Question

Semiconductors obey ohm’s law at only low fields ?

Answer 1

Answer:

This happens because at low temperature, the "p" and "n" type semiconductor resist the flow of electrons through them and then act as resistances, but when the temperature is increased the flow of electrons is Hindered.

Answer 2

Answer:

Because at high temperatures, the resistance increases and they start to behave like insulators which do no follow OHM'S LAW
