Surface doping in T6/ PDI-8CN2 Heterostructures investigated by transport and photoemission measurements

open access: yes, 2012
In this paper, we discuss the surface doping in sexithiophene (T6) organic field-effect transistors by PDI-8CN2. We show that an accumulation heterojunction is formed at the interface between the organic semiconductors and that the consequent band ...
