Abstract
Using a novel model, we investigate how moisture diffusivity affects the free surface of an elastic non-local semiconductor medium subjected to a 1D deformation. The purpose of this topic is to examine the interplay between the processes of moisture diffusivity and the plasma, thermo-elastic waves in the presence of laser pulses. The investigation takes place in the presence of a photo-thermo-elastic transport mechanism that is diffusive toward water vapor. The surface boundary plane is heated by a non-Gaussian laser beam with a 2-ps pulse on time. Using the Laplace transform method, we derive the equations that regulate elastic waves, carrier density, heat conduction, moisture, and the constitutive relationships for photo-thermo-elastic media. When mechanical stresses, temperatures, and plasma boundary conditions are applied to the Laplace domain, the underlying physical values are produced. Whole time-domain solutions for the key physical domains of interest are found using numerical inversion of the Laplace transform. Displacement component, moisture concentration, carrier density, force stress, and temperature distribution as a function of thermal memory, laser pulses, and reference moisture parameters are all shown graphically and discussed.
