Annealing and surface conduction on hydrogen peroxide treated bulk melt grown, single crystal ZnO

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 ± ...
Comparative study of the electrical properties of Pd/ZnO Schottky contacts fabricated using electron beam deposition and resistive/thermal evaporation techniques

Mtangi, Wilbert; Auret, Francois Danie; Janse van Rensburg, Pieter Johan; Coelho, Sergio M.M.; Legodi, Matshisa Johannes; Meyer, Walter Ernst; Chawanda, Albert (American Institute of Physics, 2011-11)

A systematic investigation to check the quality of Pd Schottky contacts deposited on ZnO has been performed on electron beam (e-beam) deposited and resistively/thermally evaporated samples using current-voltage, IV, and ...
Effect of Sm doping ZnO nanorods on structural optical and electrical properties of Schottky diodes prepared by chemical bath deposition

Ahmed, Mustafa Abaas Mohamedelkhair; Mwankemwa, Benard S.; Carleschi, E.; Doyle, B.P.; Meyer, Walter Ernst; Nel, Jacqueline Margot (Elsevier, 2018-06)

Please read abstract in the article.
Electronic properties of defects in pulsed-laser deposition grown ZnO with levels at 300 and 370 meV below the conduction band

Auret, Francois Danie; Meyer, Walter Ernst; Janse van Rensburg, Pieter Johan; Hayes, M.; Nel, Jacqueline Margot; Von Wenckstern, Holger; Schmidt, H.; Biehne, G.; Hochmuth, H.; Lorenz, M.; Grundmann, Marius (Elsevier, 2007-12)

Optical selection rules and scattering processes in rocksalt wide band gapZnO

Kunert, Herbert W.; Govender, Malcolm; Machatine, Augusto Gonçalo Jose; Mwakikunga, B.W.; Niyongabo, Prime (Wiley-Blackwell, 2014-02)

At sufficiently high pressures, wurtzite structure zinc oxide (WZnO) can be transformed to the cubic rocksalt (R-ZnO) structure. The R-ZnO exhibits semiconductor behavior with an indirect wide band gap of Eg ¼ 5:5 eV. ...
Radiation damage in ZnO ion implanted at 15 K

Wendler, E.; Bilani, O.; Gartner, K.; Wesch, W.; Hayes, M.; Auret, Francois Danie; Lorenz, K.; Alves, E. (Elsevier, 2009)

Commercial O-face (0 0 0 1) ZnO single crystals were implanted with 200 keV Ar ions. The ion fluences applied cover a wide range from 5 x 1011 to 7 x 1016 cm-2. The implantation and the subsequent damage analysis by ...
Simonkolleite nano-platelets : synthesis and temperature effect on hydrogen gas sensing properties

Sithole, J.; Ngom, Balla D.; Khamlich, Saleh; Manikanadan, E.; Manyala, Ncholu I.; Saboungi, M.L.; Knoessen, D.; Nemutudi, R.; Maaza, Malik (Elsevier, 2012-08)

Please read abstract in article.
A study of the T2 defect and the emission properties of the E3 deep level in annealed melt grown ZnO single crystals

Mtangi, Wilbert; Schmidt, Matthias; Auret, Francois Danie; Meyer, Walter Ernst; Janse van Rensburg, Pieter Johan; Diale, M. (Mmantsae Moche); Nel, Jacqueline Margot; Das, A.G.M.; Ling, F.C.C.; Chawanda, Albert (American Institute of Physics, 2013-05-22)

We report on the space charge spectroscopy studies performed on thermally treated melt-grown single crystal ZnO. The samples were annealed in different ambients at 700 C and also in oxygen ambient at different temperatures. ...
