Low-dimensional Electronics Mechanics and Photonics
Our research group explores new schemes to engineer the physical properties of newly discovered two dimensional materials and their heterostructures. By exploiting these new properties, our aim is to configure atomic-scale electronic, photonic and mechanical devices, addressing current technical challenges.
