홈페이지논문 초록 (Abstract)
Improving the electrical performance of organic semiconductors is critical to use them for optoelectronic applications. In this study, we analyze the mechanism of charge transfer complex (CTC) formation at the interface between organic and inorganic semiconductors through extensive optical and electrical measurements. N,N -Bis (naphthalen-1-yl)-N,N-bis(phenyl)benzidine (NPB) and molybdenum oxide (MoO3) were sequentially deposited to form a donor/accepter heterojunction structure. The CTC formation and conductivity of the films were determined using UV-visible spectroscopy and transmission line method, respectively. Compared with the single layer devices, the donor/accepter heterojunction exhibits significantly enhanced conductivity. In addition, the conductivity and CTC generation efficiency of the heterojunction display strong dependence on NPB layer thickness, which originates from the variation of dipole interactions at the heterojunction interface. These results provide useful insights on interfacial doping properties, which is potentially beneficial for enhancing the understanding of organic/inorganic interfaces.
