Abstract

The method of cross-sectional scanning tunneling microscopy (STM) is described. Illustrative examples are given of studies of III-V semiconductor systems, including low-temperature-grown (LT) GaAs, and InAs/GaSb superlattices. In each case, the STM permits the observation of structural features on an atomic scale. The associated electronic spectroscopy for states a few eV on either side of the Fermi-level can be determined. Such information is relevant for the operation of devices constructed from these layered semiconductor systems.

21. As shown in Ref. 15, tip-induced band bending effects are greatly reduced due to tunneling through the space charge region of the semiconductor. For bulk spectral features (band and subband onsets), corrections to the observed energies are thus less than 0.1-0.2 eV for doping levels near 1018 cm-3. Corrections to surface state related features can, in certain cases, be larger.Google Scholar
