Dependence of indium–tin–oxide work function on surface cleaning method as studied by ultraviolet and x-ray photoemission spectroscopies
TL;DR: In this article, the effect of the method used to clean indium-tin-oxide (ITO) on its work function was investigated by ultraviolet photoemission spectroscopy (UPS) and x-ray photo-emission spectrum analysis (X-ray PSA) and it was shown that C-containing contaminants, O/In ratio, and In/Sn ratio on the ITO surface affect the work function.

Energy level alignment at organic/metal interfaces studied by UV photoemission: breakdown of traditional assumption of a common vacuum level at the interface
Hisao Ishii,Kanako Seki +1 more
TL;DR: In this paper, the electrical properties of model interfaces of organic electroluminescent (EL) devices and porphyrin/metal interfaces were investigated by UV photoemission spectroscopy (UPS).

Theoretical study of n-alkane adsorption on metal surfaces
TL;DR: In this paper, the interaction between n-alkane and metal surfaces has been studied by means of density-functional theoretical calculations within a generalized gradient approximation (GGA), and it was shown that although the GGA cannot reproduce the physisorption energy well, their calculations can reproduce the experimentally observed work-function change and softening of the CH stretching mode reasonably well.
