    In this study, the current–voltage (I–V) and capacitance–voltage (C–V) characteristics of Au/n-GaAs Schottky diodes have been measured over a wide temperature range, 80–480 K. The diodes were rectifying throughout the range ...

    Inductively coupled Ar plasma etching of n-type (Si doped) Gallium Arsenide (GaAs) introduces several electron traps, Ec – 0.04 eV (labelled E10), Ec – 0.19 eV, Ec – 0.31 eV, Ec – 0.53 eV, and Ec – 0.61 eV (behaving like ...

    The electronic properties of defects introduced by low energy inductively coupled Ar plasma etching of n-type (Sidoped)GaAs were investigated by deep level transient spectroscopy (DLTS) and Laplace DLTS. Several prominent ...
  • Goodman, Stewart Alexander (University of Pretoria, 1994)
    The beginning of the space-age in the 1950s led to interest in the effects of radiation on semiconductors. The systematic investigation of defect centres in semiconductors began in earnest over 30 years ago. In addition ...
