Abstract
The possibility is demonstrated of using the STM for recording spectra of p hotoconductivity of quantum-dimensional semiconductor structures with a hig h spatial resolution. Studies are made into the local photoconductivity of GaAs/InxGa1-xAs based quantum wells and quantum points as a function of the depth of location of the quantum-dimensional structure relative to the sur face space charge region. For quantum points in the vicinity of the sample surface, spectra are obtained which are characterized by features associate d with the individual energy spectrum of those points.
