Question

(a) What is Hall effect? Find the expression for the Hall coefficient, Hall voltage and mobility. Mention some important applications of Hall effect.

(b) The intrinsic carrier concentration for silicon at room temperature is $10^{10}/\text{cm}^3$. If the mobilities of electrons and holes are $1300\text{ cm}^2/\text{Vs}$ and $450\text{ cm}^2/\text{Vs}$, find the conductivity of silicon at $27^{\circ}\text{C}$?
