The key role of antibonding electron transfer in surface chemisorption and heterogeneous catalysis
Liping Yu, Qimin Yan, Adrienn Ruzsinszky
The description of the chemical bond between a solid surface and an atom or a molecule is the fundamental basis for understanding a broad range of scientific problems in heterogene…
Near-Field Thermal Emission by Periodic Arrays
Sheila Edalatpour
Near-field thermal emission can be engineered by using periodic arrays of sub-wavelength emitters. The array thermal emission is dependent on the shape, size, and materials propert…
The Measurement of Near-Field Thermal Emission Spectra using an Infrared Waveguide
Saman Zare, Carl Tripp, Sheila Edalatpour
We describe a simple and robust method using an internal reflection element acting as an infrared waveguide to measure the spectra of near-field thermal emission. We experimentally…
Spectral redshift of the thermal near field scattered by a probe
Sheila Edalatpour, Vahid Hatamipour, Mathieu Francoeur
The physics underlying spectral redshift of thermally generated surface phonon-polaritons (SPhPs) observed in near-field thermal spectroscopy is investigated. Numerically exact flu…
A finite analogue of the ring of algebraic numbers
Julian Rosen
We construct an analogue of the ring of algebraic numbers, living in a quotient of the product of all finite fields of prime order. We use this ring to deduce some results about li…
Nature of the positron state in CdSe quantum dots
Wenqin Shi, Vincent Callewaert, Bernardo Barbiellini +11
Previous studies have shown that positron-annihilation spectroscopy is a highly sensitive probe of the electronic structure and surface composition of ligand-capped semiconductor Q…
