Precise control of directional heat flow is essential for advancing applications such as microchip cooling and building thermal regulation. However, existing methods often face challenges related to manufacturing complexity, structural instability, limited reversibility. Here, we present strain-gradient-induced crystal symmetry breaking an effective strategy achieve anisotropic conduction. We model a uniaxially bent silicon nanocube predict anisotropy ratio 1.20 at strain gradient 0.44%/nm...
Ceramic composites are essential materials for high-performance applications in aerospace, defense, and other industries requiring high-temperature structural components thermal barrier coatings. However, the understanding of heat transport processes at elevated temperatures, particularly heterogeneous interfaces, remains its early stages. In this study, we simulate properties SiC/Si interfaces various temperatures uncover an unexpected anomaly. At high interfacial resistance initially...
Boron arsenide (BAs) has emerged as a strong contender for next-generation functional materials, boasting desirable attributes such high thermal conductivity and ambipolar mobility. However, critical yet underexplored challenge lies in understanding its heat conduction capabilities under inhomogeneous strain, which is pivotal across various devices operational conditions. Here, through modeling transport bent BAs $\mathrm{Si}$ nanoribbons, striking difference revealed. Namely, the...
Strain engineering stands out as a promising avenue for manipulating the physicochemical characteristics of two-dimensional (2D) van der Waals (vdW) materials. Amidst flourishing investigations into modulation electronic band structures, influence elastic strain on evolution phonon spectra and, consequently, thermal transport has garnered comparatively less attention. Yet, this facet offers realm intricate physics and possibilities. Bending, process that couples in-plane (IP) cross-plane...
Tailoring heat flow in solids has profound implications for the innovation of functional thermal devices. However, current methods face technological challenges related to system complexity, material stability, and operating temperature. In this study, we demonstrated efficient modulation a single without phase transition, using simple entirely material-independent strategy, kinked nanostructure patterning, at near-ambient By carefully controlling kink arm length angle Si nanoribbons,...
