Electronic Material Processing (EMP): Layered Semiconductor Lab, IIT Bombay
The EMP Lab is dedicated to advancing scalable synthesis and defect engineering of 2D layered materials, with a particular focus on wafer-scale TMDC growth, understanding growth mechanisms, and tailoring material properties for optoelectronic applications.
The group also develops advanced research instrumentation in-house, including building MOCVD and inductively coupled plasma (ICP) systems from the ground up, enabling greater flexibility and control over materials synthesis and processing.
