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…
Crystal nucleation and near-epitaxial growth in nacre
Ian C. Olson, Adam Z. Blonsky, Nobumichi Tamura +2
Nacre is a layered, iridescent lining found inside many mollusk shells, with a unique brick-and-mortar periodic structure at the sub-micron scale, and remarkable resistance to frac…
Observation of new intrinsic properties of VO2
Bongjin Simon Mun, Kai Chen, Youngchul Leem +8
The single crystal VO2, exihibiting a first-order metal-insulator transition (MIT) at 67.2 degrees C and an insulator-insulator transition (IIT) at ~49.7 degrees C, is grown. From…
The role of point-like topological excitations at criticality: from vortices to global monopoles
Nuno D. Antunes, Luis M. Bettencourt, Martin Kunz
We determine the detailed thermodynamic behavior of vortices in the O(2) scalar model in 2D and of global monopoles in the O(3) model in 3D. We construct new numerical techniques,…
