半導体

佐藤勝昭研究室の半導体研究

■研究テーマ

化合物半導体の結晶・薄膜成長と光エレクトロニクスへの応用 カルコパイライト構造を持つⅠ-Ⅲ-Ⅵ₂族三元化合物半導体は、ⅡⅥ族、ⅢⅤ族を補完する新しい半導体材料として注目されている。当研究室では、CuAlS₂, CuGaS₂, CuInS₂, CuAlSe₂, CuGaSe₂, CuInSe₂など一連の三元化合物について、結晶成長、薄膜成長を行い、そのキャラクタリゼーションを行ってきた。特に、これらの物質の電気的光学的性質を支配する不純物、欠陥の制御のための基礎データの蓄積を行ってきた。Feを中心とする遷移金属不純物については光スペクトルおよびＥＳＲにより電子状態をほぼ明らかにした。また、希土類元素による発光スペクトルもほぼ明らかにした。 太陽電池をめざして：デバイス化への取り組みとしては、太陽電池への応用を目的としてICBなどイオンの力を利用してCuInSe₂薄膜の低温成長に取り組んだ。 フォトクロミズムをめざして：CuAlS₂とAlの接合においてショットキー特性を得た。この接合に順バイアスを印加した結果、吸収スペクトルの変化を観測した。 カルコパイライト構造をもつII-IV-V₂族単結晶の光ルミネセンスの測定を行った。 新磁性半導体をめざして：CdGeP₂に高濃度にMnを添加することを試みた。

■上記研究テーマの現在までの成果、データなど

化合物半導体の結晶・薄膜成長と光エレクトロニクスへの応用 CuAlS₂中のすべての遷移金属イオンの光学スペクトルとＥＳＲスペクトルを明らかにし、熱処理による着色の変化が、フェルミ準位の移動による遷移金属イオンの価数変化に基づくことを明らかにした。 CuAlS₂中の一連の希土類による発光スペクトルを明らかにした。 CuInSe₂単結晶の赤外線吸収スペクトルからキャリア数を見積もるとともにＥＳＲスペクトルを利用して、熱処理によるフェルミ準位の移動の効果を明らかにした。 CuAlS₂、CuAlSe₂についてCu空孔の電子準位の位置が価電子帯の上それぞれ180meV, 60meVにあることを見いだした。 ICB法によって300ﾟCという低温で、CuInSe₂（いわゆるCIS）の良質の薄膜を成膜しZnO/CdS/CuInSe₂/Moの構造の太陽電池を試作し2%の効率を得た。 CuAlS₂中に添加されたMoによるPLおよびESRスペクトルをはじめて見いだした。 CuAlS₂とAlとの接合において電圧印加による光吸収スペクトルの変化を見いだした。 CdSnP₂単結晶のＰＬスペクトルを測定し、これまでで最も高いエネルギーの発光を発見した。 新希薄磁性半導体CdMnGeP₂を発見。室温で強磁性磁化を示すことを確認した。
