Silver Chalcogenides

Silver chalcogenides have received much attention in potential thermoelectric materials research because of high carrier mobility and low effective mass. Among them, in Ag2Te, it was reported that the phase transition from monoclinic to cubic phase occurs at relatively low temperatures, so that extensive research for effective application using this material has been aroused. In this work, we investigated how 1-dimensional nanostructure affects the thermoelectric properties through as-synthesized single crystalline Ag2Te nanowires. Adopting well-defined thermoelectric MEMS device structure and transferring an individual Ag2Te nanowire, we measure electrical resistance and Seebeck coefficient as a function of temperature. When the phase changes from monoclinic to cubic, the resistance increases, while absolute Seebeck coefficient value decreases. These results are compared with previous reports for Ag2Te bulk and film, suggesting the increased density of states of the carriers due to nanowire structure.

Abstract (Perovskites Photovoltaic) PPV cells are the hottest topics in solar cells in the recent years, because of the remarkable structural and electronic properties and hence rapid progress in material science. The Challenge associated with high-mobility BaSnO3 films is to grow. It shows high carrier mobility and UV-visible transparency has been attracting more and more attention as a very promising component for the next generation opto-electronics. Here, we demonstrate a Structural and Electronics properties (Sp and Ep), To characterize this compound theoretical calculation have been performed by using first principal method and the results show BaSnO3 is conductor at 0eV i.e. room temperature and gaining energy make more conduction transferring more electrons from conduction to valence bands. BaSnO3 shows 5.78e.v maximum for the conduction. We have studied this compound in ideal cubic phase. At 0° Kelvin calculation are performed to get different properties. No experimental studies have been done on this compound. And it was difficult to accumulate its experimental data. WC-GGA is used for the study of structural properties of BaSnO3. This Correlation potential can also be used for the calculation of the various perovskite. Depending on the cubic (ABX3) composition, perovskites exhibit a wide range of structural and electronic properties, which are optimized for different applications.
