Through experimental and theoretical approaches, we seek to advance knowledge of van der Waals heterostructures and their potential for innovative applications in materials science.

Twistronics

Our research interest in twistronics focuses on the unique properties of bilayer and multilayer materials, especially graphene, TMDs and h-BN when twisted at specific angles. This twisting can lead to exotic electronic behaviors, such as superconductivity and correlated insulator states. We aim to investigate how twist angles affect electronic band structures and interlayer interactions, which could unveil new phases of matter and drive innovations in quantum materials. Additionally, we seek to develop novel devices that leverage these unique properties for applications in advanced electronics and quantum computing.

Blue Energy

Keeping eye on future energy demand, our research focuses on blue energy, derived from the salinity gradient between freshwater and saltwater, as a sustainable energy source. We investigate technologies for blue energy harvesting such as pressure retarded osmosis (PRO) and reverse electro dialysis (RED), aiming to optimize their efficiency and scalability through advanced materials and membrane technologies. Additionally, we explore the environmental impacts and economic feasibility of implementing blue energy solutions in coastal areas. By promoting interdisciplinary collaboration and innovative methodologies, we seek to advance blue energy technologies and contribute to sustainable energy solutions that address climate change and energy security challenges.

Thermoelectrics

Our group focuses on layered 2D materials such as transition metal dichalcogenides, IVA–VIA compounds and Topological Insulators for potential thermoelectric materials by optimizing performance through interface and band structure engineering. We estimate thermal conductivity using the optothermal Raman technique, which is a not contact approach enabling reliable determination of thermal conductivity in 2D systems. We also consider the sustainability and economic viability of integrating these innovative materials into existing energy systems.
