The effect of an applied gate electric field on the charge-order phase in β-(BEDT-TTF)2PF6 single-crystal field-effect transistor structure was observed at around room temperature by technical improvement with respect to sample preparation and electrical measurements. A relatively slight but systematic increase of the electrical conductance induced by the applied gate electric field and its temperature dependence was observed at around the metal-insulator transition temperature (TMI). The temperature dependence of the modulated electrical conductance demonstrated that TMI was shifted toward the lower side by application of a gate electric field, which corresponds to partial dissolution of the charge-order phase. The thickness of the partially dissolved charge order region was estimated to be several score times larger than the charge accumulation region.

AbstractA new design for a field effect transistor able to push back the physical limits of Moore's Law is described. An ab initio computational approach is presented that can be further developed to characterize the ON/OFF states of such a device. Distributed response analysis (M. in het Panhuis, P.L.A. Popelier, R.W. Munn, J.G. Ágyán (2001), J. Chem. Phys. 114, 7951-7961) is employed to investigate conductive behavior. The method demonstrates that in analogy to conduction an electron can move across a possible conjugated molecular switching element (para-nitroaniline) in an electric field.
