Title Influence of tellurium doping on step bunching of GaAs (001) vicinal surfaces grown by organometallic vapor phase epitaxy
Date 1998
Description Atomic force microscopy has been used to investigate the influence of controlled tellurium Te incorporation on the step structure of GaAs grown by organometallic vapor phase epitaxy on vicinal 001 surfaces. Te doping, using the precursor diethyltelluride, is found to markedly decrease the surface roughness. Step bunching, observed for undoped layers, is totally eliminated. Only monolayer steps are formed for Te concentrations of 4 1017 cm 3. A model is proposed to account for these effects and the results reported previously for GaInP.
