Pros And Cons Of Semiconductor Devices

In a semiconductor,

Introduction to semiconductors and semiconductors devices

Element commonly used in modern semiconductor devices is

Assertion: Thickness of depletion layer is fixed in all semiconductor devices. Reason: No free charge carriers are available in deplection layer.

Assertion : The thickness of depletion layer is fixed in all semiconductor devices. Reason: Free charge carriers are available in depletion layer.

I-V characteristics of four semiconductor devices are in graphs (i) ,(ii) (iii) and (iv) the characteristics of zener diode and solar cell are show correctly in :

Statement-I : Germanium is preferred over silicon for making semiconductor devices Statement-II : Energy gap for Ge is more than that of SI

Assertion: In vacuum tubes (vales), vacuum is necessary for the movement of electrons between electrods otherwise electrons collide with air and loss their energy. Reason: In semiconductor devices, external heating or vacuum is not required.
