Studying the Thermoelastic Waves Induced by Pulsed Lasers Due to the Interaction between Electrons and Holes on Semiconductor Materials under the Hall Current Effect

In the present work, interaction between electrons and holes in semiconductor materials is investigated. According to excitation process, optical-elastic-thermal-diffusion (OETD) process considered when medium exposed a strong magnetic field laser pulses. Photo-elastic photo-electronics deformations are taken into account Hall current impact appears due pressure on medium. Due complexity of model, governing equations that describe system one dimension (1D) studied. Mathematical transformations (Laplace transform) were used simplify obtain physical quantities under study which affected by To complete solutions, some conditions obtained from free surface as well mechanical ramp type pulse heat flux, then numerical applied using inverse Laplace transform. Under influence several variables this question, results explained graphically for silicon (Si) material analyzed terms their significance.
