Welcome to Kausik Majumdar’s research group at the Department of Electrical Communication Engineering at Indian Institute of Science. We use a combination of theoretical and experimental techniques to investigate the electrical and optoelectronic properties of low dimensional materials and their nanostructures. We are also equally interested in applying these fascinating properties to develop novel devices, encompassing the entire spectrum of device design and simulation, device fabrication using state of the art semiconductor fabrication techniques, and device characterization using various electrical, optical and spectroscopic techniques.
