Work function modification of indium–tin–oxide used in organic light emitting devices
Abstract
We report measurements on the modification of the work function (WF) of indium–tin–oxide (ITO) by deposition of Au and Pt overlayers, chosen because of their high WF and inertness. ITO films on glass substrates (resistance∼10 Ω/sq) were cleaned with an ultraviolet (UV)–ozone treatment before entry into an ultrahigh vacuum system. Auger electron spectroscopy was used to determine the surface composition. The change of WF of the surface (±10 mV) …
