Abstract

The paper reports on results of an investigation of the electronic states of the conduction band of ultrathin films of furan-phenylene co-oligomer 1,4-bis(5-phenylfuran-2-yl)benzene (FP5) and the results of an investigation of the interfacial potential barrier upon the formation of these films on the surfaces of (SiO2)n-Si and of layer-by-layer deposited ZnO. Upon deposition of an 8–10 nm thick FP5 film, the total current spectroscopy (TCS) technique was used for investigation within the energy range from 5 eV to 20 eV above EF. FP5 films on the (SiO2)n-Si surface showed a domain structure with a characteristic domain size of the order of 1 micro.m × 1 micro.m and a surface roughness within the domain under 1 nm. In contrast, FP5 on the ZnO surface showed a granular structure with a grain height of 40–50 nm.
