QAIPMT-2003-Ch-2660: NEET 2004 Physics - Class 12 AIPMT-2003-Ch-2660 Solution: In semiconductors at a room temperature
In semiconductors at a room temperature
Multiple Choice Options
- A the valence band is partially empty and the conduction band is partially filled
- B the valence band is completely filled and the conduction band is partially filled
- C the valence band is completely filled
- D the conduction band is completely empty
Step-by-Step Verified Solution
In semiconductors at room temperature the
electrons get enough energy so that they are able to
over come the forbidden gap. Thus at room
temperature the valence band is partially empty and
conduction band is partially filled. Conduction band
in semiconductor is completely empty only at 0 K.
