Semiconductor Electronics

Relates the equilibrium concentrations of electrons and holes to the intrinsic carrier concentration at a given temperature.

Gives the total electrical conductivity of a semiconductor in terms of electron and hole densities and their mobilities.

Gives the maximum wavelength of incident photons capable of exciting electron-hole pairs across a bandgap of energy Eg.

Defines the AC or dynamic resistance of a p-n junction diode from the reciprocal slope of its forward V-I characteristic.

Expresses the emitter current as the sum of the base current and the collector current in a bipolar junction transistor.

Relates the common-base current gain alpha and the common-emitter current gain beta of a transistor.
