Plane wave propagation in a semiconducting medium under photothermal theory

Abstract

In the present investigation, surface wave propagation in a semiconducting medium under photothermal theory has been discussed. A non-viscous fluid of uniform thickness is overlying the infinite semiconducting half-space. The governing equations for the above problem are solved for surface wave solutions. A mechanical force of constant magnitude is applied along the interface of two media. The components of displacement, stresses, carrier density, and temperature distribution at the interface are obtained for the semiconducting medium. The effect of the thermoelectric coupling parameter is also shown on the penetration depth of various waves. Also, the effect of fluid layer depth is depicted by the graphical results for normal displacement, normal force stress, carrier density, and temperature distribution.
