Angstrom-Scale Distance Dependence of Antenna-Enhanced Vibrational Signals

Angstrom-scale flatness using selective nanoscale etching

The realization of flat surfaces on the angstrom scale is required in advanced devices to avoid loss due to carrier (electron and/or photon) scattering. In this work, we have developed a new surface flattening method that involves near-field etching, where optical near-fields (ONFs) act to dissociate the molecules. ONFs selectively generated at the apex of protrusions on the surface selectively...

Nucleic acid nanotechnology-towards Angstrom-scale engineering.

Nucleic acids and analogues are suitable building blocks for reliable self-assembly of nanometer-sized two- or three-dimensional materials. In order to mimic or approach nature with respect to size and function, Angstrom-scale chemical engineering is emerging as pivotal for future developments. Efforts within nucleic acid nanotechnology will be focussed on generating rigid and stable low nanome...

A note on distance dependence in surface enhanced Raman spectroscopy

It is appreciated that the surface enhanced Raman signal falls away rapidly from the substrate surface that provides the dominant electromagnetic enhancement. As many bio-molecules of interest are large, it is important to establish for any practical surface the usable distance from the surface at which molecules can still be detected. Using monolayer ssDNA arrays with three adenine bases close...

Positive Dependence of Signals

In this paper we further investigate the problem considered by Mizuno (2006) in the special case of identically distributed signals. Specifically, we first propose an alternative sufficient condition of crossing type for the convex order to hold between the conditional expectations given signal. Then, we prove that the bivariate (2,1)-increasing convex order ensures that the conditional expecta...
