Abstract
Purpose The purpose of this paper is to study the wave propagation in a non-homogenous semiconducting medium through the photothermal process using the fractional order photo-thermoelastic without neglecting the coupling between the plasma and thermoelastic waves that photogenerated through traction free and loaded thermally by exponentially decaying pulse boundary heat flux.
Design/methodology/approach The analytical solutions in the transformed domain by the eigenvalue approach were observed through the transform techniques of Laplace.
Findings Silicon-like semiconductor was used to achieve the numerical computations.
Originality/value Some comparisons are shown in the figures to estimate the effects of the fractional order and non-homogeneous parameters.
