Atomic models of two single joints connecting (a) (9, 0) to (5, 5) and (b) (10, 0) to (6, 6) nanotubes have been constructed and relaxed on the computer using a molecular-mechanics model. Each connection is based on a pair of diametrically opposed pentagon and heptagon which bend the structure. The electronic properties of these metal-metal and semiconductor-metal junctions are explored within a tight-binding description of the π bands of the carbon sp 2 network.
