摘要：Nanoscale materials, especially 2D materials and nanowires, represent a material system that is setting for breakthroughs in fundamental research and transformative technologies. For example, 2D semiconductor with few surface dangling bonds and atomic level uniformity can exhibit excellent optical/electronic properties that are difficult to achieve in other nanostructures. van der Waals (vdW) integrations, one of my major research interests, bring a totally new degree of freedom to nearly arbitrarily combine highly distinct materials, even molecular layers at the atomic scale to create artificial superlattices and functional nanosystem. Chemical integration, a robust and scalable solution, also boosted my research to new level, where, for example, lateral epitaxial heterostructure was realized for the first time. Together, such nanoscale materials, artificial superlattices and heterostructures serve as an excitingfrontier for exploring fundamental physics, materials science and device engineering. It can offer exciting opportunities to control the generation, confinement, and transport of charges, excitons, photons and phonons at the level of single atom thickness and have the potential to open up technological opportunities beyond the reach of traditional materials to allow special advances across diverse areas ranging from traditionalelectronics, optoelectronics, energy storage to the emerging areas of bio-integrated electronics, plasmonic devices, spintronic devices and quantum computing.
