Describing the diverse geometries of gold from nanoclusters to bulk-- a first-principles based hybrid bond order potential
Badri Narayanan, Alper Kinaci, Fatih G. Sen +4
Molecular dynamics simulations using empirical force fields (EFFs) are crucial for gaining fundamental insights into atomic structure and long timescale dynamics of Au nanoclusters…
Origin of the turn-on temperature behavior in WTe
Y. L. Wang, L. R. Thoutam, Z. L. Xiao +8
A hallmark of materials with extremely large magnetoresistance (XMR) is the transformative 'turn-on' temperature behavior: when the applied magnetic field is above certain valu…
Temperature dependent three-dimensional anisotropy of the magnetoresistance in WTe
L. R. Thoutam, Y. L. Wang, Z. L. Xiao +5
Extremely large magnetoresistance (XMR) was recently discovered in WTe, triggering extensive research on this material regarding the XMR origin. Since WTe is a layered comp…
Stabilization of highly polar BiFeO-like structure: a new interface design route for enhanced ferroelectricity in artificial perovskite superlattices
Hongwei Wang, Jianguo Wen, Dean J. Miller +5
In ABO3 perovskites, oxygen octahedron rotations are common structural distortions that can promote large ferroelectricity in BiFeO3 with an R3c structure [1], but suppress ferroel…
Silicon-nitride photonic circuits interfaced with monolayer MoS
Guohua Wei, Teodor K. Stanev, David A. Czaplewski +2
We report on the integration of monolayer molybdenum disulphide with silicon nitride microresonators assembled by visco-elastic layer transfer techniques. Evanescent coupling from…
High resolution three dimensional structural microscopy by single angle Bragg ptychography
S. O. Hruszkewycz, M. Allain, M. V. Holt +4
We present an efficient method of imaging 3D nanoscale lattice behavior and strain fields in crystalline materials with a new methodology -- three dimensional Bragg projection ptyc…
