Question

Pure semiconductor material at temperature 0k is

Answer 1

At Absolute zero temperature (0 Kelvin) the electrons in the valence band of semiconductors do not possess enough thermal energy to overcome forbidden energy gap. So semiconductors stop conducting and behave as insulators.

Answer 2

Semiconductors at 0 kelvin lose their ability to conduct electricity and behave as insulators.

• At 0 temperature the valence bond is occupied by all of its electrons and hence semiconductors at 0 kelvin lose their ability to conduct electricity and behave as insulators.
• The forbidden energy gap also gets very large when the temperature is 0 kelvin.
• At an absolute temperature of 0 k, not only does the forbidden energy gap increase but also the bandgap of the semiconductor gets in the order of 3ev.
