  We investigate the electronic properties of sculpturenes, formed by sculpting
selected shapes from bilayer graphene, boron-nitride or graphene-boron-nitride
hetero-bilayers and allowing the shapes to spontaneously reconstruct. The
simplest sculpturenes are periodic nanotubes, containing lines of non-hexagonal
rings. More complex sculpturenes formed from shapes with non-trivial
topologies, connectivities and materials combinations may also be constructed.
Results are presented for the reconstructed geometries, electronic densities of
states and current-voltage relations of these new structures.
