| Abstract |
This study investigates the effects of rotational fields on the propagation of thermo-elastic
and optical waves in a hydrodynamic semiconductor medium, using normal mode analysis to explore
the dynamic interactions in this environment. Our analysis highlights the complex interplay between
rotational fields and wave propagation. The photo-thermoelasticity theory is applied to solve the coupled thermo-poro-opto-mechanical equations. The model applies hydrodynamic principles to a rotationally influenced semiconductor, treating it as a homogeneous medium responsive to combined
optical and acoustic wave excitations under specific boundary conditions of poroelastic semiconductors. Using normal mode analysis, we solve the non-dimensionalized field equations to obtain analytical expressions for the main physical fields. Our findings reveal that the rotational field significantly
alters the amplitude and phase of wave propagation in all physical fields, amplifying oscillatory behavior due to Coriolis and centrifugal effects. Numerical simulations using porous silicon parameters
demonstrate that both rotation and porosity enhance wave coupling and dispersion characteristics.
The results provide crucial insights into the dynamic behavior of advanced semiconductor materials
under rotational and thermal excitation, with potential applications in optoelectronics, plasma
devices, and rotating microelectromechanical systems (MEMS). |
