A new Monte-Carlo simulation algorithm has been applied to verify the concept of the effective temperature recently suggested as a description of energy relaxation of carriers in band tails of amorphous semiconductors under the presence of an applied electric field. The algorithm allows the simulation with arbitrary applied field and finite temperature. The results of the simulation agree favourably with the theoretical prediction.

Nonlinear Relaxation

Relaxation oscillations of optical transmittance after the turn-off of the applied electric field of liquid crystals are observed when the detected light transmits through a proper adjustment of the alignment of the polarizer and analyzer. Monte Carlo simulation of the equilibrium tilting and twisting angles of molecules at each layer that yield relevant polarization of the transmitted light can satisfactorily portrait this phenomenon. Optics of an isotropic-layered liquid crystal with the extended Jones 4 × 4 matrix formalism is implemented to solve this problem. The transmittance under linear changes of temperatures also reveals similar nonlinear relaxation oscillations.

The parallelization aspect of the Ising Monte Carlo simulation is discussed. It is shown that most of the theoretically interesting simulations now are suitable for the trivial parallelization, that is, the Ising simulation is ideally parallelizable. Furthermore, presently most efficient simulation algorithm for single processor is also a kind of trivial paralellization. Results on the non-equilibrium critical relaxation study is included as an example.

Streamer Propagation

There has been considerable interest in non-thermal discharges over the past decade due to the increased number of industrial applications. The properties of discharges in electronegative gases are most frequently used for technological applications. For the improvement of performance in these applications, it is necessary to understand discharge dynamics experimentally and numerically. In this paper, a Monte Carlo simulation is carried out in sulfur hexafluoride (SF6) in uniform electric fields. The streamer propagation, electron, positive and negative ion distributions and space charge fields are studied in detail as time increases.
