Zn1 - xCdxSe/ZnSe quantum wells were grown by molecular beam epitaxy on GaAs substrates with a sub-micron grating along the [1 1 0]-direction. The synthesized structures were examined by means of transmission electron and scanning electron microscopy, proving that selective growth takes place. The reduced growth rate on the sidewalls of the grooves leads to a narrowing of the upper plateaux of the top ridges confining the two-dimensional layers laterally. From photoluminescence measurements of coherently grown samples, we can determine a blue shift with respect to the unpatterned reference samples. The blue shift of the grooves depends strongly on the total thickness of the ZnSe films, indicating complex strain effects in the layers.
