Superconductivity in non-centrosymmetric rhombohedral NbSe2
Zhengxian Li, Xiaoyu Shen, Kai Liu +14
Crystal stacking offers a powerful yet underexplored route to engineer symmetry in layered superconductors. Here we report superconductivity in rhombohedral-stacked NbSe2 (3R-NbSe2…
Roles of Structural Coordination and Strain Orientation in the Phase Stability of Ferroelectric HfO
Adedamola D. Aladese, Xiao Shen
Phase stabilization continues to be a critical issue in hafnium oxide (HfO) due to the interdependence of various contributing factors. Using first-principles calculations, we…
Phosphorus Nanotubes from Chemical Cleavage
Romakanta Bhattarai, Xiao Shen
We propose a strategy to make phosphorus nanotubes from two well-known phosphorus allotropes: violet phosphorus and fibrous red phosphorus. First-principles calculations show that…
Decoupled few-femtosecond phase transitions in vanadium dioxide
Christian Brahms, Lin Zhang, Xiao Shen +11
The nature of the insulator-to-metal phase transition in vanadium dioxide (VO2) is one of the longest-standing problems in condensed-matter physics. Ultrafast spectroscopy has long…
Realization of A Strong Ferroelectric Metal by Nb-doping in Strained EuTiO
Sheng Xu, Yanni Gu, Chuanbo Zheng +1
Ferroelectric (FE) metals have been attracting attention as they possess both metallicity and ferroelectricity, the two seemingly incompatible physical properties. An important pro…
Variability of structural and electronic properties of bulk and monolayer Si2Te3
Yevgeniy Puzyrev, X. Shen, C. Combs +1
Since the emergence of monolayer graphene as a promising two-dimensional material, many other monolayer and few-layer materials have been investigated extensively. An experimental…
