- 論文の詳細を見る
A new measurement technique, reflectance-based optically detected resonance (RODR), was used to study the neutral and negatively charged donors in GaAs/AlGaAs quantum well structures. The magnetic field was applied externally to bring the internal transitions among several impurity states into resonance with the far-infrared (FIR) photon energy. Internal transitions of negatively charged donors were observed and were found to be in good agreement with theoretical calculations. These results demonstrate that the RODR technique is a useful tool for the study of donor states in semiconductor quantum wells.
