This paper investigates the behavior of a magneto-microstretch nonlocal semiconductor elastic medium under photothermal excitation. A theoretical model is formulated and analyzed within a two-dimensional (2D) framework, incorporating the microstretch and nonlocal effects to address wave propagation in the medium. The governing equations are transformed sequentially using the Laplace and Fourier transforms to facilitate their solution in the frequency domain. The system of coupled equations is systematically reduced to derive exact solutions for various physical parameters. Numerical results are presented to examine the influence of nonlocal parameters, initial magnetic field strength, and other contributing factors on the behavior of the medium subjected to laser pulse heating. Graphical representations illustrate the interdependencies among parameters and highlight their influence on the material’s photo-thermal and mechanical behavior, offering deeper insights into the complex dynamics of semiconductor materials. The findings provide valuable insights into the interplay of magneto-microstretch and nonlocal effects on semiconductor materials, with implications for advanced material design and wave propagation analysis.
