Ga and In atoms were used as pre-evaporating materials. GaAs layers were grown by conventional molecular beam method under various V/III ratios. By Ga pre-evaporation method, the domain of rotational twin increased. In contrast, the twin domain decreased by In pre-evaporation method. We found that the In pre-evaporation method was effective at V/III ratios between 30 and 100.}, pages = {19--22}, title = {Si(111)表面へのIII族供給によるGaAs薄膜中の回転双晶軽減}, volume = {42}, year = {2013}, yomi = {イトウ, ダイキ and タチカケ, ヒロアキ and スズキ, ヒデトシ and フクヤマ, アツヒコ and イカリ, テツオ and イトウ, ダイキ} }
