Size and temperature effects on the Seebeck coefficient of thin bismuth films
V. Damodara Das,N. Soundararajan +1 more
TL;DR: The electrical resistivity and the Seebeck coefficient of thermally evaporated thin bismuth films of thicknesses from 300 to 1900 A\r{} have been measured and the latter is negative and its magnitude is found to increase initially with increasing temperature, reach a maximum, and then decrease with a further rise in temperature.
Journal ArticleDOI
Electrical conductivity and thermoelectric power of amorphous Sb2Te3 thin films and amorphous-crystalline transition
TL;DR: In this paper, the results of electrical conductivity and thermoelectric studies on antimony telluride in the thin film state were reported, where vacuum-deposited on to clean glass substrates with thickness between 50 and 200 nm and studied in the temperature interval 300 to 470 K. This is attributed to an amorphous to crystalline transition, which is confirmed by X-ray diffractogram and electron diffraction patterns.

Thermoelectric power and electrical resistivity of crystalline antimony telluride (Sb2Te3) thin films: Temperature and size effects
V. Damodara Das,N. Soundararajan +1 more
TL;DR: In this article, the size dependence of thermoelectric power and electrical resistivity have been analyzed by the effective mean free path model of size effect, and it is found that both the thermoeellectric powers and the electrical resistivities are linear functions of the reciprocal of thickness of the films.
Journal ArticleDOI
Thermoelectric power of tellurium thin films and its thickness and temperature dependence
TL;DR: In this article, it was shown that thermoelectric power is independent of temperature and is also independent of thickness, over the range of temperatures and thicknesses investigated, and the results were discussed on the basis of size effect and temperature effect theories.
