摘要:

Oxygen vacancies in MoOx play an essential role in interface energetics for charge injection and transport in organic devices. The influence of oxygen vacancy on energy-level alignment at the interface between MoOx and organic hole-transport layers is studied via photoemission spectroscopy. The degree of oxygen vacancies in MoOx is controlled by thermal annealing, which results in the partial reduction of Mo cations and a decrease in their work function. The hole-injection barrier at MoOx/organic interfaces increases as a consequence of the increase in oxygen deficiency.
