Site preference of chalcogen atoms in 1T ( Mo and W; S, Se, and Te)
Shota Ono, Ryotaro Ohse
The insulator-metal transition, accompanying the structural phase transition from 2H to 1T structure, has been reported in two-dimensional W-S-Te and W-Se-Te systems. It i…
Hidden layered structures from carbon-analog metastability in metal dichalcogenides
Shota Ono
Carbon exhibits both a layered ground state structure that produces two-dimensional (2D) nanosheets and a non-layered diamond structure created under high pressure conditions. Moti…
A Framework for Identifying Non-van der Waals 2D Materials
Shota Ono
Two-dimensional (2D) materials are categorized into van der Waals (vdW) and non-vdW types. However, no relevant descriptors have been proposed for identifying the latter. Here, we…
Composition-dependent ultrafast luminescence in Cu-Ni alloys: Combined experimental and ab initio study
Tohru Suemoto, Haruki Morino, Shota Ono +5
Properties of Cu-Ni solid solutions have long been studied in physical and materials sciences. Yet, their many-body properties have not been well understood. Here, we investigate u…
Breakdown of continuum elasticity due to electronic effects in gold nanotubes
Shota Ono, Hideo Yoshioka
A recent experiment reports a creation of goldene, which is two-dimensional gold with hexagonal structure. By rolling up the goldene, gold nanotubes (GNT) should exist, but their s…
