Monolithic Expandable-FOV Metalens Enabled by Radially Gradient-Tilted Meta-Atoms
Feiyang Zhang, Guoxia Han, Yihan Tian +3
Metalens, as the most promising and applicable emerging optical device, has long been constrained by the limited field of view (FOV). Recent studies employing phase engineering or…
High-pressure structures and superconductivity of bismuth hydrides
Yanbin Ma, Defang Duan, Da Li +7
We have systematically searched for the ground state structures of bismuth hydrides based on evolutionary algorithm method and particle swarm optimization algorithm method. Given o…
The unexpected binding and superconductivity in SbH4 at high pressure
Yanbin Ma, Defang Duan, Da Li +7
The semimetal antimony (Sb) element doped into hydrogen has been performed theoretically to explored high-pressure crystal structure and superconductivity of antimony hydrides. The…
Pressure-induced decomposition of solid hydrogen sulfide
Defang Duan, Xiaoli Huang, Fubo Tian +7
Solid hydrogen sulfide is well known as a typical molecular crystal but its stability under pressure is still under debate. Particularly, Eremets et al. found the high pressure sup…
Decomposition of solid hydrogen bromide at high pressure
Defang Duan, Fubo Tian, Xiaoli Huang +6
The stability of different stoichiometric HBr (=1-7) compounds under pressure are extensively studied using density functional theory calculations. Five new energetically st…
