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. ...
Current–temperature measurements of a SBD evaporated onto inductively coupled plasma cleaned germanium

Coelho, Sergio M.M.; Auret, Francois Danie; Myburg, G.; Janse van Rensburg, Pieter Johan; Meyer, Walter Ernst (Elsevier, 2009)

Inductively coupled plasma (ICP) etching has been used primarily on compound semiconductors. There are however compelling reasons to study the effects of ICP etching on Ge. Pd Schottky barrier diodes (SBDs) were resistively ...
Radiation damage in ZnO ion implanted at 15 K
