PROBLEM TO BE SOLVED: To provide a p-type Mg metallic compound (Mg<SB>2</SB>X) excellent in electric conductivity. SOLUTION: In the general formula: Mg<SB>2</SB>X that has an inverse fluorite structure (wherein: X is one or a plurality of group IV elements selected from Si, Ge, and Sn), Li is contained as acceptor dopants. Li has a high solid-solubility limit to Mg<SB>2</SB>X to provide Mg<SB>2</SB>X having high electric conductivity. In addition, Li is less toxic, and thus Mg<SB>2</SB>X can be environmentally-friendly. COPYRIGHT: (C)2010,JPO&INPIT |
