Abstract

The knowledge of the temperature reached in the irradiation region of a strongly absorbing semiconductor is important for laser annealing. Due to the small volume of the heated material, it is difficult to obtain precise temperature information; one must study the energy spectrum of the heated region, which may differ considerably from that of blackbody radiation.
