Assignee: IBARAKI UNIVERSITY
Field: Semiconductors (Electrical engineering)
Classification: CPC H  C | IPC C  H

Claim 6:
7. The method for producing the semiconductor material according to claim 1, wherein the semiconductor material is produced by a direct melting method having the following steps (1) to (5):
(1) a raw material preparation step of preparing a particulate raw material comprising Mg, Sn and Zn;
(2) a raw material filling step of filling a reaction vessel with the raw material prepared in the step (1);
(3) a synthesis step of heating the entire reaction vessel to cause a melting chemical reaction;
(4) a step of cooling a melt produced in the step (3) to deposit a Mg2Sn·Zna single crystal; and
(5) a step of removing the Mg2Sn·Zna single crystal deposited in the step (4) from the reaction vessel.
