Some Important Properties of Semiconductors

Why does the resistivity of semiconductor go down with temperature ?
Between the conductor and semiconductor resistivity difference is due to the different density of charge carriers.

Lower resistivity and temperature of semiconductor, because an increase in the number of charge carriers increase temperature quickly, make some change or negative temperature coefficient.


1. Semiconductor in absolute zero as insulators. Raise the temperature, it is a conductor.
2.Because of its special electrical performance, semiconductor by doping modification of semiconductor devices for energy conversion, switch and amplifier.
3.Low power loss.
4.Semiconductor, smaller size and with less weight.
5.Their resistivity is higher than that of a conductor, but less than insulators.
6.The resistance of semiconductor materials decreases with the increase in and vice versa.
