Dislocation-point defect interaction on plasticity across the length scale in SrTiO3
Chukwudalu Okafor, Kohei Takahara, Svetlana Korneychuk +7
Point defect engineering is widely used to tailor the electronic and transport properties of complex oxides, yet its influence on dislocation plasticity remains poorly understood.…
Dislocation interaction with a tilt low angle grain boundary in bi-crystal SrTiO3
Kuan Ding, Atsutomo Nakamura, Patrick Cordier +1
For potentially wider applications of ceramics with dislocation-tuned mechanical and functional properties, it is pertinent to achieve dislocation engineering in polycrystalline ce…
Effective reduction in thermal conductivity by high-density dislocations in SrTiO3
Jinxue Ding, Jiawen Zhang, Jinfeng Dong +5
Decreasing thermal conductivity is important for designing efficient thermoelectric devices. Traditional engineering strategies have focused on point defects and interface design.…
Room-temperature dislocation plasticity in ceramics: Methods, Materials, and Mechanisms
Alexander Frisch, Chukwudalu Okafor, Oliver Preuà +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…
Harvesting room-temperature plasticity in ceramics by mechanically seeded dislocations
Xufei Fang, Wenjun Lu, Jiawen Zhang +7
The quest for room-temperature ductile ceramics has been repeatedly fueled by hopes for large-scale applications but so far has been not successful. Recent demonstrations of enhanc…
