Type-I Heterostructure and Improved Phase Stability of Formamidinium Lead Iodide Perovskite Grown on WS_2

Abstract: Heterostructures of two-dimensional materials provide an opportunity for the discovery of novel properties and improved material performances. In this work, we demonstrate the chemical vapor deposition growth of two-dimensional perovskite/WS2 heterostructures. Owing to type-I band alignment, photoluminescence (PL) measurements indicated the photogenerated carrier transfer from the WS2 to the perovskite layer. In order to investigate the carrier transfer mechanism, power-dependent PL spectra were measured. The … Show more

“…Heterostructures are essential elements in the modern semiconductor industry and play a crucial role in high-speed electronics and optoelectronic devices. [251][252][253][254][255][256] This wide range of applications stem from the tunable band alignment which enables electron and hole transfer across the heterojunction. TMD-based heterostructures consist of vertical van der Waals and lateral heterostructures.…”
