The maximum energy upto which the electron occupies in a semiconductor at an absolute zero temperature is called as ___________

A semiconductor has ………… temperature coefficient of resistance.Select one:a. Negativeb. Zeroc. Infinited. Positive

As the temperature of a semiconductor increases its(1 Point)Conductivity increasesResistivity increasesAtomic number decreasesTemperature co-efficient becomes zero

In an intrinsic semiconductor, the Fermi levelSelect one:a. May be anywhere in the forbidden energy gapb. Is near the valence band.c. Is near the conduction bandd. Lies at the centre of forbidden energy gap

An electron is in a one-dimensional potential well of width 0.79 nm. The energy (to two decimal places and in units of eV) of this electron in its first excited state is
