Question

explain effect of temperature on metal and semiconductor ans​

Answer 1

Answer:

Semiconductors: With increase in temperature, the conductivity of the semi-conductor material increases. ... So with decrease in temperature, the thermal effect is nullified and the electrons can flow smoothly without hindrance and thus conductivity increases.

Explanation:

Semiconductors: With increase in temperature, the conductivity of the semi-conductor material increases. AND METAL: Restivity is affected by temperature - for most materials the resistivity increases with temperature. An exception is semiconductors (e.g. silicon) in which the resistivity decreases with temperature.
