Uniformly Distributed Heteroatoms Containing Two-Dimensional Networks

Abstract

Two-dimensional (2D) networks with uniformly decorated heteroatoms attract immense interest beyond graphene due to their multifunctionality such as unusual electronic, optoelectronic, magnetic and electrocatalytic properties. Despite recent explorations in 2D networks science and engineering, easy and scalable methods to produce 2D networks with uniformly decorated heteroatoms are limited. To overcome these problems, a new layered 2D network structures with uniformly distributed holes and/or nitrogen atoms were synthesized and their stoichiometry of basal plane is C2N and/or C3N.1,2 Their structures were confirmed by scanning tunneling microscopy (STM). Their electronic properties were studied by density-functional theory (DFT) calculations and electrooptical measurements.
