Mtangi, Wilbert; Nel, J.M.; Auret, Francois Danie; Chawanda, Albert; Nyamhere, Cloud; Diale, M. (Mmantsae Moche) (Elsevier, 2012-10)We report on the studies carried out on hydrogen peroxide treated melt grown, bulk single crystal ZnO samples. Results show the existence of two shallow donors in the as-received ZnO samples with energy levels (37.8 ± ...

Mtangi, Wilbert; Auret, Francois Danie; Chawanda, Albert; Jansen van Rensburg, P. J.; Coelho, Sergio M.M.; Nel, J.M.; Diale, M. (Mmantsae Moche); Van Schalkwyk, Louwrens; Nyamhere, Cloud (Elsevier, 2012-10)Current–voltage (IV) and capacitance–voltage (CV) measurement techniques have successfully been employed to study the effects of annealing highly rectifying Pd/ZnO Schottky contacts. IV results reveal a decrease in the ...

Coelho, Sergio M.M.; Auret, Francois Danie; Janse van Rensburg, Pieter Johan; Nel, J.M. (Elsevier, 2014-04)Inductively coupled plasma (ICP) etching of germanium introduces a single defect, the E0.31 electron trap, for a large range of argon partial pressures from 4 × 10-3 to 6.5 × 10-4mbar that correspond to ion energies of 8 ...
