(特許文献1) 特開平10−313096号公報
図10は、図8に示した半導体基板100の特性を確認するべく作製した半導体基板100の一例を示す。図10に示す半導体基板100は、図8に示した半導体基板100と同等の構造を有する。図11は、作製した半導体基板100の特性と比較するべく作製したp型p−HHMT単体の比較サンプルの構造を示す。本実験においては、半導体基板100の第2チャネル層408におけるシートキャリア濃度および移動度が、p型p−HHMT単体の比較サンプルと同等の特性を有するか否かを判定する。以下、実験に用いた半導体基板100の作製手順を説明する。
実験例1で作製した半導体基板100において、コンタクト層416から正孔供給層404までの層をエッチングにより除去して、バッファ層402の表面を露出した。図13は、バッファ層402に設けた電極450および電極452の形状を示す。電極450および電極452は、バッファ層402の表面に、順次AuGe、Ni、Auからなる層をそれぞれ10nm、10nm、100nmの厚みになるように蒸着して形成した金属電極である。
