Abstract
As part of research on the influence of selenium as dopant on bismuth telluride, a successful synthesis of single crystal was carried out. Single crystal of p type conductivity, with the given compound formula, Bi2Te2.88Se0.12, was obtained by the Bridgman process. The obtained empirical formula does not deviate from the given compound formula. Single crystal was characterized by Hall Effect system based on the Van der Pauw method. Also, bulk sample was characterized by Seebeck coefficient (S), thermal conductivity (?) and electrical resistivity (?) measurements, as ? function of temperature in the range of 40 - 320?C by ? home made impedance meter. The prepared single crystal has a figure of merit (Z) of 2.16 x 10-3 K-1 at 40?C. Values of ZT are about 1.0 at 27?C for commercialized p and n type of bismuth telluride ingots. T is absolute temperature.
期刊介绍：
Science of Sintering is a unique journal in the field of science and technology of sintering.
Science of Sintering publishes papers on all aspects of theoretical and experimental studies, which can contribute to the better understanding of the behavior of powders and similar materials during consolidation processes. Emphasis is laid on those aspects of the science of materials that are concerned with the thermodynamics, kinetics and mechanism of sintering and related processes. In accordance with the significance of disperse materials for the sintering technology, papers dealing with the question of ultradisperse powders, tribochemical activation and catalysis are also published.
Science of Sintering journal is published four times a year.
Types of contribution: Original research papers, Review articles, Letters to Editor, Book reviews.
