This article examines the relative stability of the Pnma, Cmcm, rocksalt and pi-Cubic phases of the tin chalcogenides SnS and SnSe with respect to pressure and temperature. This repository makes available raw data from these calculations, including:
* Quasi-harmonic phonon calculations and derived finite-temperature properties;
* Transition-state searches between the rocksalt and pi-Cubic phases using the nudged elastic-band (NEB) method; and
* Electronic density of states (DoS) and band structures.
