ABSTRACT

The lattice constants of AlxGa1−x As epitaxial alloys with various AlAs (x) contents are determined for AlxGa1−xAs/GaAs(100) heterostructures grown by MOC-hydride epitaxy using X-ray diffractometry and an X-ray back-reflection method. An ordered AlGaAs2 (superstructural) phase is found in epitaxial heterostructures with x ≈ 0.50. The lattice constant of this phase is smaller than the lattice constants of an Al0.50Ga0.50As alloy and GaAs single-crystal substrate. More... »
