The Role of Polymers in Halide Perovskite Resistive Switching Devices

Abstract

Currently, halide perovskites (HPs) are gaining traction in multiple applications, such as photovoltaics and resistive switching (RS) devices. In RS devices, the high electrical conductivity, tunable bandgap, good stability, and low-cost synthesis and processing make HPs promising as active layers. Additionally, the use of polymers in improving the RS properties of lead (Pb) and Pb-free HP devices was described in several recent reports. Thus, this review explored the in-depth role of polymers in optimizing HP RS devices. In this review, the effect of polymers on the ON/OFF ratio, retention, and endurance properties was successfully investigated. The polymers were discovered to be commonly utilized as passivation layers, charge transfer enhancement, and composite materials. Hence, further HP RS improvement integrated with polymers revealed promising approaches to delivering efficient memory devices. Based on the review, detailed insights into the significance of polymers in producing high-performance RS device technology were effectively understood.

Implementation of Stable Nonvolatile Resistive Switching Behaviors in TiO2 Nanoparticle‐Incorporated 2D Layered Halide Perovskite‐Based Devices

“…As known that the activation energy of halide vacancies in organic–inorganic halide perovskite materials is relatively low, and as a result, the halide vacancies are the main type of vacancy defects. [ 40 ] In addition, plenty of oxygen vacancies are also existing on the surface of TiO 2 nanoparticles. Therefore, it is supposed that the bromine/oxygen ion migration and the subsequently accompanying introduced iodine/oxygen vacancies are the factor for RS behaviors in Al/TiO 2 –PEA 2 PbBr 4 /ITO memories.…”

The interaction between Pb 2 + ions and the electrons from the ether oxygen in PEO helps in forming a host medium for the Pb 2 + cations, thereby allowing redox reaction based write-once-read-many times resistive switching behavior.…”
