Magneto- seebeck coefficient Bi1-XSbX microwires for thermoelectric applications

Abstract

Due to development of new concepts such as the low- dimensional structures [1] and influence the quantum confinement of change carrier acoustic phonon –boundary scattering for increase figure of merit ZT=2/(T) opened up a completely different strategy for ZT enhancement in one- dimensional structures [1]. We study the thermoelectric properties of Bi1-xSbx in semimetal and semiconductor wires with different diameter in the presence of magnetic field in the temperature range 4.2- 300 K.
