Effect of an excited non-local microelongated semiconductor with variable thermal conductivity on the propagation of photo-thermoelastic waves

An innovative concept of a microelongated non-local semiconductor material is developed. According to photothermal transport processes, the material is stimulated. When the thermal conductivity of the non-local medium is changed, the photo-thermoelasticity theories are used. The microelongation instance and the interference between the photothermoelastic propagation waves in the non-local medium are both described by the effective framework. When electronic and thermoelastic deformation processes are taking place, thermal conductivity may be thought of as a linear function of temperature. The dimensionless main fields are extracted using a maps converter in two dimensions (2D). The fundamental equations have been transformed into higher-order ordinary differential equations using the harmonic wave approach in accordance with the normal mode analysis. Applying a few conditions chosen from the non-local semiconductor surface yields complete solutions. With graphics, the numerical simulation results for silicon (Si) are shown. For the considered physical variables during the changing thermal conductivity and microelongation, comparisons are performed and explained.
