Abstract: Thermolectric devices could convert temperature gradient into electricity (Seebeck effect) and electric power into temperature gradient across the themoelectric element (Peltier effect). $Bi_2Te_3$ has been widely used as thermoelectric material for more than 40 years, due to the superior thermoelctric characteristics. However, Bi and Te materials are predicted to face supply shortage, giving strong necessity for the development of new thermoelctric materials. Based on the theoretical prediction, nanostructure are expected to give dramatic enhnacement of thermoelectirc characteristics by controlling phonon propagation. Thus, silicon, which had been considered as improper material for thermoelectricity, is now being considered as strong cadidate material for thermoelectricity. This review will focus on the nanotechnology applied research activities in silicon as thermoelectric materials.
