Semiconductor Electronics

Intrinsic semiconductor is electrically neutral. Extrinsic semiconductor having large number of current carriers would be

A N - type semiconductor is

A p-type semiconductor is

Assertion : In a semiconductor, the conduction electrons have a higher mobility than holes. Reason: The electrons experience fewer collisions.

When an impurity is doped into an intrinsic semiconductor, the conductivity of the semiconductor

Differentiate between intrinsic semiconductors and extrensic semiconductors.

A: When a pure semiconductor is doped with a pentavalent impurity, the number of conduction electrons is increased while the number of holes is decreased R: Some of the holes get recombined with the conduction electrons as the concentration of the conduction electrons is increased.

In an intrinsic (pure) semiconductor, the number of conduction electrons is 7xx10^(19) per cubic meter. Find the total number of current carriers (electrons & holes ) in a same semiconductor of size 1 cm x 1 cm x 1mm.
