Actually Welcome to the Concept of the Resistance.

The Relationship of resistance and resistivity is given as,

R = rho(l/a)

here, rho = the resistivity of the material.

Since , the semi - conductor have a alter nature at high temperature.

Hence, SEMI - CONDUCTORS have less resistivity with the increase in the temperature.
