Abstrakt: 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 show that the grwoth rates of GaAlAs and GaInAs layers, grown with trimethylgallium (TMG) and triethylgallium (TEG) sources, are of tens of Å per bubble for the methyl case and a few Å for the ethyl one.
