From the fabrication point of view, why is Si the dominant material in the semiconductor industry? Please list at least 2 reasons.
(a) A silicon pn junction at T = 300 K is reverse biased at VR = 8 V. The doping concentrations are Na = 5 × 1016 cm-3 and Nd = 5 × 1015 cm-3. Draw the band diagram of the pn junction, and determine xn, xp, W, and |Emax|. Please provide the process of derivation.
