Research Abstract

We developed experimental method in investigating quantum chemical mechanism of the charge mobility, namely hopping and band transport mobility, and origin of the energy level alignment at interfaces in organic devices using high-precision ultraviolet photoelectron spectroscopy (UPS). The latter was realized by constructing ultrahigh-sensitivity UPS spectrometer that is effective to observe invisible electron density-of-states in the organic band gap even for radiation sensitive organic materials. We further found that the ultrahigh sensitivity UPS can also probe varied interfaces. Based on these results, we succeeded to directly bridge charge transport property and electronic states in organic semiconductors.
