Abstract(in English) | We grew GaAs/AlGaAs quantum well (QW) structures on two kinds of stripe-patterned structure simultaneously by molecular beam epitaxy methods. The employed stripe structures were fabricated on GaAs (100) substrate by photolithography and wet chemical etching. The stripe widths were 1 μm and 3 μm, and etching depth was 300 nm. The grown QW thickness estimated from the cathode luminescence spectra were 8 nm and 6.9 nm and the 1 μm and 3 μm stripes, respectively. This difference of thickness is due to the Ga adatoms surface diffusion from the (111) facets to the (100) surface. In 3 μm stripes on the QW thickness at the edge of the (100) surface is thicker than at the center. Therefore, we estimated the diffusion length of Ga adatoms on the surface less than 3 μm. |
