Question

Which of the following term isn’t a part of the total current density in a semiconductor?

(a) Temperature

(b) µ

(c) e

(d) E

This question was posed to me during an interview for a job.

My doubt is from Diffusion in section Conduction in Semiconductors of Electronic Devices & Circuits

Answer 1

The correct choice is (a) Temperature

To elaborate: J=enµE+epµE+eDdn/dx-eDdp/dx

So, temperature isn’t a part of the equation.
