AoE 2D Materials Research
  • Two-dimensional (2D) materials have a great potential for microelectronics and information technology. The variety of 2D materials feature a wide range of material properties from metal, semiconductors, insulators to magnets and superconductors, as well as exotic physics associated with electrons' quantum degrees of freedom (e.g. spin and valley) that could be exploited to encode and process information efficiently. Their tiny thickness - just a few atoms - promises the ultimate miniaturization of devices, and unparalleled control of materials and device functions. Moreover, 2D materials feature an unprecedented flexibility in their assembly into heterostructures, through which new materials and device functionalities may emerge. This project brings together leading physicists, engineers, and chemists on 2D materials research, to explore new opportunities and tackle grand challenges in a number of areas from fundamental science to technological applications in electronics, optoelectronics and photonics. The topics and interactions of this interdisciplinary project are illustrated below.
