Abstract

Charge-carrier transport in the channel of bottom gate, top contact organic field effect transistors with anisotropic layers of 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS-Pentacene) obtained by zone casting was investigated using scanning Kelvin probe microscopy combined with atomic force microscopy. The TIPS-Pentacene continuous layers consisted of thin crystals unidirectionally oriented in the channel. Devices with perpendicular and parallel charge flow in the transistor channel were prepared. It was found that irregularities in the surface morphology at the semiconductor layer in the transistor channel are correlated with the local potential profile, and that the channel resistance strongly depends on the orientation of the TIPS-Pentacene crystals.

PHOTOELECTRICAL PROPERTIES OF INDANDIONE CHROMOPHORE IN SOLID STATE

The optically induced switching of electrical properties of indandione type molecules, which consist of acceptor and donor groups, are investigated. Both calculation and experimental results show a reversible highly dipolar photoinduced intramolecular electron transfer in 2-(4'-N, N-dimethylaminobenzyliden)indan-1,3-dione molecule (DMABI). Kelvin's probe technique is applied to investigate the surface potential of a host-guest polymer film with four different DMABI derivatives. The derivatives have been chosen to compare the influence of the geometry, concentration and dipole moment of a molecule in the ground and excited states on the response time and amplitude of photoinduced surface potential. It is shown that the time of fast response (up to several seconds) to irradiation is independent of the concentration of molecules in a polymer film. Dependence of the amplitudes of photoinduced changes in the surface potential on the molecules concentration is observed for DMABI and its three derivatives. The optimal concentration of guest molecules in the polymer matrix is in the range 10-25 wt% (depending on the molecule).
