This research deals with the investigation of the vibrational behavior of thermoelastic homogeneous isotropic nanobeams, with particular emphasis on the application of non-Fourier heat conduction theory. The nanobeam is configured with one end having a graphene nano-strip connected to an electrical source supplying a low voltage current. To analyze this system, the Green-Naghdi type I and type III theorems are applied within the framework of simply supported boundary conditions while maintaining a fixed aspect ratio. The nanobeam is subjected to thermal loading due to the heat generated by the current flow through the graphene nano-strip. The governing equations are solved in the Laplace transform domain, and the inverse Laplace transform is computed numerically using Tzou's approximation method. Our results, as shown in the figures, reveal different scenarios characterized by varying electric voltage and electric resistance values for the nanographene strips. It is evident that these parameters exert a profound influence on the functional behavior of the nanobeam, thus providing a mechanism to regulate both its vibrational characteristics and temperature rise through judicious manipulation of the electrical voltage and resistance levels.

The objective of this article is to delve into the isotropic three-phase (3PH) lag magneto photo-thermoelastic (PTE) theory in semiconductor medium, with a special emphasis on its memory-dependent-derivative (MDD) characteristics. The equations for displacement, temperature distribution, carrier density, and stress components resulting from this theory are formulated using these characteristics and then transformed into a Fourier-Laplace vector matrix differential equation. This equation is solved using an eigenvalue approach, and the numerical solution is obtained by inverting Fourier and Laplace transforms. Graphical solutions based on the properties of silicon material are visualized using Mathematica software. The results demonstrate the excellence of MDD in this 3PH model by showing the effect of coupling between thermal, plasma, and elastic waves with the presence of time delay parameters and linear kernel function. Additionally, the presence of several kernel functions reveals significant differences in these magneto PTE quantities. This theory will aid in better characterizing materials, optimizing device design, and exploring non-linear and transient phenomena in greater detail. Ultimately, these advancements will push the boundaries of photo-thermal science and its practical applications.
