Chirality is a key characteristic in many physical, chemical, and biological systems, profoundly influencing their properties and behaviors in chiral environment. This research specifically focuses on the effects of temperature and crystal structure on chirality in perovskite (PVK) materials, a class of compounds with immense significance in optoelectronics. Besides the crystal phase transfer during film fabrication, the work posits the estimation of second-order nonlinear susceptibility, a critical property in nonlinear optics which encapsulates all pertinent information about the material's chirality for chiral PVK films.
