Investigation of optical and electrical properties of GA/GZ/PbI2 and GA/GZ/PbI2/B nanocomposites

Abstract

To introduce a suitable functional composite for electronic and optical applications, different structures of Graphene, Lead iodine and Borophene layers were studied using density functional theory (DFT). Band structures, the density of state, the projected density of state, the joint density of state, extinction index, normal incidence reflectivity, refractive index, and Electron Energy Loss Spectroscopy were calculated for these structures. Based on these the results, improving the optical absorption in the visible region and changing the population of free charge carriers obtained make made Graphene/Graphene/Lead Iodine (GA/GZ/PbI2), and Graphene/Graphene/Lead Iodine/Borophene (GA/GZ/PbI2/B) nanocomposites a suitable promising new composites for manufacturing and designing new novel light-sensitive nanoscale devices.
