## Abstract

Metal halide perovskites
(MHPs) have emerged as a class of highly
efficient semiconductor materials, attracting widespread interest
for their potential applications in photovoltaics, light-emitting
diodes, photodetectors, and transistors. Vapor-phase techniques for
perovskite synthesis represent a paradigm shift in materials processing,
offering precise control over morphology, crystallinity, and composition,
while enabling industry-scale manufacturing. This review highlights
advancements in vapor-phase synthesis of MHP thin films and micro-
and nanostructures, emphasizing strategies to enhance electronic and
optical properties, with structural control for next-generation device
integration. We introducethe fundamental principles of widely used
vapor-phase growth methods and discuss key process modifications employed
to control chemical composition, crystal dimension, anisotropic growth,
doping, phase purity, and substrate compatibility. We also summarize
notable device performance, underscoring the transformative potential
of vapor-phase approaches for scalable and high-performance optoelectronic
technologies with MHPs.
