[13a-2T-7] Thermoelectric properties of higher manganese silicide partially substituting small amount of Ta for Mn
Keywords:Thermoelectrics,Electronic structure,Band calculation
The lattice thermal conductivity in in higher manganese silicide(HMS) was reduced by substituting ubiqutously heavier element Ta for Mn without badly affecting electron transport properties. So, the ZT of Ta doped HMS is larger than that of heavy element free HMS.
