Antimony trisulfide has a proper bandgap of 1.7 eV for making solar cells but the devices suffer from severe voltage loss. Here Yang et al. propose that the photoexcited carriers are self-trapped by lattice deformation, which places a thermodynamic l

Application of the nonadiabatic molecular dynamics (NAMD) approach is severely limited to studying carrier dynamics in the momentum space, since a supercell is required to sample the phonon excitation and electron-phonon (e-ph) interaction at differe

The anisotropic transport properties of gallium telluride (GaTe) have been reported by several experiments, giving rise to many debates recently. The anisotropic electronic band structure of GaTe shows the extreme difference between the flat band and

Tin selenide, a thermoelectric semiconductor, has gained attention for its high thermoelectric efficiency. Time-resolved angle-resolved photoemission spectroscopy reveals longer hot carrier lifetimes at the conduction band minimum than at the Γ poin

Antimony trisulfide (Sb2S3) is considered to be a promising photovoltaic material; however, the performance is yet to be satisfactory. Poor power conversion efficiency and large open circuit voltage loss have been usually ascribed to interface and bu

Photogenerated charge carrier dynamics at the WSe2/hBN van der Waals interface play an important role in optical device applications. The carrier behavior has been argued to be related to the interlayer phonon–phonon interaction in the heterostruct
