Polymer-inspired mechanical metamaterials
Zhenyang Gao, Pengyuan Ren, Yifeng Dong +18
Metamaterials benefit from unique architected patterns to achieve lightweight with exceptional mechanical properties inaccessible to conventional materials. Typical mechanical meta…
Wavelength-dependent photo-creep in halide perovskite single crystals
Ruitian Chen, Jincong Pang, Lizhong Lang +9
Halide perovskites are promising optoelectronic materials, but their time-dependent permanent deformation under illumination (i.e., photo-creep) is poorly understood, limiting thei…
Compositional Complexity-Induced Ultralow Friction in Medium-Entropy MXenes
Jiaoli Li, Yuwei Zhang, Congjie Wei +11
Two-dimensional MXenes are promising solid lubricants, but the roles of compositional complexity and surface chemistry in governing interfacial friction remain unclear. Here, we sy…
Diamond-to-graphite transformation under hypersonic impact
Abhijit Biswas, Aniket Mote, Rajib Sahu +22
Diamond to graphite transformation is a complex kinetically driven process which has been studied under various conditions for its fundamental importance. We report the transformat…
Direct evidence and atomic-scale mechanisms of reduced dislocation mobility in an inorganic semiconductor under illumination
Mingqiang Li, Kun Luo, Xiumei Ma +5
Photo-plasticity in semiconductors, wherein their mechanical properties such as strength, hardness and ductility are influenced by light exposure, has been reported for several dec…
High-magnitude, spatially programmable, and sustained strain engineering of 2D semiconductors
Boran Kumral, Pedro Guerra Demingos, Peter Serles +13
Crystalline two-dimensional (2D) semiconductors often combine high elasticity and in-plane strength, making them ideal for strain-induced tuning of electronic characteristics, akin…
