Epitaxial alloys of AlxGa1−xAs:Mg with different types of conductivity

This project employed high-resolution X-ray diffraction, Raman spectroscopy and photoluminescence spectroscopy to investigate the structural, optical and band energy properties of the MOCVD epitaxial heterostructures, AlxGa1−xAs:Mg/GaAs(100), with different levels of magnesium doping. It was shown that the choice of technological conditions used in the preparation of the AlxGa1−xAs:Mg alloy allowed different types of conductivity and it was also possible to achieve significantly different concentrations of the charge carriers in the epitaxial film.
