Data from: A hybrid organic-inorganic perovskite dataset
Hybrid organic-inorganic perovskites (HOIPs) have been attracting a great deal of attention due to their versatility of electronic properties and fabrication methods. We prepare a dataset of 1,346 HOIPs, which features 16 organic cations, 3 group-IV cations and 4 halide anions. Using a combination of an atomic structure search method and density functional theory calculations, the optimized structures, the bandgap, the dielectric constant, and the relative energies of the HOIPs are uniformly prepared and validated by comparing with relevant experimental and/or theoretical data. We make the dataset available at Dryad Digital Repository, NoMaD Repository, and Khazana Repository (http://khazana.uconn.edu/), hoping that it could be useful for future data-mining efforts that can explore possible structure-property relationships and phenomenological models. Progressive extension of the dataset is expected as new organic cations become appropriate within the HOIP framework, and as additional properties are calculated for the new compounds found.

Bandgap Pressure Coefficient of a CH3NH3PbI3 Thin Film Perovskite
<p>This work shows experimental and theoretical studies of the pressure-induced evolution of the electronic structure of the orthogonal phase (OP) of MAPbI3. We have shown that the bandgap of the MAPbI3 in OP can be tuned in a broader range of pressure (≲3.5 GPa) when compared to the tetragonal phase (TP), in which a red-shift of PL peak is observed only up to ∼0.3 GPa. Such behavior results from the better stability of the crystal lattice against octahedral distortions in the low-temperature regime due to the reduced phonon contribution and different Pb−I bond geometry. We found the pressure coefficient of the OP to be negative and dependent on the temperature. A negative deformation potential results from the antibonding character of the bottom of the conduction band and the top of the valence band, while dependence on the temperature can be explained by changes in the unit cell volume and geometry as the atomic configuration approaches the temperature-induced phase transition as well as phonon contribution. On the whole, our results advance the understanding of the behavior of the low-temperature MAPbI3 phase under extreme conditions and show that hydrostatic pressure allows fine-tuning of structural and optical properties, resulting in the possibility of realizing materials with the desired properties for technological applications.</p>
