Hall current impact on thermoacoustic wave propagation of rotating nonlocal hydro-semiconductors

This study investigates the influence of Hall currents on thermoacoustic wave propagation in rotating nonlocal hydrodynamic semiconductors, incorporating the photo-thermoelasticity theory within a two-dimensional framework. The coupled governing equations according to the Helmholtz vector for charge carriers, temperature, displacement, and stress are formulated to account for nonlocal effects, rotation, and Hall current phenomena. The normal mode analysis is employed to decouple and solve these equations, leading to an in-depth exploration of the wave propagation characteristics. Numerical computations are performed, and the results are graphically represented to demonstrate the effects of Hall currents and rotation parameters on thermal, acoustic, and mechanical responses. The findings provide valuable insights into the dynamic interactions within hydrodynamic semiconductor systems under the combined influences of these factors, highlighting their significance in advanced material and device applications.
