A general solution for propagating waves in a generalized piezo-photo-thermoelastic medium for the one-dimensional (1D) problem under the hyperbolic two-temperature theory is investigated. The governing equations of the elastic waves, carrier density (plasma wave), quasi-static electric field, heat conduction equation, hyperbolic two temperature coefficient and constitutive relationships for the peizo-thermoelastic medium are obtained using Laplace transformation method in 1D. On the interface adjacent to the vacuum, mechanical stress loads, thermal and plasma boundary conditions are applied to obtain the main basic physical quantities in the Laplace domain. The inversion of Laplace transform by a numerical method is applied to obtain the complete solutions in the Laplace time domain for the main physical fields in this phenomenon. The effects on the force stress, displacement component, temperature distribution and carrier density of the thermoelastic, thermoelectric and hyperbolic two-temperature parameters by the applied force were graphically discussed.

半导体材料双曲双温度理论的压电光热弹性输运过程

研究了双曲线两温度理论下一维(1D)问题在广义压电光热弹性介质中传播波的一般解。利用一维拉普拉斯变换方法,得到了压电热弹性介质的弹性波、载流子密度(等离子波)、准静态电场、热传导方程、双曲线二温度系数和本构关系的控制方程。在与真空相邻的界面上,应用机械应力载荷、热和等离子体边界条件来获得拉普拉斯域中的主要基本物理量。应用数值方法对拉普拉斯变换进行反演,得到该现象中主要物理场在拉普拉斯时域的完全解。
