Effective Mg Incorporation in CdMgO Alloy on Quartz Substrate Grown by Plasma-Assisted MBE

The development of CdMgO ternary alloy with a single cubic phase is challenging but meaningful work for technological advancement. In this work, we have grown series Cd1-xMgxO random alloys various Mg concentrations (x = 0, 30, 32, 45, and 55%) on quartz substrate by plasma-assisted molecular beam epitaxy (PA-MBE) technique. structural investigations were performed using the X-ray diffraction (XRD) decreases in average crystallite size lattice parameters observed an increase content alloys. XRD analysis confirms obtained compositions. elemental morphological studies carried out energy dispersive x-ray (EDX) spectroscopy atomic force microscope (AFM) technique, respectively. optical investigation was UV-Vis spectroscopy. bandgaps estimated Tauc relation it varied from 2.34 eV to 3.47 varying zero 55% Urbach increases 112 meV 350 which suggests more disordered localized state incorporation
