The effect of rotation and hydrostatic initial stresses during electromagnetic field which is fallen on the outer surface of semiconductor medium is studied. The Thomson influence in context of photo thermal excitation process is investigated. The thermoelectricity theory is applied explain the waves behavior in the elastic semiconductor homogenous, isotropic medium. The governing equations describe the overlapping between plasma, electro-magnetic and elastic waves in two dimensional deformations when the medium is in rotation. The induced electric current is studied only when the charge density is a function of time. The normal mode analysis is a mathematical method which is used to get the physical fields distributions under investigation. The mechanical forces, electromagnetic effects thermal loads and plasma diffusion recombination process are taken at the outer free surface of the medium to obtain the complete solutions. All distributions of waves of physical quantities are represented graphically and discussed under the influence of rotation, initial stresses and Thomson parameter.
