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.

Bis(ethylenedioxy)diselenadithiafulvalene (BEDO-STF)
Journal of Materials Chemistry, 1998As a new promising π-donor for organic metals and superconductors, the title compound has been synthesized without the use of highly toxic CSe2 or H2Se gas; the preparation of stable organic metals including a new κ-type salt is also mentioned.

The deposition of CTFs (and STFs) requires a directional vapor flux and a sufficiently low substrate temperature, so that the arriving adatoms move only short distances upon initial impingement with the growing film surface. More to the point, as discussed in Chapter 2, for vapor flux normal to the substrate CTFs have their origin in the atomic-level ...

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 ...

STFs: STAT-Containing Transcription Factors
1996The term signal transducing factor (STF) was coined recently257,259 to draw together an apparently diverse group of transcription factor complexes which are elicited following stimulation of cytokine receptors and PTK receptors.257 These STFs were originally revealed by dint of their ability to bind to specific DNA elements (known as STAT-binding ...

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 ...
