“…An electronic bandgap is very important parameter which has responsibility of many optical effects such as electron scattering mechanism by the atoms in a few nanometers scale [1]. The bandgap width has crucial role in the transport mechanism when an external electric field is applied to the material or optically stimulated.…”

The plasma parameters have been determined in an infrared image converter for the InP based plasma cell in a broad range of gas pressure from 10 Torr to 760 Torr at room temperature. The electrical properties of the system are controlled by both the plasma and InP electrode. InP has high electron mobility compared to other semiconductors and it can be used for high-speed optoelectronic device applications. Further, any small change in the charge transport mechanism may cause important changes in the system characteristics. The experimental measurements are carried out in air and He media. The homogeneity of the discharge radiation emission depends on the resistivity distribution of the photodetector plate and the radiation intensity is proportional to the plasma current. Local changes in the resistivity of the semiconductor result in local changes in the current and plasma emission.

This paper presents a conceptual framework for experimental research combined with numerical analysis on direct current (DC) glow discharges in microscale planar gas discharge-semiconductor systems (GDSS). In the experimental section, several structural and elemental analyses, including SEM, EDAX, AFM, and near-infrared absorption spectra measurements were carried out for compound semiconductor zinc selenide (ZnSe) cathode sample. Argon (Ar) was charged into the plasma reactor cell of GDSS at pressures of 100 Torr subatmospheric and 760 Torr atmospheric, respectively, by a vacuum pump- gas filling station. Glow discharge light emissions from plasma, excited under three different intensity levels (dark, weak, strong) of infrared beam illumination on ZnSe cathode electrode, were measured by using a phomultiplier tube that is sensitive to UV–Visible wavelengths. In the numerical analysis section, simulation studies were carried out on the two-dimensional gas discharge-semiconductor microplasma system (GDSµPS) cell models using the finite-element method (FEM) solver COMSOL Multiphysics DC plasma program. Calculations and predictions were based on mixture-averaged diffusion drift theory and Maxwellian electron energy distribution function. GDSµPS cell was modeled in a square chamber with planar anode/cathode electrode pair coupled at a 50 μm discharge gap. Single side of ZnSe cathode was finely micro-digitated to increase the effective surface area for enhanced electron emission to the gas discharge cell. The electrical equivalent circuit (EEC) of the proposed model was driven by 1.0 kV DC voltage source. Binary Ar/H2 gas medium in a mixture of 3:2 molar ratio was introduced to the gas discharge chamber at constant 200 Torr subatmospheric pressure. Simulations were run for normal glow discharges to exhibit the electrical fast transient glow discharge behaviours from electron field emission state to self-sustained normal glow discharge state by numerically solving the electron density (ED), electron current density (ECD) and electric potential distribution (EPD) parameters.It is figured out that binary Ar/H2 gas discharge model can undertake a major role in shaping and controlling the spatiotemporal response to transient electro-optical behavior of microplasma-based artificial electromagnetic materials configured for high-efficiency infrared-to-visible wavelength conversion applications.
