Effect of Zn doping on improving crystal quality and thermoelectric properties of borosilicides.

Abstract

Transition-metal (Mo, Mn, Fe, Rh, Ti, Cu, Zn) doping was carried out on the borosilicide compound REB(44)Si(2) (RE = rare earth). REB(44)Si(2) compounds exhibit Seebeck coefficients greater than 200 microV K(-1) at high temperatures and unlike most compounds, the figure of merit shows a steep increase at T > 1000 K making them promising high-temperature… (More)
