Given below are three statements.
A. At absolute zero, Si acts as a perfect insulator.
B. When p-n junction diode is forward biased, both the thickness of depletion region and the barrier height are increased.
C. Order of energy band gap of C, Si and Ge is
Choose the correct answer from the options given below.
A. At absolute zero, Si acts as a perfect insulator.
B. When p-n junction diode is forward biased, both the thickness of depletion region and the barrier height are increased.
C. Order of energy band gap of C, Si and Ge is
Choose the correct answer from the options given below.
View answer and explanation
Correct option: D
Only A & C are correct
Option D is correct because at absolute zero, silicon acts as a perfect insulator, and the order of energy band gap is correctly given as (E)C > (E)Si > (E)Ge.
