[SOLVED] VE320- Quiz 4

Description

1. From the fabrication point of view, why is Si the dominant material in the semiconductor industry? Please list at least 2 reasons.

2. (a) A silicon pn junction at T = 300 K is reverse biased at V_R = 8 V. The doping concentrations are N_a = 5 × 10¹⁶ cm^-3 and N_d = 5 × 10¹⁵ cm^-3. Draw the band diagram of the pn junction, and determine x_n, x_p, W, and |E_max|. Please provide the process of derivation.
