Abstract
This application relates to monolayers of Si2BN or C2BN, arranged in a graphiticized hexagonal arrangement. Each Si/C atom has a Si/C, B, and N nearest neighbor, while each B (N) has two Si/C's and one N (B) as nearest neighbors. The monolayer can be a 2D composition or can be “rolled” into a nanotubular 3D arm-chair or zig-zag configuration.
