摘要：

A new method for doping organic semiconductors is presented. The most common dopant for the widely used alpha-sexithiophene (alpha6T), FeCl3, was co-sublimed with the oligothiophene under UHV-conditions. The solid-state doping effects were studied for systematically varied dopant concentrations in-situ with XPS, UPS, and HREELS. Up to a doping level of one effective charge per alpha6T the results can be interpreted as polaron formation. At higher dopant concentrations polaron bands are most probably formed.
