semiconductor can be easily manipulated by the addition of impurities, known as doping. Semiconductor conductivity can be controlled by introduction of an electric or magnetic field, by exposure to light or heat, or by mechanical deformation of a doped mono-crystalline grid; thus, semiconductors can make excellent sensors. Current conduction in a semiconductor occurs via mobile or "free"electrons and holes. collectively known as charge carriers. Doping a semiconductor such as silicon with a small amount of impurity atoms, such as phosphorus or boron. greatly increases the number of free electrons or holes within the semiconductor.
It can be make in very small size and the electronics device are small in size that why the semiconductors are used in electronic devices.
The above explains HOW semi conductors work.
The reason for WHY they are used is, what's the alternative?
The only alternative is thermionic valves (tubes).
Tubes fell out of favour for many reasons.
They run hot
Made of glass and delicate,
Consume lots of power
Need high voltages.
Semi conductors are the opposite of all of these.
what is semiconductor state advantages of semiconductor devices over electronic tubes
Semiconductors are commonly used in electronic circuit boards. Semiconductors are the common reasons why capacitors are able to carry out their tasks in a circuit board.
Integrated Circuits with a NE565 frequency can be used in all electronic devices. These semiconductors are lightweight, low cost, and compact making them useful in many modern appliances, phones, and computers.
The other materials other than just silicon used to make semiconductors and other solid state electronic devices are germanium and gallium arsenide.
Semiconductors are usually found in electronic appliances, such as radios and computers. Semiconductors are electrically conductive and are used for power.
Compound semiconductors have very low lifetime of charge carriers and hence they are not used for making Transistors and ICs.Rather it is used for making LEDs and LASER diodes.So the compound semiconductors are called photo-diodes. -M.R
The advantages of electronic devices are many and include making work easier and speeding up delivery of results. As for the disadvantages, the electronic devices can cause great harm if used wrongly and some of them also pose some serious health risks.
at thebeginning of electronic technology the vacuum tube was used in electronic circuit. .but now a days semiconductors are used in electronic circuit
Electronic instruments such as synthesizers are a type of technology used in making music. Recording devices such as tapes and recording software are also used.
its because the gallium emites heat and a negligable photon energy
Type your answer here... nickel
In-numerous electronic devices...........
Carbon is not used in electronic devices because it is difficult to modify its natural properties as opposed to silicon.
Simple electronic circuits are used in simple electronic devices.
Semiconductors are important in many modern electronic devices. Thereare many examples, everday ones are:- silicon is used to make computer chips, gallium nitride, GaN is used in light emitting diodes.
They can be used as a base material for computer chips
Semiconductor raw materials like silicon, germanium, and selenium are the purest substances that you will have a chance to encounter. However the process of making semiconductor devices deliberately contaminate the semiconductor with controlled amounts of various impurities. Other semiconductors like gallium arsenide and the semiconductors used in LEDs are alloys. Other semiconductors like cadmium sulfide and lead sulfide (galena) are compounds.
It is used in transistors and other electronic devices.
Semiconductors may be used to fabricate electronic devices. This is done quite often. Most of the electronic devices they're used for are called "transistors". Often, several transistors are combined in a single small device, called an "integrated circuit". A few examples of where these devices may be found in real life include . . . -- almost every radio in the world -- almost every TV set in the world -- almost every landline telephone in the world -- every TV remote -- every GPS -- every CD/DVD player -- every cellphone and every smartphone in the world.
Wood and plastic
It is used in electronic devices
Silicon and germanium are used in semiconductor devices because they are elemental semiconductors. There are also binary semiconductors (semiconductors composed of two or more elements) that are used in semiconductor devices, some of which are:gallium arsenideboron nitridegallium aluminum indium phosphideindium nitride phosphideindium antimonidesilicon carbidecopper oxidelead sulfide (galena)cadmium selenideetc.Pure carbon in the form of diamond or nanotubes should also be an excellent elemental semiconductor, but the fabrication problems have yet to be resolved before it can be used in semiconductor devices. It has been demonstrated in lab prototype devices already.
Electronic audio and video devices are never used by terrorists for surveillance purposes.
