This study investigates the coupled effects of Hall currents, fractional heat conduction, and laser-pulsed excitation on wave propagation in a hydrodynamic semiconductor medium according to the photo-thermoelasticity theory. The normal mode method is employed to solve the governing equations, and graphical representations illustrate the impact of key parameters, including the fractional-order parameter, decay heat parameter, and Hall current strength. The results reveal that the Hall current significantly modifies charge carrier distribution and wave velocities, while fractional heat conduction introduces oscillatory and delayed thermal responses, affecting energy dissipation and stress dynamics. Furthermore, the decay heat parameter amplifies thermal and mechanical wave amplitudes, underscoring its role in energy transfer within the porous medium. The graphical analysis confirms significant deviations from classical thermoelastic models, highlighting the necessity of these advanced models for accurate semiconductor wave analysis. These findings provide valuable insights for optimizing semiconductor technologies, particularly in energy harvesting, optoelectronics, and laser-induced thermal management applications.
