Effect of Surface Polishing on the Thermoelectric Power of InSb Crystals
Abstract
Abstract. The effects of surface polishing on the thermoelectric properties of InSb crystals have been studied. For this purpose, we grew high -quality InSb crystals. This crystal has the real surface and we call it “as prepared”. Also, a cleaned surface was obtained by polishing processes. A detailed work for comparing the measured thermoelectric in the pre-mentioned two cases was done. This included the study of the crystals by means of X-ray diffraction and the scanning electron microscopy images (SEM). The goal is to find out the influence of the surface treatment on the values of thermoelectric power (α). This was done over a wide range of temperatures (200-500K). Unique-results were obtained for the first time first time, and were represented using useful histograms.
