An $\mathrm{n}$ -type silicon resistor has a length $L=150 \mu \mathrm{m}$, width $W=7.5 \mu \mathrm{m}$, and thickness $T=1 \mu \mathrm{m}$. A voltage of $2 \mathrm{~V}$ is applied across the length of the resistor. The donor impurity concentration varies linearly through the thickness of the resistor with $N_{d}=$ $2 \times 10^{16} \mathrm{~cm}^{-3}$ at the top surface and $N_{d}=2 \times 10^{15} \mathrm{~cm}^{-3}$ at the bottom surface. Assume an average carrier mobility of $\mu_{n}=750 \mathrm{~cm}^{2} / \mathrm{V}-\mathrm{s} .(a)$ What is the electric field in the resistor? (b) Determine the average conductivity of the silicon. (c) Calculate the current in the resistor. $(d)$ Determine the current density near the top surface and the current density near the bottom surface.
A p-n junction is formed by combining doped n-type silicon with ρ = 2 (Ωcm) resistance and doped p-type silicon with the same resistance. Calculate the built-in potential barrier of this junction.

Question 3. a) Calculate the resistivity of p-doped silicon at room temperature if the acceptor concentration NA = 1 x 10^17 cm^-3 [6 marks] b) A current of 10 mA flows through a silicon p-n diode at room temperature. Estimate the power dissipation in the diode. [6 marks] N.B. Adopt the following values where appropriate: Boltzmann constant is k = 1.38 x 10^-23 JK^-1. Electron charge is 1.6 x 10^-19 C. Intrinsic carrier concentration, ni, in silicon at 300K is 10^10 cm^-3. Silicon band gap, EG, at 300K is 1.0 eV. Hole mobility, μp, in silicon at 300K is 400 cm^2V^-1s^-1. Electron mobility, μe, in silicon at 300K is 1000 cm^2V^-1s^-1.
