Stress Induced Structural Transformations in Au Nanocrystals
Abhinav Parakh, Sangryun Lee, Mehrdad T. Kiani +5
Nanocrystals can exist in multiply twinned structures like the icosahedron, or single crystalline structures like the cuboctahedron or Wulff-polyhedron. Structural transformation b…

Nucleation of Dislocations in 3.9 nm Nanocrystals at High Pressure
Abhinav Parakh, Sangryun Lee, K. Anika Harkins +7
As circuitry approaches single nanometer length scales, it is important to predict the stability of metals at these scales. The behavior of metals at larger scales can be predicted…

Anharmonicity-induced isostructural phase transition of Zirconium under pressure
Elissaios Stavrou, Lin H. Yang, Per Soderlind +8
We have performed a detailed x-ray diffraction structural study of Zr under pressure and unambiguously identify the existence of a first-order isostructural bcc-to-bcc phase transi…
