Abstract

In this study, we investigated the effect of a rotation field and magnetic field on a homogeneous photo-thermoelastic nonlocal material and how its thermal conductivity changes as a result of a linearly distributed thermal load. The thermal conductivity of an interior particle is supposed to increase linearly with temperature under the impact of laser pulses. Microelastic (microelements distribution), non-local semiconductors are used to model the problem under optoelectronic procedures, as proposed by the thermoelasticity theory. According to the microelement transport processes, the micropolar-photo-thermoelasticity theory accounts for the medium’s microelongation properties. This mathematical model is solved in two dimensions using the harmonic wave analysis. Non-local semiconductor surfaces can generate completely dimensionless displacement, temperature, microelongation, carrier density, and stress components with the appropriate boundary conditions. The effects of thermal conductivity, thermal relaxation times, magnetic pressure effect, laser pulses, and rotation parameters on wave propagation in silicon (Si) material are investigated and graphically displayed for a range of values.
用脉冲激光加热具有不同热导率的微长非局部旋转半导体的光电热磁效应
在这项研究中,我们研究了旋转磁场和磁场对均质光热弹性非局部材料的影响,以及线性分布的热负荷如何改变其热导率。在激光脉冲的影响下,内部颗粒的热导率应该随温度线性增加。根据热弹性理论的建议,在光电程序下使用微弹性(微元素分布)、非局部半导体来模拟这一问题。根据微元素传输过程,微极-光-热弹性理论解释了介质的微伸长特性。这个数学模型是利用谐波分析在二维空间求解的。在适当的边界条件下,非局部半导体表面可产生完全无量纲的位移、温度、微伸长、载流子密度和应力分量。研究了热导率、热弛豫时间、磁压效应、激光脉冲和旋转参数对硅(Si)材料中波传播的影响,并以图形显示了一系列数值。
