摘要：

The possibility is demonstrated of using the STM for recording spectra of photoconductivity of quantum-dimensional semiconductor structures with a high 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 surface space charge region. For quantum points in the vicinity of the sample surface, spectra are obtained which are characterized by features associated with the individual energy spectrum of those points.
