"Symmetry properties of zinc-oxide nanorods and nanotubes"

Sreda, 30.3.2005. 13h (amfiteatar 661)

The point and space symmetries of ZnO nanorods and nanotubes are described 
by C6v point group and R70 (p63mc,L63mc) rod/line group. While C6v is the 
little group along Brillouin zone, the site-symmetry may be C3v, Cs, or C1. 
Hence, the direct optical transitions in these nanostructures obey the same 
selection rules as those at Γ point of bulk, whereas the rules for 
transitions involving bound states are different. Heterostructures and 
effects of magnetic or/and an electric field(s) on the symmetry properties 
of the nanostructures are considered.
