Effect of air exposure of MoO3 film underneath thin CuPc layers
Published online by Cambridge University Press: 25 January 2013
Abstract
Wehave investigatedthe thickness dependence of air exposure of copper phthalocyanine (CuPc) layerson molybdenum trioxide (MoO3) with ultraviolet photoemission spectroscopy (UPS). It was found that after the air exposure, the WF of MoOx dropped severely. Meanwhile, with ∼10 ÅCuPcthin films covered on the top, there is no big change of the MoOx WF before and after the air exposure.
