Research Abstract

Probing method for electron-transfer dynamics of conduction electron using core-hole lifetime has been applied to organic conductor. The core hole acts as one of the fastest internal clock ranging from femtoseconds down to even attoseconds (ultrafast stopwatch). X-ray photon energy dependence of resonant Auger electron spectra was measured and analyzed for organic charge-transfer complexes, polymers related to polythiophene and organic photovoltaic materials. It was found that several organic conductors reveal metal-like ultrafast electron transfer through conduction band.
