WebIn the solid-state physics of semiconductors, carrier generation and carrier recombination are processes by which mobile charge carriers (electrons and electron holes) are created and eliminated.Carrier generation and recombination processes are fundamental to the operation of many optoelectronic semiconductor devices, such as photodiodes, light … WebProblem 1: pn Diode Charge Control Model. Given: junction area A = 100 m2; minority-carrier lifetimes (n = 10-6 s (p side) and (p = 10-7 s (n side); T = 300K. Since the minority carrier concentrations (np and pn) are enhanced within the quasi-neutral regions, the diode is forward biased. The majority carrier concentrations (pp and nn) are not ...
