In the current work, we investigate a novel technique specialized in stability perturbation theory to analyze the primary variations such as thermal, carrier, elastic, and mechanical waves in photothermal theory. The interface of the non-local semiconductor material is utilized to study the stability analysis. The problem is established using a 1D opto-electronic-thermoelastic deformation in the context of the photo-thermoelasticity (PTE) framework. The Laplace transform method is used to convert the system from the time domain into the frequency domain, and the boundary conditions for the thermal, elastic, and plasma waves are applied to the interface of the medium. The homotopy perturbation method was used as an innovative approach to analyze the stability of the non-local silicon's primary physical fields. The numerical inversion method is applied, yielding many graphs focusing on important numerical factors such as non-local effects, thermo-energy, and thermo-electric coupling parameters. Investigating dual solutions between stable and unstable regions for critical parameters like thermo-electric and thermo-energy coupling factors demonstrates that the homotopy perturbation technique can effectively analyze the stability analysis. The comparison between silicon and germanium is illustrated graphically. Utilizing the homotopy perturbation technique, we can effectively examine the stability of the primary physical variations with the effect of some values for eigenvalues approaches.

Influence of the homotopy stability perturbation on physical variations of non-local opto-electronic semiconductor materials.

Based on the coupled thermoelasticity theory, this study presents a stochastic analysis of opto-acoustic wave propagation in non-local semiconductor media subjected to magneto-photo-thermal effects. The model incorporates magnetic field influence and non-local elasticity to capture realistic semiconductor behavior. Stochastic thermal fluctuations are introduced through a Wiener process, enabling a probabilistic framework to assess uncertainty in the system response. The governing equations are solved analytically, yielding explicit expressions for the main physical fields, including displacements, stresses, temperature, acoustic pressure, carrier density, and strain. To examine the influence of physical parameters, the effects of the non-local parameter and magnetic field intensity are systematically investigated. In addition, stochastic envelope estimation is conducted using 30 and 500 realizations to evaluate the statistical behavior of physical responses. Results demonstrate that increasing the number of realizations significantly reduces noise and sharpens the approximation of the mean solution. Finally, a heat map is generated for the 500-realization case to visualize the system's spatial distribution and intensity of uncertainty. This work provides valuable insights into the dynamics of semiconductor media under combined magneto-photo-thermal and stochastic excitation, emphasizing acoustic pressure behavior and its interaction with non-local and magnetic effects.
