Молекулярно-лучевая эпитаксия GaSb на вицинальных подложках Si(001): влияние условий зарождения слоев на их структурные и оптические свойства

GaSb films were grown by molecular beam epitaxy on vicinal Si(001) substrates with miscut angles of 6° to the (111) plane. Films were formed on AlSb(001)/Al/As/Si, AlSb(00-1)/Al/As/Si, GaSb(00-1)/Ga/P/Si and GaSb(001)/P/Ga/Si transition layers. The influence of orientation, composition, and formation conditions of transition layers on the crystal perfection and optical properties of GaSb films was studied. The GaSb film grown on the GaSb(00-1)/Ga/P/Si(001) transition layer has the best structural and optical properties.
