Research Assistant Professor
Welcome to our webpage on Laboratory of 2D Materials and Nanocomposites (2DMN) Research Group. Our Lab focus is to develop scalable, sustainable production methods and processing techniques for nanomaterials with an emphasis to develop novel, energy efficient and cost-effective approaches for fundamentally and commercially useful low dimensional materials such as two-dimensional materials (Graphene, Transition Metal Dichalcogenides, black phosphorus), 1D/3D nanomaterials and their hybrids for a variety of applications. Our specific target is to achieve property enhancement and devices made from dispersions for a plethora of applications. We do an extensive study in production and characterization of exfoliated graphene and other 2D materials for estimating the quality of the nanosheets produced and their physical properties.
Dr. V. Eswaraiah joined SRM Research Institute and Department of Physics and Nanotechnology as an Assistant Professor of Research in SRM Institute of Science and Technology (formerly known as SRM University), Kattankulathur campus since August 2017. We develop energy efficient production and innovative processing techniques for low-dimensional materials especially 2D materials which find applications in sensing, printed electronics, composites, thermal and electronics applications. We have contributed key findings in graphene production and processing techniques in this emerging area of research and co-inventor of three inventions in the area of graphene and strain sensor nanocomposites. His current interest is in high yield production in 2D materials and design of devices using low dimensional materials for nanocomposites, energy and electronic applications.

My group working on two-dimensional nanosheets and interfaces mainly focused on the sustainable and scalable manufacturing of these emerging materials for fundamental and technological applications. We study the processing methodologies for the production of nanosheets in a liquid and solid form in detail to understand the quality and economy of production which has a path for technology transfer. For this approach, we employ various methods and variety of characterization techniques such as electron microscopy, probe microscopy, spectroscopy, electrical, mechanical and thermal characterization techniques to evaluate the quality of the 2D nanosheets we produce and their physical properties. In the end, we demonstrate applications of graphene and other 2D materials such as in composites, printed electronics, sensors, energy storage and conversion devices.
