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…
Stable crack propagation in dislocation-engineered oxide visualized by double cleavage drilled compression test
Oliver Preuß, Zhangtao Li, Enrico Bruder +4
Understanding crack tip - dislocation interaction is critical for improving the fracture resistance of semi-brittle materials like room-temperature plastically deformable ceramics.…
A brief history of dislocations in ceramics: From Steinsalz to quantum wires
Xufei Fang
Dislocations in ceramics have enjoyed a long yet underappreciated research history. This brief historical overview and reflection on the current challenges provides new insights in…
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…
Coupled electromigration-nanoindentation study on dislocation nucleation in SrTiO3
Chukwudalu Okafor, Ahmad Sayyadi-Shahraki, Sebastian Bruns +5
Modern functional oxides are mainly engineered by doping, essentially by tuning the defect chemistry. Recent studies suggest that dislocations offer a new perspective for enhancing…
