Abstract: Abstract Vanadium pentoxide (V2O5) exhibits an unusual lattice symmetry (orthorhombic crystal). The theoretical framework based on the first-principles calculations is utilized to investigate the essential properties of the V2O5 compound. The complete picture of multi-hybridization… read more here.

DOI: 10.1103/physrevb.101.205409
Abstract: Optically generated excitons dictate the absorption and emission spectrum of doped semiconductor transition-metal dichalcogenide monolayers. We show that upon increasing the electron density, the elementary optical excitations develop a rotonlike dispersion, evidenced by a shift… read more here.
