Abstract:
In this study, a novel model is introduced when the Hall efect associated with a strong magnetic feld is taken into account when the electrons and holes interact in the processes of semiconductor material. Te plasma-elastic-thermal waves are investigated in the context of difusive processes during optical-generated transport processes. Te variable of thermal conductivity is obtained during graduated temperature due to the thermal impact of fallen light. Te governing equations of the novel model are investigated in a unidimensional (1D) way when the electronics and elastic deformations have occurred. Te Laplace transforms are used to convert the main dimensionless physical felds according to the initial conditions into the Laplace domain. When certain thermal, mechanical, holes, and electronic conditions are used, the analytical solutions of the fundamental felds can be produced to the outer surface of the semiconductor medium. Mathematically, the Laplacian computational inversion algorithm with a numerical approximation is used to achieve the fundamental physical quantities numerically in the time domain. Te infuences of several parameters (thermal relaxation times, Hall impact, and thermal conductivity parameters) on thermal conditions, mechanical stress, holes charge carrier feld, and carrier density are prescribed with the help of graphical diagrams that are discussed theoretically.
