Park JH, Cho DH, Moon Y, Shin HC, Ahn SJ, Kwak SK, Shin HJ, Lee C, Ahn JR.
PMID: 25329767
ACS Nano. 2014 Nov 25;8(11):11657-65. doi: 10.1021/nn504956h. Epub 2014 Oct 29.

Single-crystal carbon nanomaterials have led to great advances in nanotechnology. The first single-crystal carbon nanomaterial, fullerene, was fabricated in a zero-dimensional form. One-dimensional carbon nanotubes and two-dimensional graphene have since followed and continue to provide further impetus to this...
