Evaluation of the energy distribution of trap states in polymer films

This paper reports on the results of an investigation of polymer thin films by the methods of thermally stimulated currents and current-voltage characteristics. It has been found using these methods that, in the band gap of the poly(diphenylene phthalide) films, there are three groups of electron traps with maxima in the density of states at energies of 0.50, 1.06, and 2.40 eV with respect to the bottom of the conduction band. These results correlate well with the data obtained in our investigation of the fluorescence excitation spectra.

Study of the charge carrier transport through a metal-poly(arylenephthalide)-class polymer interface

The influence of the chemical structure of the poly(arylenephthalide)-class polymers on the charge carrier transport through a metal/polymer interface has been discussed. On the basis of the results obtained by physical and optical methods and quantum chemical modeling, the conclusion is made that a change in the skeleton part of the polymer molecule leads to a substantial change in the value of the potential barrier.     

Resonance interaction of magnetoacoustic waves in refracting plasma waveguide

The resonance parametric interaction of magnetoacoustic modes in a plane plasma waveguide with an inhomogeneous transverse electron-density profile is analyzed. Shortened equations are obtained in an MHD approximation by solution of a nonlinear boundary value problem for the complex amplitudes of the MHD-wave triplet for an arbitrary plasma-parameter profile. A formula for the increment of decomposition instability is derived for the particular case of a parabolic dependence of plasma density.Scientific-Research Radio-Physics Institute.
