Bending strain induced thermal conductivity suppression in freestanding BaTiO3 and SrTiO3 membranes
Ziyan Qian, Guangwu Zhang, Weikun Zhou +2
Freestanding perovskite oxide membranes provide a novel platform for elastic strain engineering, enabling the manipulation of phonon transport free from substrate clamping. In this…
Interference-governed electromagnetic-thermal coupling and heat transport in pulse EUV-irradiated multilayer nanofilms
Hongyu He, Li Ma, Zhiyi Xie +6
Mo-Si multilayer mirrors are central to extreme ultraviolet lithography, where nanoscale optical interference and heat accumulation together constrain reflectivity and operational…
A Lindblad-Pauli Framework for Coarse-Grained Chaotic Binary-State Dynamics
Yicong Qiu, Qiye Zheng
Coarse-graining a chaotic bistable oscillator into a binary symbol sequence is a standard reduction, but it often obscures the geometry of the reduced state space and structural co…
Strain-Gradient-Driven Decoupling of Thermal Suppression from Anisotropy in \b{eta}-Ga2O3
Guangwu Zhang, Xing Xiang, Ziyan Qian +7
Strain gradients, ubiquitous in flexible devices and epitaxial nanostructures, are a major blind spot for thermal transport in \b{eta}-Ga2O3. We establish that strain gradient unlo…
Observation of Extraordinary Vibration Scatterings Induced by Strong Anharmonicity in Lead-Free Halide Double Perovskites
Guang Wang, Jiongzhi Zheng, Jie Xue +5
Lead-free halide double perovskites provide a promising solution for the long-standing issues of lead-containing halide perovskites, i.e., the toxicity of Pb and the low stability…
