| Abstract: | Combined ultra-high vacuum scanning tunneling/atomic-force microscopy (STM/AFM) has been implemented for the first time for
the tunneling spectroscopy of the size-quantized states in the InAs/GaAs(001) surface quantum dots (QDs). The tunneling spectra
and current images, which reflect the energy and spatial distribution of the local density of the ground and excited states
in the QDs have been obtained. |
