Efficient Up-Conversion in CsPbBr3 Nanocrystals via Phonon-Driven Exciton-Polaron Formation
Abdullah S. Abbas, Beiye C. Li, Richard D. Schaller +4
Lead halide perovskite nanocrystals demonstrate efficient up-conversion, although the precise mechanism remains a subject of active research. This study utilizes steady-state and t…
Assessing the stability fields of molecular and polymeric CO2
Alexander F. Goncharov, Elena Bykova, Maxim Bykov +4
We investigated the stability of polymeric CO2 over a wide range of pressures, temperatures, and chemical environments. We find that the I-42d polymeric structure, consisting of a…
Phase transition kinetics revealed by in situ X-ray diffraction in laser-heated dynamic diamond anvil cells
Matthew Ricks, Arianna E. Gleason, Francesca Miozzi +7
We report on a novel approach to dynamic compression of materials that bridges the gap between previous static- and dynamic- compression techniques, allowing to explore a wide rang…
Structural evolution of iodine on approach to the monatomic state
Elena Bykova, Iskander G. Batyrev, Maxim Bykov +4
We applied single-crystal X-ray diffraction and Raman spectroscopy in a diamond anvil cell up to 36 GPa and first principles theoretical calculations to study the molecular dissoci…
Synthesis of Ultra-Incompressible Carbon Nitrides Featuring Three-Dimensional Frameworks of CN4 Tetrahedra Recoverable at Ambient Conditions
Dominique Laniel, Florian Trybel, Andrey Aslandukov +22
More than thirty years ago, carbon nitrides featuring 3D frameworks of tetrahedral CN4 units were identified as one of the great aspirations of materials science, expected to have…
High-Pressure Na3(N2)4, Ca3(N2)4, Sr3(N2)4, and Ba(N2)3 Featuring Nitrogen Dimers with Non-Integer Charges and Anion-Driven Metallicity
Dominique Laniel, Bjoern Winkler, Timofey Fedotenko +12
Charged nitrogen dimers are ubiquitous in high-pressure binary metal-nitrogen systems. They are known to possess integer formal charges x varying from one through four. Here, we pr…
