Question

Why is temperature co efficient negative for semi conductors? Apt answer gets brainliest and 20 thanks

Answer 1

An increase in the temperature of a semiconducting material results in an increase in charge-carrier concentration. ... The increasing conductivity causes the resistivity of the semiconductor material to decrease with the rise in temperature, resulting in a negative temperature coefficient of resistance.”
