Define drift current, diffusion current and P-N junction. The electrical conductivity of a pure silicon at room temperature is $4×10^{(-4)}$mho/m . if the mobility of electron is $0.14m^2/V-S$ and that of hole is $0.04m^2/V-S$.

DRIFT CURRENT :-

Drift current is the electric current, or movement of charge carriers, which is due to the applied electric field, often stated as the electromotive force over a given distance.

DIFFUSION CURRENT:-

Diffusion current is a current in a semiconductor caused by the diffusion of charge carriers. This …
