Loss-Less Contacts

ESR of pristine ZnO nanoparticles in vacuum before and after UV illumination and subsequently after exposure to air. Change in resistance to Ohmic behavior for a ZnO/PEDOT PSS junction upon UV exposure. Burstein-Moss effect (blue shift) occurs upon UV illumination by emptying the valence band and filling the conduction band. Adapted with permission from ref. 104. Copyright 2007, AIP Publishing EEC.
