Tunable topology and berry curvature dipole in transition metal dichalcogenide Janus monolayers

open access: yesMaterials Research Express, 2021
Janus transition metal dichalcogenides, with intrinsic mirror asymmetry, exhibit a wide array of interesting properties. In this work, we study Janus monolayers derived from WTe _2 using first-principles and tight-binding calculations.

Crystal Structure and Chemistry of Topological Insulators

open access: yes, 2013
Topological surface states, a new kind of electronic state of matter, have recently been observed on the cleaved surfaces of crystals of a handful of small band gap semiconductors.

Determination of ferroelectric compositional phase transition using novel virtual crystal approach [PDF]

open access: yes, 2000
We employ a new method for studying compositionally disordered ferroelectric oxides. This method is based on the virtual crystal approximation (VCA), in which two or more component potentials are averaged into a composite atomic potential. In our method,

Combinatorial selection of molecular conformations and supramolecular synthons in quercetin cocrystal landscapes: a route to ternary solids

open access: yesIUCrJ, 2015
The crystallization of 28 binary and ternary cocrystals of quercetin with dibasic coformers is analyzed in terms of a combinatorial selection from a solution of preferred molecular conformations and supramolecular synthons.
