Fractional order photo-thermo-elastic waves in a two-dimensional semiconductor plate
This paper is devoted to the investigation of fractional order photo-thermo-elastic waves in a two-dimensional semiconductor using the eigenvalues approach. The formulations applied are based on the fractional order generalized thermo-elasticity in the context of the new model of heat conduction. The bounding surface of the plate is taken to be stress-free and exposed to a heat flux with the ... Read more

Generalized photo-thermo-elastic interaction in a semiconductor plate with two relaxation times
This study focuses on the effect of thermal relaxation times in a two-dimensional semiconductor medium by using eigenvalue approach. The formulation is applied under Green and Lindsay theory with two relaxation times. The bounding surface of the half-space is subjected to a heat flux with an exponentially decaying pulse and taken to be traction free. The variables solutions are obtained ... Read more

Analytical solutions of photo-thermo-elastic waves in a non-homogenous semiconducting material
In the present paper, the wave propagation on non-homogenous semiconductor through photo-thermal process has been studied by using the theory of coupled plasma and thermoelastic wave. Without neglecting the coupling between the plasma and thermoelastic wave that photo-generated through intensity modulated laser beam and tightly focused, a semiconducting isotropic elastic medium has non-homogeneity in thermal and elastic properties are considered. ...
