Exploiting Metal-Halide Perovskites Thermal Evaporation for Device Customization and Quantum Confinement

Metal-halide perovskites (MHP) have emerged as highly promising optoelectronic materials due to their exceptional properties and versatile fabrication methods [1-6]. These materials are crucial in applications ranging from solar cells to quantum emitters, harnessing quantum confinement to unlock unique device functionalities.<br/>Thermal evaporation represents a robust technique for depositing halide perovskite films, offering precise control over layer thickness, composition tuning, stress-free deposition, and surface modification capabilities. This method has revolutionized thin film production by enabling the creation of ultrathin perovskite layers, forming the basis for constructing multi-quantum well structures.<br/>By manipulating growth parameters, thermal evaporation influences the optoelectronic properties of nanoscale thin films, leveraging quantum confinement effects to precisely control photoluminescence characteristics. This capability opens avenues for unconventional optoelectronic functionalities and novel perovskite applications [7-10].<br/>References:<br/>J. Li et al., Joule 2020, 4, 1035<br/>H.A.
