Semiconductor E...

In an intrinsic semiconductor, the number of electrons in the conduction band is ________ the number of holes in the valence band.

The energy gap in glass at room temperature is

Materials which allow only larger currents to flow through them are

In an intrinsic semiconductor, if $$N_e$$ is the number of electrons in the conduction band and $$N_p$$ is the number of holes in the valence band then.

A pure semiconductor at absolute zero has

The symbolic representation of four logic gates are given below :
The logic symbols for OR, NOT and NAND gates are respectively :

In n-type of semiconductor, majority carries are

Number of electrons in the valence shell of a semiconductor is

In an insulator, the forbidden energy gap between the valence band and conduction band is of the order of

The gate for which output is high, if at least one input is low is
