Photo-thermoelastic interactions in a 2D semiconducting medium

Photo-thermoelastic interactions in a 2D semiconducting medium
Photo-thermoelastic interactions in a two-dimension semiconductor medium are studied by using mathematical methods in the context of coupled thermoelastic theory and plasma waves with one thermal relaxation time. The Laplace-Fourier transformations and eigenvalues approach are used to obtain the general solutions for any set of boundary conditions. The medium is initially assumed to be at rest and due to a ... إقراء المزيد

The effect of fractional derivative on photo-thermoelastic interaction in an infinite semiconducting medium with a cylindrical hole

The effect of fractional derivative on photo-thermoelastic interaction in an infinite semiconducting medium with a cylindrical hole
In the present paper, the theory of generalized photo-thermoelasticity under fractional order derivative was used to study the coupled of thermal, plasma, and elastic waves on unbounded semiconductor medium with a cylindrical hole during the photo-thermoelastic process. The bounding surface of the cavity was traction free and loaded thermally by exponentially decaying pulse boundary heat flux. The medium was considered ... إقراء المزيد

Fractional Order Photo-Thermoelastic Interaction in a Semiconducting Media Containing a Spherical Cavity Subjected to Pulse Heat Flux

Fractional Order Photo-Thermoelastic Interaction in a Semiconducting Media Containing a Spherical Cavity Subjected to Pulse Heat Flux
In the present study, the theory of generalized photo-thermoelasticity under fractional order derivative was used to investigate the coupled of thermal, plasma, and elastic waves on unbounded semiconductor medium with spherical hole during the photothermoelastic process. Without neglecting the coupling between the thermoelastic and plasma waves that photo-generated through intensity modulated laser beam and tightly focused, a semiconducting isotropic elastic ... إقراء المزيد
