Charge transfer in a metal-polymer-nanocrystalline metal system

Polymer Thin Film Chemical Sensors

“…A thin transition layer with a structure differing from the bulk structure is apparently formed at the interface between the two polymers. We can assume that the interface between polymer films facilitates preferred antiparallel orientation of phthalide side fragments with an appreciable dipole moment (Lachinov et al, 2000). Such an orientation increases the local "2D" concentration of electron traps (phthalide side groups), which does not contradict the results obtained in (Schefefold et al, 1996).…”

“…Such an orientation increases the local "2D" concentration of electron traps (phthalide side groups), which does not contradict the results obtained in (Schefefold et al, 1996). The trapping of the excess charge injected from the electrodes to phthalide groups of poly(diphenylenephthalide) leads to the emergence of deep localized states in the polymer band gap (Duke & Fabish, 1976;Lachinov et al, 2000). These states ensure a higher conductivity level and modifies the shape of I-V curves upon the passage of current.…”

Smart Polymers as Basic for Bio-, Chemical and Physical Sensors

“…A thin transition layer with a structure differing from the bulk structure is apparently formed at the interface between the two polymers. We can assume that the interface between polymer films facilitates preferred antiparallel orientation of phthalide side fragments with an appreciable dipole moment [30] (Fig. 21.8).…”

Nanometer Scale Modifications of Si/Sio2 and Si/Sio2/Polymer Surfaces by Scanning Tunneling Microscope

“…It is well known that the processes on the metal-polymer interface affect significantly the electronic properties of thin polymer films, particularly due to influencing the characteristics of the potential barrier on the interface. This makes it possible to use such films like unique charge sensors [9,10]. The polymer film was obtained from a solution in cyclohexanone by the centrifugation on a silicon surface.…”
