Abstract

AFM image analysis of 12 nm thick In0.2Ga0.8As grown on GaAs demonstrated a very smooth surface with average rms of ∼3.5 Å. The rms value increased with In% at the same growth temperature. Within the temperature range of 410-440°C, there was no trend of rms change observed for InGaAs/GaAs. AFM images of 12 nm thick samples showed the initial formation of the InGaAs surface waves.
