2. III-V and II-VI semiconductors are known as ____________ semiconductors.
3. The drift velocity of a charge carrier is the product of its _________ and the ___________ it experiences.
4. In a p-type semiconductor, the minority carriers are ___________.
5. The units of capacitance are __________.
6. A ______________ material is one that is electrically insulating and which has, or can be made to exhibit, an electric dipole.
7. A ______________ bias is applied to a pn junction so that little current flows. Majority carrier electrons and holes flow away from the junction.
8. Acceptor saturation occurs when the electrons from all of the extrinsic holes in a _____-type semiconductor have been formed in the _________ band.
Explanation / Answer
Ans 1 : hexagonal (wurtzite)
The compound gallium nitride exists as hexagonal lattice . Though a cubic lattice also exists , but it is not much of a researched material. It has its variety of application in amplifiers , oscillators etc.
