A piece of intrinsic (pure) silicon at room temperature has, at any instant, a number of conduction-band (free) electrons bthat are unattached to any atom and are essentially drifting randomly throughout the material. Also, and equal number of holes are created in the valence band when these electrons jump into the conductance band.
What else can I help you with?
Why do you use semiconductors while the conductors are in use?
Semiconductors might sound somewhat 'inferior' in comparison to 'conductors', but they are - due to their unique properties - indispensable in modern electronics. Semiconductors, generally, make it easily possible to control the direction and flow of electric current which is the basis of most modern electronic device.
What is the advantage of organic semiconductors over a semiconductors?
Organic semiconductors are inexpensive hence easy to fabricate device out of them, they can be modulated in various desirable way like in electronic properties of band gap, can be made transparent which is good for Optical electrodes, flexible. Because of these modulation they are finding their application in wide varieties of area. Of course they are very attractive choice for researchers now a days.
Is iron an example for a semiconductor?
No. Iron is a conductor, as are the majority of other metals. Semiconductors would be like silicon and graphite in the form or carbon nanotubes. Metals = ConductorsSome metalloids=semiconductors.
What are minority carriers charge carriers?
Minority carriers are charge carriers in a semiconductor that are present in smaller quantities compared to majority carriers. In n-type semiconductors, minority carriers are holes, while in p-type semiconductors, they are electrons. These carriers play a crucial role in determining the electrical properties of semiconductors, particularly in processes like recombination and conduction. Their behavior is essential for the operation of devices such as diodes and transistors.
What are examples of semiconductors?
Germenium and silicon are the examples of Semiconductors.

What properties are desirable?
The properties that are desirable in a computer will depend on what you need it for. If you want it to play games, you will want a good video and audio card.
Do compound semiconductors behave as intrinsic semiconductors?
No, compound semiconductors do not behave as intrinsic semiconductors because they have different band structures due to the combination of different elements. Compound semiconductors have unique electrical properties that make them suitable for specific applications that require different performance characteristics compared to intrinsic semiconductors.

What do metalloid and semiconductor have in common?
Metalloids and semiconductors have similar properties due to their intermediate characteristics between metals and nonmetals. Both can conduct electricity to some extent, with metalloids having properties of both conductors and insulators, while semiconductors are used in electronic devices due to their ability to control the flow of current.
What is the significance of the work function of semiconductors in determining their electronic properties and behavior?
The work function of semiconductors is important because it determines how easily electrons can move within the material. A lower work function means electrons can move more freely, leading to better conductivity. This influences the electronic properties and behavior of semiconductors, affecting their performance in electronic devices.
What properties of semiconductors make them useful in electric devices?
They can be used as a base material for computer chips
What two technologies are used to manufacturer microchips?
Microchips are generally manufactured using photo-lithography to control the placement of semiconductors. The semiconductors are made by doping the metal to alter its electrical properties
