Abstract:
When the spatial scale goes down from macroscale to nanoscale, temporal scale will reduce to nano to femtosecond, and more importantly, the related energy scale of an externally applied field will drop for eighteen orders from joule to attojoule (1 nN times 1 nm = 6.42 eV), falling into the energy scale of the local fields of matter which consist of electronic structures, charge, molecular orbital and spin states. Therefore, at nanoscale, matters will show distinctly different performances from their bulk materials mainly due to the strong coupling between the local fields of matter and external applied fields, turning common materials such as carbon, even insulators, into functional nanomaterials with exceptional properties we expected for nanoelectronics, spintronics as well as energy conversion devices. In this talk, I will demonstrate by our recent findings (i) such exceptional functional properties in graphene, h-BN, transition metal dichalcogenides, black phosphorous and boron nanofilms; (ii) fabrication of two-dimensional materials and their one- and three- dimensional derivates by merging top-down and bottom-up methodology; (iii) their applications for sensors and generators.
