Here we present an equivalent circuit model for the study of the surface discharge induced plasma chemical process (SPCP). The simplified model consists of a series of gaseous and ceramic capacitors. The discharge characteristics of the SPCP device are investigated based on this model. The discharge current, the average length of the streamer filaments, the inception breakdown voltage, the density of the surface charges, the dynamic capacity and the effective energy associated with the discharge process are simulated. The computed results are in good agreement with the experimental data.

We investigate the coupling of an inhomogeneous electron system to phonons. The properties of an electronic system composed of a mixture of microscopic ordered and disordered islands are changed fundamentally by a phonon mode. In high-T c cuprates, such a phase separation scenario is supported by recent STM and nuclear quadrupole resonance studies. We show that even a weak or moderate electron-phonon coupling can be sufficient to produce dramatic changes in the electronic state of the inhomogeneous electron gas. The spectral properties calculated in our approach provide a natural explanation of the low-energy nodal ARPES features and exhibit a novel non-Fermi-liquid state stabilized through electron-phonon coupling.
