| Outline of Final Research Achievements |
It was investigated the relation bewteen undercooling degree and crystal growth of Si and compound semiconductor single crystal formation by using short drop tube procee. 3dTM (Fe,Ni,Co,Mn) and RE (Nd, Gd) elements added Si was prepared from 0 to 10% contained fine particles was analyzed microstructure. Consequently,by adding a small amount of 3dTM and RE elements, and containerless solidifies in the high undercooling state,completely different microstructures were observed with pure Si. Furthermore,it was shown to produce a silicide on the surface of the fine particles and the grain boundary. In addition,the effectiveness of the short drop process for InSb and GaSb binary and Fe added ternary single crystal fine particles formation and continuously to enable the band gap control (InGa) Sb ternary mixed crystal semiconductor particle formation has been clarified.
