United KingdomThis research explores the stabilization of tin (Sn²⁺) halide perovskites, a class of materials known for their potential in creating efficient, lead-free semiconductors. These materials offer advantages such as efficient charge transport and chemical tunability, making them suitable for applications like solar cells and transistors. However, their inherent chemical 'softness' causes issues like spontaneous self-doping and rapid degradation due to reactive surface sites. To address this, researchers introduced a method involving acetate vapor, which temporarily interacts with unstable tin sites before evaporating during heat treatment. This process promotes a surface reconstruction that reduces reactivity and enhances stability. The resulting material allows for the creation of transistors with improved reliability and longevity, functioning stably even at elevated temperatures for extended periods.
