Welcome to NANOMADE Group
Welcome to the Nano Materials and Devices Group (NANOMADE) webpage of the Centre for Nanotechnology at the Indian Institute of Technology, Roorkee (IITR). We invite you to peruse our website and reach out to us if you are interested in a specific research topic. As a group, we are involved in the research of fundamental aspects of two-dimensional (2D) materials from growth to applications. We dedicate our research to exploring novel 2D materials, perovskites, and other nanomaterials in emerging fields like transistors, photodetectors, solar cells, random lasing, biosensors, flexible and transparent electronics, and other optoelectronic-based applications. We are committed to contributing to the understanding of this growing, diverse, and exciting field of quantum materials. We want to be a reference for the coming generations interested in the fundamental properties of quantum materials and their diverse applications. We also want to inspire young minds to see science as a route to uncovering nature secrets as well as a driving force to improve human life.
