Metal-halide perovskites (MHP) stand out as highly promising and cost-effective optoelectronic materials due to their exceptional optoelectronic properties and versatile fabrication methods [1-6]. These materials find applications in diverse fields such as solar cells, light-emitting diodes, photodetectors, and even quantum emitters. Quantum confinement can unveil unexpected and advantageous characteristics, leading to the development of high-performance devices.
One approach to induce quantum confinement involves creating layers of quantum-confined materials through the deposition of multiple thin films. [7-10] Thermal evaporation emerges as a particularly promising technique for fabricating halide perovskite films, offering precise control over layer thickness, fine-tuning of composition, stress-free film deposition, and the ability to modify surface properties. The use of thermal evaporation in perovskite fabrication has expanded the possibilities of thin film production, showcasing its capability to generate ultrathin perovskite films that serve as the foundation for multi-quantum well structures.[11]
This method enables the manipulation of growth properties, influencing the optoelectronic characteristics of nanoscale thin films and inducing quantum confinement effects within the structure. The precise control over photoluminescence through quantum confinement opens up a wide array of possibilities for unconventional optoelectronic properties and novel applications of perovskites.
