Van Schalkwyk, Louwrens; Meyer, Walter Ernst; Auret, Francois Danie; Nel, Jacqueline Margot; Ngoepe, Phuti Ngako Mahloka; Diale, M. (Mmantsae Moche) (Elsevier, 2012-05)Intrinsically solar-blind ultraviolet (UV) AlGaN-based Schottky photodiodes were fabricated using Iridium oxide (IrO2) as the Schottky barrier material. The Ir Schottky contacts were annealed at 700 °C under O2 ambient and ...

Nyarige, Justine Sageka; Nambala, Fred Joe; Diale, M. (Mmantsae Moche) (Elsevier, 2022-12)In this study, the undoped, Erbium (Er) doped and Samarium (Sm) doped (1, 3, and 5 wt%) ZnO were synthesized using spray pyrolysis. X-ray diffraction patterns confirmed ZnO with strong diffraction peaks indexed in their ...

Chawanda, Albert; Nel, Jacqueline Margot; Auret, Francois Danie; Mtangi, Wilbert; Nyamhere, Cloud; Diale, M. (Mmantsae Moche); Leach, Lindsay Josephine (Korean Physical Society, 2010-12)We computed the homogeneous Schottky barrier height (SBH) at ideality factor (n) = 1.0 of Ni/n- Ge (100) Schottky diodes (SDs). The SDs were identically prepared by using resistive evaporation of Ni on n-Ge (100). The ...
