The interest in two dimensional (2D) materials is rapidly spreading across all scientific and engineering disciplines due to their exceptional properties, which not only provide a platform to investigate intriguing physical phenomena but also promise solutions to the most relevant technological challenges. It is undisputed that silicon has been the DNA of our technological evolution for the last several decades. However, with the emergence of the era of Internet of Things (IoT), novel materials need to be mutated into the genetics of the modern technologies in order to meet the ever increasing demand of new functionalities. In this context, the 2D layered materials like MoS2, WSe2, Black Phosphorus, Graphene and many more find their application in flexible electronics, self-powered electronics, advance optoelectronics, neural electronics as well as digital electronics. In fact, field effect transistors, gas sensors, bio-detectors, mechanical resonators, optical modulators and energy harvesting devices with superior performances have already been demonstrated based on different 2D materials. A major challenge towards the commercialization of 2D materials is the large area, scalable and controllable growth of highly crystalline monolayers in a cost effective way. In this context, chemical vapor deposition, liquid phase exfoliation and electrochemical synthesis approaches are showing a lot of promise. My talk will provide a holistic understanding of 2D materials starting from large area synthesis to device fabrication to different electronic and optoelectronic applications.
