AIPMT PRELIMS 2004 Physics Band Theory MCQ Question
Type: MCQ-conceptual-Easy-Class 12
In semiconductors at a room temperature
A
The valence band is completely filled and the conduction band is partially filled
B
The valence band is completely filled
C
The conduction band is completely empty
D
The valence band is partially empty and the conduction band is partially filled
