Electronics and Communication Engineering (ECE) : Electronic Devices and Circuits - Quiz(MCQ)
Which of the following is false about Fermi-Dirac distribution function f(E) used to understand semiconductors in electronic circuits?
A)
When the temperature decreases f(E) also increases
B)
f(E) doesn’t give the number of energy levels with electrons
C)
f(E) is the probability of finding an electron in an energy level E
D)
f(E) doesn’t give the number of electrons in a given energy level

Correct Answer : Option (A) :   When the temperature decreases f(E) also increases


Explanation : Fermi-Dirac distribution function f(E) is the probability of finding an electron in an energy level E. When temperature increases f(E) also increases.
