Composition dependent thermoelectric Power (α) of Ag-Te thin films as a function of temperature and thickness.
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 9
Abstract
Silver –Tellurium thin films of varying compositions and of fixed thicknesses have been formed on glass substrates in a vacuum of the order of 10 –5 torr. The films were annealed at constant temperature for 6 to 8 hours, after annealing the temperature dependent thermoelectric power (α) of the films has been evaluated. The phase change of Ag-Te thin films was found to be composition dependent at room temperature and independent on thickness. The thermoelectric power (α ) for both p-type and n-type materials for a fixed thickness have been carried out with a constant temperature difference of 10 0K employing three temperature method.
