Electromagnetic Wave Instability with Dynamic Charge Fluctuation in Semiconductor

Abstract

In nature, the gravitational tragedy has been observed. Electromagnetic perturbations are the only reason of these gravitational tragedies. In quantum plasmas, these types of perturbations (electromagnetic) are propagated by cause of magnetic densities along with the manifestation of magnetic field. This study will cover the analytical and numerical features of electromagnetic waves in semiconductor quantum plasmas in the presence of external magnetic field including the quantum effects. The discussion will be based on the quantum effects like Fermi statistical pressure, Bohm tunneling potential and spin-based exchange correlation effects. The dust charging will be dynamical with respect to the time. The plasmas are omnipresent in space, interstellar and the dense astrophysical environment as well as in the metals and the semiconductors. The presence of charge species in plasmas ensures the plasma system to host variety of waves and the instability features. This work evolves around the semiconductor medium as a plasma system. In the semiconductor systems, the dust is produced in fabrication. The dust is charged either positive or negative. The dust charging is source of new features evolved at micro and nano scales. This study will cover the analysis of electromagnetic waves in semiconductor electron-hole plasmas in the presence of charge variation. The quantum effects will be included on taking different terms used in plasma which explain the quantum effect in equation of motion like Bohm criterion, exchange correlation and fermi pressure. The quantum features of plasma physics explored up a new area of research due to its wide range of application.
