摘要	To avoid the uncontrollable Mg content in deposited films caused by the easy evaporation of Mg in alloy target, the Mg-2(Sn,Si,Bi) solid solutions films with a tiny of excess Mg metal phase were prepared using a Mg-Sn-Si-Bi alloy target and a high pure Mg target by magnetron sputtering alternately. The phase components, microstructures as well as the thermoelectric properties were systematically investigated. The excess metal Mg phase with a few micron size uniformly distributes in the Mg-2(Sn,Si,Bi) solid solution films and the size of the excess metal Mg phase becomes bigger and bigger and the phase gradually convert a narrow strip shape as Mg target sputtering time increase from 40 to 60 s. It is beneficial to an increase in both Seebeck coefficient and electrical conductivity that a tiny excess metal Mg phase exists in Mg-2(Sn,Si) based films. The Mg-2(Sn,Si) based films containing tiny excess metal Mg phase with an appropriate size posses the highest absolute value of Seebeck coefficient and appropriate electrical conductivity, resulting in the maximum power factor.
