Question

semiconductor obey ohms law only at low field why?

Answer 1

because if we apply HIGH electric field heat energy will be induced due to resistance and ohm law vaild when temperature constant so semiconductor obey ohm law at low field

Answer 2

The semiconductors at low electrical field acts as normal resistances and hence follow the Ohm's law like the way of resistances follows.

Explanation:

• 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.
• The temperature of the diode and the resistance will be altered and the working of semiconductor will be affected and can be damaged too.
