Te theory of photo-thermoelasticity describes how heating or elastic microstructure mechanical deformation can modify a material’s optical-thermal properties. Tis theory particularly highlights the efect of microtemperature on elasticity and efcient heat transport. Tis work provides a new theoretical framework for thermooptical elastic materials and clarifes the relationship between thermomechanical and plasma waves in microtemperature-afected semiconductors such as silicon. Te model focuses on studying the elasto-thermodifusion (ETD) theory’s electron-hole interaction. Microtemperature efects during photothermal (PT) stimulation are studied in this theory. In one-dimensional (1D) settings, the Laplace transform is utilized which can be solved using the governing equations for thermoelastic (TD) processes and electronic (ED) deformation processes in a nondimensional form. Te proposed model is put to use in analyzing how ramp-type heating afects an unbounded semiconductor material plane at rest. Te discussion section presents a series of graphs to analyze the efect of the main parameters.
