Question

Energy gas between valence band and conduction band of a semiconductor is :

• A. zero
• B. infinite
• C. 1 eV
• D. 10 eV

Answer 1

Answer: (C)

1 eV

Answer 2

For conduction band difference should be $> 5\, eV$.
Different value for different semiconductors are given in figure near about $1\, eV$
