Twin Mechanical Metamaterials
Wenwang Wu, Seok Kim, Ali Ramazani +2
By mimicking the geometrical relation of nano-twin crystals, we propose novel architected twin mechanical metamaterials (TMMs), which can impede local shearing band formation under…
Giant Polarization and Abnormal Flexural Deformation in Bent Freestanding Perovskite Oxides
Songhua Cai, Yingzhuo Lun, Dianxiang Ji +15
Recent realizations of ultrathin freestanding perovskite oxides offer a unique platform to probe novel properties in two-dimensional oxides. Here, we observed a giant flexoelectric…
Flexo-diffusion effect: the strong influence on lithium diffusion induced by strain gradient
Gao Xu, Feng Hao, Mouyi Weng +3
Lithium ion batteries (LIBs) work under sophisticated external force field and its electrochemical properties could be modulated by strain. Owing to the electro-mechanical coupling…
Strain gradient drives lithium dendrite growth from the atomic-scale simulations
Gao Xu, Feng Hao, Jiawang Hong +1
Dendrite formation is a major obstacle, such as capacity loss and short circuit, to the next-generation high-energy-density lithium (Li) metal batteries. The development of success…
Structural Stability and Optoelectronic Properties of Tetragonal MAPbI3 under Strain
Lei Guo, Gao Xu, Gang Tang +2
In recent years, organic-inorganic hybrid perovskites have attracted wide attention due to their excellent optoelectronic properties in the application of optoelectronic devices. I…
Anomalous lattice thermal conductivity in layered materials MNCl (M=Zr, Hf) driven by the lanthanide contraction
Xiaoxia Yu, Hezhu Shao, Xueyun Wang +3
High performance thermoelectric devices requires materials with low lattice thermal conductivities. Many strategies, such as phonon engineering, have been made to reduce lattice th…
