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.

摘要

在本研究中，讨论了光热理论下半导体介质中的表面波传播。一种厚度均匀的非粘性流体覆盖在无限的半导体半空间之上。上述问题的控制方程求解表面波解。沿两种介质的界面施加恒定大小的机械力。获得了半导体介质的界面位移、应力、载流子密度和温度分布分量。热电耦合参数对各种波的穿透深度也有影响。此外，流体层深度的影响由法向位移、法向力应力、载流子密度和温度分布的图形结果描述。
