Fractional heat conduction with variable thermal conductivity in rotating hydro-semiconductors

This work introduces a novel framework for analyzing wave propagation in hydro-semiconductors by simultaneously incorporating fractional-order heat conduction, temperature-dependent thermal conductivity, and rotational effects into a unified photo-thermoelastic model. Unlike previous studies that considered these effects separately, the present model couples nonlocal fractional heat transport with variable thermal conductivity in a rotating semiconductor medium. Analytical solutions are obtained using the normal mode method, and numerical results illustrate how fractional derivatives and temperature-dependent conductivity jointly reshape thermal, mechanical, and carrier wave behaviors compared to classical theories. The findings provide new physical insights into nonlocal, memory-driven, and anisotropic transport phenomena in advanced semiconductor systems, which are not captured by conventional thermoelasticity models.
