Abstract
In this paper we demonstrate, using density-functional tight-binding theory , that certain classes of germanium-based tubular nanostructures are stable and energetically viable. Specifically, we consider GeH nanotubes. The str uctures adopted by these nanotubes are very similar to those of previously reported silane and siloxene nanotubes. The Ge-based nanotubes have a semic onducting gap which is dependent on the tube diameter. (C) 2001 Elsevier Sc ience Ltd. All rights reserved.
