Band Gap Modulation in Single-Walled Carbon Nanotubes
MetadataShow full item record
Carbon nanotube (CNT) structures represent a recently discovered (1991) phase of carbon. The CNT structure is best described as a single graphene sheet rolled into a seamless tube. They can be classified into three categories depending on the geometry of the graphene sheet edge: zig-zag, armchair, and chiral. The different structures determine the electronic and mechanical properties of the CNT. Each CNT is uniquely identified by the index pair (n,m) that define the translation vector C on the graphene lattice. C maps an origin atom to its periodic partner at the opposite edge of the lattice.
