A solid-solution approach for room-temperature bulk plasticity in KTa1-xNbxO3
Alexander Frisch, Jiawen Zhang, Martin Setvin +3
Dislocations are being engineered into perovskite oxides to harvest versatile functional properties. One major bottleneck, however, persists: perovskite oxides that can be engineer…
Scale-bridging dislocation plasticity in MgO at room temperature
Jiawen Zhang, Zhangtao Li, Yuwei Zhang +7
Dislocations in ceramics have recently gained renewed research interest, in contrast to the traditional belief that ceramics are inherently brittle. Understanding dislocation mecha…
Toughening beta-Ga2O3 via mechanically seeded dislocations
Zanlin Cheng, Jiawen Zhang, Peng Gao +3
\b{eta}-Ga2O3 is a promising candidate for next-generation semiconductors, but is limited by its intrinsic brittleness, which hinders its application in flexible electronics and hi…
Dislocation-enhanced piezoelectric catalysis of KNbO3 crystal for water splitting
Hanyu Gong, Jiawen Zhang, Yan Zhao +6
Dislocations in oxides with ionic/covalent bonding hold the potential of harnessing versatile functionalities. Here, high-density dislocations in a large plastic zone in potassium…
Room-temperature dislocation plasticity in ceramics: Methods, Materials, and Mechanisms
Alexander Frisch, Chukwudalu Okafor, Oliver Preuß +5
Dislocation-mediated plastic deformation in ceramic materials has sparked renewed research interest due to the technological potential of dislocations. Despite the long research hi…
Impact of dislocation densities on the microscale strength of single-crystal strontium titanate
Jiawen Zhang, Xufei Fang, Wenjun Lu
Dislocations in ceramics at room temperature are attracting increasing research interest. Dislocations may bring a new perspective for tuning physical and mechanical properties in…
