Heat transfer plays an important role in science and also affects the variation in the electrical, thermal and physical properties of materials. Heat transfer in semiconductor samples allows us to study the evolution of the temperature, taking account of the conduction and convection in the materials. The measurement in this area requires very sophisticated experiments because it requires considerable affinity. The temperature has an effect on the concentration of ionized impurity, the mobility and the electric conductivity of a semiconductor. Some researchers assume that the electrical conductivity is a constant at higher temperatures than room temperature. At high temperature, the particles are agitated with a thermally high kinetic energy. These particles cede its kinetic energy to neighboring particles having a low temperature for the entire system reaches thermal equilibrium.
