ABSTRACT
This talk focuses on laser-based methods to create 2D materials, such as graphene (G), graphene oxide (GO), reduced graphene oxide (r-GO), h-BN, Q-carbon and diamond related materials. Nanosecond pulsed laser annealing is used to convert amorphous carbon into G, GO, and r-GO, and amorphous BN into h-BN in a control way with a high degree of spatial temporal selectivity. Amorphous carbon layers can be also converted into diamond and Q-carbon depending upon the degree of undercooling before quenching. This approach can be used to selectively dope and write p-n junctions for next-generation of solid state devices. |
