Gora, V.E.; Chawanda, A.; Nyamhere, C.; Auret, Francois Danie; Mazunga, F.; Jaure, T.; Chibaya, B.; Omotoso, Ezekiel; Danga, Helga Tariro; Tunhuma, Shandirai Malven (Elsevier, 2018-04)We have investigated the current-voltage (I-V) characteristics of nickel (Ni), cobalt (Co), tungsten (W) and palladium (Pd) Schottky contacts on n-type 4H-SiC in the 300–800 K temperature range. Results extracted from I-V ...

Danga, Helga Tariro; Auret, Francois Danie; Coelho, Sergio M.M.; Diale, M. (Mmantsae Moche) (Elsevier, 2016-01)The defects introduced in epitaxially grown p-type silicon (Si) during electron beam exposure were electrically characterised using deep level transient spectroscopy (DLTS) and high resolution Laplace-DLTS. In this process, ...

Tunhuma, Shandirai Malven; Auret, Francois Danie; Nel, Jacqueline Margot; Omotoso, Ezekiel; Danga, Helga Tariro; Igumbor, Emmanuel; Diale, M. (Mmantsae Moche) (Elsevier, 2017-10)We have used deep level transient spectroscopy (DLTS) and Laplace DLTS (L-DLTS) to characterize the electrically active point defects introduced in n-type gallium arsenide by electron beam exposure prior to Schottky ...

Danga, Helga Tariro; Auret, Francois Danie; Tunhuma, Shandirai Malven; Omotoso, Ezekiel; Igumbor, Emmanuel; Meyer, Walter Ernst (American Institute of Physics, 2019-06-03)In this paper, we report on defects introduced in epitaxially grown n-type silicon (Si) during electron beam exposure. The defects observed were electrically characterized using deep-level transient spectroscopy (DLTS) ...

Chitake, Olivia; Ndlovu, Nothando; Matandirotya, Electdom; Mazunga, Felix; Sumanya, Clemence; Danga, Helga T. (AIP Publishing, 2023)Gender imbalance impedes the participation of women in physics. The number of women in physics in Zimbabwe remains very low relative to men. The few women who graduate with BSc degrees in physics change professions or ...
