Key Points

This research aims to explore the phase transitions in MASnI₃ under varying pressure and temperature conditions.
Utilized in situ synchrotron XRD analysis to observe structural changes in MASnI₃.
Focused on the tetragonal-to-orthorhombic II transformation.
Observed a significant phase transition from tetragonal to orthorhombic II.
Detected local structural distortion and evolution of short-range order during the transition.

Implication

Examines phase transitions and optoelectronic characteristics in hybrid perovskite MASnI₃, suggesting enhanced properties.

Abstract

Pressure- and temperature-driven phase transitions in MASnI₃ were revealed by in situ synchrotron XRD analysis, showing a tetragonal-to-orthorhombic II transformation accompanied by local structural distortion and short-range order evolution.
