Abstract
The topography of InP and Ga0.47In0.53As surfaces grown by organometal lic vapor phase epitaxy (OMVPE) was investigated using atomic force mi croscopy (AFM). Monolayer steps with atomically flat terraces, several hundred nanometers width, were formed for both InP and GaInAs. The bo undary growth condition between step flow mode and 2D-nucleation mode was studied for InP and GaInAs, respectively. Applying step flow mode to the growth of GaInAs/InP resonant tunneling diodes, a remarkable re duction of the energy level width fom 51 to is meV was observed.
