The authors study the contact resistance of gold-pentacene interface by applying the transmission-line method to a few monolayers thick pentacene films in thin film transistor geometry. It was found that tetrafluorotetracyanoquinodimethane (F4TCNQ) doping reduces the contact resistance by more than a factor of 20. In addition, a significant improvement of the conductance of pentacene nanocrystals self-assembled on 10nm gap Au nanojunction devices by F4TCNQ doping is observed. The result demonstrates the importance of doping on the performance of organic electronic devices from 10nm scale up to 100μm scale.read more
