Question

What is the forbidden gap voltage for silicon material?

(a) 1.46 V

(b) 1.56 V

(c) 10 V

(d) 1.21 V

I got this question during an interview for a job.

The query is from The Temperature Dependence of P-N Characteristics topic in division Semiconductor-Diode Characteristics of Electronic Devices & Circuits

Answer 1

Correct option is (d) 1.21 V

For explanation I would say: The forbidden gap voltage of a material is numerically equal to forbidden gap energy of the material which is 1.21 joules for silicon so forbidden gap voltage will be 1.21 V.
