From equation (1) is to be found the best dielectric materials, the thermostat must have coefficients of high electric conductivity and Xebec but low heat conductivity. However, it is commonly known that Xebec inverse coefficients are variable with density carrier (Carrier concentration), while the electrical conductivity to density variations correspond to the carrier. On the batchueng and was unable to make the coefficients of electrical conductivity values, Xebec, and rising at the same time. Therefore, it must find a material dimension, for low (Low dimensional) to thermal conditions (K) [7], so that fewer will be able to improve the performance of dielectric material of Thermo. Hotel Hotel Ryde (Bi2Te3) kullu samat is a semiconductor that is effective in changing heat into electricity, because high-ZT at room temperature [8] currently there are several ways to synthesize Bi2Te3 both to prepare the crystals (Bulk) to cube and the film [9] (Thin film), in which a thin film preparation, materials with low dimensions [10] from the studies prepared by r. a. famaek nit Ron sapat Te proper way ngacha foe because it can control the structure and thickness of a thin film and preparing the film, (Large scale) in order to apply actual work [11].
