The contribution of grain boundary barriers to the electrical conductivity of titanium oxide thin films [PDF]
, 2008 Titanium oxide thin films were prepared by reactive magnetron sputtering. The reactive gas pulsing process was implemented to control the oxygen injection in the deposition process and,consequently, to tune the oxygen concentration in the films from pure
