A sample of N-type silicon is at the room temperature. When an electric field with a strength of 1000V /cm is applied to the sample, the hole velocity is measured and found to be 2 × 105 cm/sec.
a. Estimate the thermal equilibrium electron and hole densities, indicating which is the minority carrier. [5 pts]
b. Find the position of EF with respect to Ec and Ev. [10 pts]
c. The sample is used to make an integrated circuit resistor. The width and height of the sample are 10µm and 1.5µm, respectively, and the length of the sample is 20µm. Calculate the resistance of the sa]

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
