[15p-A403-6] Effect of P-doping on the thermoelectric properties of Mg2Si crystals

〇Daisuke Miyago1, Haruhiko Udono1 (1.Ibaraki Univ.)

Keywords:semiconductor, thermoelectric properties

Magnesium silicide, which is abundant in resources and suitable for mass production, is expected to be an alternative thermoelectric material for practical use. In this study, phosphorus was added as an impurity to single-crystal magnesium silicide, and its effects on thermoelectric properties were systematically investigated.
