  • The effect of high temperatures on the electrical characteristics of Au/n-GaAs Schottky diodes 
    Tunhuma, Shandirai Malven; Auret, Francois Danie; Legodi, Matshisa Johannes; Diale, M. (Mmantsae Moche) (Elsevier, 2016-01)
    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 ...
  • Field dependence of the E1' and M3' electron traps in inductively coupled Ar plasma treated n-Gallium Arsenide 
    Venter, Andre; Nyamhere, Cloud; Botha, J.R.; Auret, Francois Danie; Coelho, Sergio M.M.; Meyer, Walter Ernst (American Institute of Physics, 2012-05-01)
    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 ...
  • Inductively coupled plasma induced deep levels in epitaxial n-GaAs 
    Venter, Andre; Nyamhere, Cloud; Botha, J.R.; Auret, Francois Danie; Janse van Rensburg, Pieter Johan; Meyer, Walter Ernst; Coelho, Sergio M.M.; Kolkovsky, V.I. (Elsevier, 2012-05)
    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 ...
  • Influence of particle irradiation on the electrical and defect properties of GaAs 
    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 ...
