Coulometric titration of gallium in gallium arsenide.
BUNSEKI KAGAKU, 1990 電量滴定法によりヒ化ガリウム中のガリウムの定量を行った.分析方法としては,ガリウムに対して過剰のEDTAを加えてキレート生成させて,過剰分を電解発生させた銅(II)イオンで逆滴定するという手法を採った.そこでEDTAの純度分析を行ったところ,銅(II)イオンによる滴定条件において基礎液の濃度とpH調節が重要であった.又滴定終点は,ポテンショスタットで電位規制した作用電極上での銅(II)イオンの還元電流を利用して決定した.EDTAの純度分析の結果は99.749%となり,この値に基づいて高純度ガリウムの定量,更にヒ化ガリウム中のガリウムの定量を行った.ヒ化ガリウムを試料とした場合には共存するヒ素(V)の影響が大きいことから,ヒ素(III)への還元操作を加えた ...

Graphene on gallium arsenide: Engineering the visibility [PDF]
Applied Physics Letters, 2009 Graphene consists of single or few layers of crystalline ordered carbon atoms. Its visibility on oxidized silicon (Si/SiO2) enabled its discovery and spawned numerous studies of its unique electronic properties. The combination of graphene with the equally unique electronic material gallium arsenide (GaAs) has up to now lacked such easy visibility ...
