Claim:
1. A method for manufacturing a p-type semiconductor composed of magnesium, silicon, tin, and germanium comprising: mixing magnesium, silicon, tin, and germanium as raw materials, obtaining, by liquid-solid reaction, a solid solution of the magnesium, silicon, tin, and germanium mixture represented by the following general chemical formula: Mg sintering the obtained mixture to produce a p-type semiconductor, the p-type semiconductor represented by the following general chemical formula: Mg X is in the range of 0.00<X≦0.25, and Z satisfies the relationship of −1.00X+0.40≧Z≧−2.00X+0.10, and Z>0.00, and Y is in the range of 0.60≦Y≦0.95, and Z satisfies either of the following relationships: −1.00Y+1.00≧Z≧−1.00Y+0.75, where 0.60≦Y≦0.90 and Z>0.00, and −2.00Y+1.90≧Z≧−1.00Y+0.75, where 0.90≦Y≦0.95 and Z>0.00.
