Characterization of impurety diffusion induced disordering in GaAs/AlGaAs multiquantum well structures, grown by molecular beam epitaxy, has been carried out by scanning electron microscopy. ...
We report, for the first time, a direct relationship between the composition fluctuation on the ternary layer grown by atmospheric pressure metalorganic vapor-phase epitaxy (AP-MOVPE) and the pulsed character of high-vapor-pressure metalorganic (MO) flows. ...
We report a cathodoluminescence (CL) study at helium temperature of oval defects on quantum well (QW) structures grown by molecular beam epitaxy (MBE). We collected the luminescence emitted both from the facet shaped defect and from the defect free growth ...
The indium desorption rates from InGaAs and InAlAs grown on InP substrates have been measured by wedge transmission electron microscopy as a function of the growth temperature. Desorption becomes significant at 545-degrees-C for both materials. No automatc ...
