Three-dimensional sculpturing of columnar morphology is most easily achieved by rotating the substrate about an axis normal to the substrate plane, during physical vapor deposition. The vapor flux density and the substrate rotation velocity have to be maintained at fixed values.

Speculations on STF Morphology
2009Virtually all STFs fabricated to date have been grown on flat substrates, with few exceptions [148, 154, 303]. Deposition is random in the xy plane, but not along the z axis. Since clusters of 1- to 3-nm size are the fundamental building blocks of the matchstick morphology, morphological changes along the z axis can be induced with transitions not ...

Optical Applications of Chiral STFs
2009The chief optical characteristic of chiral STFs is their display of the circular Bragg phenomenon. As discussed in Sec. 9.3.4, this phenomenon is the distinction between the responses to normally incident plane waves of orthogonal circular polarization states in a certain wavelength regime; i.e., the creation of a circular-polarization-sensitive ...

The interrelationship between graph theory and differential geometry has played an important role in these two areas of research over the last ten years. Applications of this work have appeared in communication networks, the work on expanders, superconcentrators and Ramanujan graphs (v., Lubotzky (1994)) and in work on coding theory (v., e.g.
