  • 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 ± ...
  • The characterization of bulk as-grown and annealed ZnO by the Hall effect 
    Kassier, Gunter Horst (University of Pretoria, 2007-08-13)
    A fully automated Temperature Dependent Hall (TDH) measurement setup has been assembled for the purposes of this study. This TDH setup is capable of measuring samples in the 20 K to 370 K temperature range. Sample sizes ...
  • Electrical characterization of ZnO and metal ZnO contacts 
    Mtangi, Wilbert (University of Pretoria, 2010-05-26)
    The electrical properties of ZnO and contacts to ZnO have been investigated using different techniques. Temperature dependent Hall (TDH) effect measurements have been used to characterize the as-received melt grown ZnO ...
  • A novel CMOS Hall effect sensor 
    Mellet, Dieter Sydney-Charles; Du Plessis, M. (Elsevier, 2014-05)
    This paper reports on a new technique for sensing the Hall effect in an integrated CMOS device. Contrary totraditional Hall plates where sensor contacts comprise of highly doped, low ohmic contacts, the proposedsensor makes ...
