Improving Phase Stability of α-CsPbI3 through Combined Strain-Doping Engineering: Insights from First-Principles Calculations and Machine Learning
{{output}}
The all-inorganic perovskite of cubic CsPbI3 (α-CsPbI3) exhibited high thermal stability, owing to the absence of volatile organic cations. However, the poor phase stability at room temperature limits its practical applications. In this work, the phase transi... ...
