Three types of bands are shown in the figures given below showing the position of the valence band and conductions band. The figures A,B and C represent
A B C
A
Non – metal Metal Semiconductor
B
Semiconductor Insulator Conductor
C
Metal Insulator Insulator Semiconductor
D
Insulator Conductor Semiconductor
Answer
Metal Insulator Insulator Semiconductor
Explanation
Solution
In conductors there is no gap or overlapping between valence band and conductions band. The insulators have a large gap while semiconductor have a small energy gap.
