Abstract:In order to comprehensively explore the intricate mechanisms
of
thermo-mechanical interactions, this study employs the molecular dynamics
method to investigate the influence of heat flux density, shell thickness
and length, as well as stress on the radial interface phonon transport
in GaN/SiO2 core/shell nanowire. Additionally, the surface
eigenmode decomposition method is employed to analyze the interface
phonon dispersion curves. The investigation reveals that with increasing
heat flux density, internal ther… Show more
