Highly conductive nanolayers on strontium titanate produced by preferential ion-beam etching.

Developing fabrication methods for electronically active nanostructures is an important challenge of modern science and technology. Fabrication efforts for crystalline materials have been focused on state-of-the-art epitaxial growth techniques. These techniques are based on deposition of precisely controlled combinations of various materials on a heated substrate.

Capacitance-derived dielectric constants demonstrate differential preinitiation complexes in TBP-independent and TBP-dependent transcription.

The electronic properties of proteins and DNA may change dramatically upon complex formation, yet there are not many experimental methods which can be used to measure these properties. It has been previously shown that measuring the capacitance of a solution containing interacting DNA and protein species can yield information about changing dipole moments. The measured dielectric constant relates directly to the dipole moment of the complexes in solution.
