Switching speed of P+ junction depends on.
(a) Mobility of minority carriers in P junction
(b) Life time of minority carriers in P junction
(c) Mobility of majority carriers in N junction
(d) Life time of minority carriers in N junction
This question was posed to me in an interview for internship.
This key question is from PN Diode Switching Times in portion Semiconductor-Diode Characteristics of Electronic Devices & Circuits
