The Rise of 2D Halide Perovskites

Two-dimensional halide perovskites (2D-HaP) are a sub-class of 3D perovskites, which have emerged as a new class of solution-processed organic-inorganic (hybrid) low-dimensional semiconductors. They imbibe their properties from four exciting classes of novel materials - quantum wells, atomically thin 2D materials, organic semiconductors, and 3D halide perovskites. There is growing consensus that their physical properties are dictated by the interaction between the organic cation and the inorganic framework, which presents a unique opportunity to tailor their behaviours. Moreover, the 2D-HaPs have demonstrated technologically relevant durability in contrast to the 3D-HaPs and combining them with 3D perovskites has demonstrated the path for overcoming the issue of long-term durability in halide perovskite-based optoelectronic devices.

In this talk I will describe our work over the past five years on 2D-HaPs ranging from the fundamental light-induced structural behaviors, solvation dynamics to control homogeneity of layer thickness, novel photo-physical behaviors, charge transport and their role in high-efficiency optoelectronic device, with technologically relevant durability. I will also present key challenges and opportunities, which highlights the complex and rich materials chemistry, physics and engineering, which are at the root of 2D-HaP semiconductors and if resolved would lead to low-cost, technologies that shape our future.

 

About Aditya D. Mohite

Aditya D. Mohite is an associate professor in the Department of Chemical and Biomolecular Engineering at Rice University and directs an energy and optoelectronic devices lab working on understanding structure-function properties in materials with the aim of controlling charge and energy flow across. His research philosophy is applying creative and out-of-the-box approaches to solve fundamental scientific bottlenecks and they utilize the knowledge to demonstrate technologically relevant performance in devices that is on par or exceeds the current state-of-the-art devices. A key mission of his group is to advance the knowledge of knowledge of materials, chemistry, physics, and engineering to develop next-generation technologies by working with a multidisciplinary and diverse group with emphasis on partnering with institutes and individuals, which support underrepresented minorities through research and education.

He has published 160 peer reviewed papers in journals such as Science, Nature, Nature Materials, Nature Nanotechnology, Nano Letters, ACS Nano, Chemical Society Reviews, Applied Physics Letters and Advanced Materials amongst others. He has also delivered more than 90 invited talks.
