dc-Hydrogen plasma induced defects in bulk n-Ge

Nyamhere, Cloud; Venter, Andre; Murape, D.M.; Auret, Francois Danie; Coelho, Sergio M.M.; Botha, J.R. (Elsevier, 2012-08)

Bulk antimony doped germanium (n-Ge) has been exposed to a dc-hydrogen plasma. Capacitance-voltage depth profiles revealed extensive near surface passivation of the shallow donors as evidenced by ˜ a 1.5 orders of magnitude ...
Thermal stability of Co, Ni, Pt or Ru Schottky contacts on n-Si and defects introduced thereon during contacts fabrication using electron beam deposition

Nyamhere, Cloud; Chawanda, Albert; Das, A.G.M.; Auret, Francois Danie; Hayes, M. (Elsevier, 2007-12-15)

When using Schottky barrier diodes (SBDs) on silicon (Si) to study the thermal stability of radiation-induced defects, point defects injection into the silicon substrate can occur at temperatures where silicidation occurs. ...
