Research Projects

The objective of this project is to investigate the latest developments in MXenes, a two-dimensional (2D) material group comprising transition metal carbides, nitrides, and carbonitrides. Due to their exemplary electronic, optical, and electrochemical properties, MXenes have the potential to revolutionize many technological applications, particularly in optoelectronics and energy storage. The unique layered structure, high conductivity, large surface area, and rich surface chemistry of MXenes can be further optimized through surface functionalization, modification of the electronic band structure, and the introduction of defects. Such modifications are crucial for improving performance in both fields. The study examines the impact of surface functional groups (e.g., –OH, –O, –F) on the chemical stability and electronic properties of MXene sheets. The functionalization of the surface is a crucial method for tuning optical absorption and electrical conductivity, which is essential for applications such as photodetectors, transparent electrodes, and other optoelectronic devices. Furthermore, the band structure can be modified through techniques such as doping, thereby achieving optimal electronic properties for a range of applications. The bandgap control is significant in optoelectronics, where the precise electronic and optical behaviour of materials is required. MXenes also show great promise as electrode materials in energy storage devices such as supercapacitors and batteries due to their high ion conductivity and reversible charge storage capabilities. Modifications to MXene surfaces by introducing a spacer layer have been shown to enhance energy density, power delivery and cycle life, making them ideal for next-generation energy storage solutions. The project employs a combination of theoretical modelling, including density functional theory (DFT), and experimental validation, to assess the effects of these modifications on chemical and electronic properties. The potential of tunable MXenes is being explored for flexible and transparent electronics, photodetectors, and sensors, where their optoelectronic properties can be optimized for enhanced performance. This project also highlights the versatility of MXene, demonstrating its potential to drive innovation in energy-efficient devices and high-performance energy storage systems.
