摘要：
By applying a shallow etching technique, the electrons in a remote doped GaAs/AlGaAs quantum well and the photogenerated holes are separated into adjacent lateral regions. The dominant photoluminescence of these carriers is shown to be indirect in real space. In addition, a spatially direct luminescence is observed. Its origin depends on the type of structuring and is discussed for wires, dots and antidots in comparison with unstructured samples.
