Abstract

Several new metallic and semiconducting nanostructures may provide interesting substrates for observations involving quantum coherence. Boron-based nanotubes with beryllium atoms in the hexagonal faces should exhibit uniformly metallic properties with multiple conduction channels of disparate character. The apical dislocation in a carbon nanocone mixes the low-energy electronic states of a graphene sheet and produces a geometrically derived effective flux through the apex which suppresses the Aharonov-Bohm effect.
