Research Abstract

強磁性半導体(Zn,Cr)Teにおける荷電性の不純物ドーピングによる磁性の変化を調べた。(Zn,Cr)Teにアクセプター性不純物である窒素をドープすると強磁性が抑制されるが、分子線エピタキシー法により成長した窒素ドープ(Zn,Cr)Teにおいて、窒素のドーピング量と強磁性特性との定量的関係より、窒素ドーピングに伴うCrイオンの価数変化と強磁性抑制との関係を解析し、この系の強磁性メカニズムについての考察を行った。さらに、(Zn,Cr)Te層と非磁性半導体である窒素ドープ(Zn,Mg)Te層からなるρ型の変調ドープヘテロ構造を作製し、ヘテロ界面に生成される2次元正孔により(Zn,Cr)Te層の強磁性が抑制されることを明らかにした。
