2D Materials and Devices Group

Welcome to the 2D Materials and Devices Homepage!

We're a research group based in the Department of Materials Science and Metallurgy at the University of Cambridge. Our research deals with the fundamental aspects of two-dimensional materials synthesized by chemical exfoliation and chemical vapor deposition. We research a variety of topics ranging from phase engineering of 2D materials, low resistance electrical contacts on 2D semiconductors for high performance electronics, metallic 2D materials for energy storage and electrocatalysis, interfaces between 3D complex oxides and 2D, and chemical functionalization of 2D materials.

Research areas


Our research explores atomically thin 2D materials for energy efficient devices in next generation information and communication technologies. We are particularly interested in achieving ideal contacts to 2D semiconductors that would help reap the benefits of short channel devices. Our demonstration of phase engineered contacts in 2D Transition metal dichalcogenides and van der Waals contacts between metals and monolayer semiconductors have been key milestones in this direction. We are currently using these ideal contacts to improve the injection of carriers (both charge and spin) in devices that rely on tunneling, for both logic and memory devices. We are also interested in understanding the fundamental mechanisms by which 2D materials interact with functional oxides where interfacial coupling between various degrees of freedom could lead to quantum electronic and optical phenomena.



We work across the LiSTAR (Lithium-Sulfur Technology Accelerator) project of Faraday Institution, UK’s flagship battery research programme aiming to place the UK at the forefront of the global battery revolution. The project is a collaboration of seven university and eight industrial partners, each bringing unique capabilities to the development of Li-S batteries. We contribute to the cathode material design and pouch cell manufacturing technologies to produce high-performance practical Li-S batteries. We also work on solid-state electrolytes and Na-ion batteries.



Engineered 2D Transition Metal Dichalcogenides (TMDs) are highly active and affordable electrocatalysts that could significantly contribute to the widespread implementation of green hydrogen and other clean technologies. For instance, redox flow batteries, electrolyzers and fuel cells. Our material discovery methodology relies on finely tuning the structure, composition, and dimensions of different TMDs and composite materials as a viable tool to modulate substrate/catalyst interaction and associated catalytic activity. Among different reactions, we pay emphasis to new materials and testing methods to accelerate reactions including hydrogen evolution and oxidation, oxygen evolution and reduction, CO2 reduction or the electrosynthesis of ammonia via nitrogen activation.

Latest Happenings in the 2DMD Sphere

2DMD Members at the 2D Transition Metal Dichalcogenides Conference 2024

The 2DTMD Conference presents the latest developments in synthesis of 2D TMDs and their implementation in electronics, photonics, catalysis, as well as energy conversion and storage. Glad to have Prof. Manish Chhowalla as the Organizing Chair and several of our group members present at the Conference in Hong Kong!

Seminar by Professor Young Duck Kim

Glad to have Professor Young Duck Kim from Kyung Hee University give a talk on “Hexagonal boron nitride for quantum light emission and Moire remote doping”! Prof. Kim presented the deep ultraviolet (DUV) electroluminescence from hBN heterostructures and the creation of robust carbon color centers in hBN under an applied local electric field. Electrically induced carbon color centers in hBN play an important role in developing efficient solid-state DUV light sources and deterministic quantum emitters.
