Question

Calculate the emission rate where En=2.5, Nt=10^10cm^-3 and fF (Et)=0.6 .

(a) 15*10^10

(b) 1.5*10^10

(c) 15*10^11

(d) 1.5*10^11

I have been asked this question by my college director while I was bunking the class.

My doubt is from Carrier Life time topic in section Conduction in Semiconductors of Electronic Devices & Circuits

Answer 1

Correct choice is (b) 1.5*10^10

Easy explanation: Ren=En*Nt*(fF (Et))

Substituting the values,

Ren=1.5*10^10.
