Abstract
In this research, photo-thermoelasticity theory with phase lags was introduced and applied to an infinite semiconductor body in the form of a solid cylinder. The body is constricted and exposed to harmonic shifting heat. The essential equations overseeing the problem are unraveled utilizing the Laplace transform. To locate the analytical formulae of the physical amounts and to discover inverse Laplace transforms, we utilized a numerical technique. The detailed examination of the impacts of phase lags and the angular frequency of the thermal vibration on the absolute temperature, stresses, absolute carrier density, and displacement is considered.
