Microscopic analysis of gain spectrum of surface plasmons in graphene
Results in Physics, 2016 In this paper, microscopic interactions of surface plasmons and carriers in the graphene layer are investigated and based on the second quantization formalism, rate equations of surface plasmons are presented. Plasmonic matrix element for surface plasmon-

A phased antenna array for surface plasmons. [PDF]
Sci Rep, 2016 Surface plasmon polaritons are electromagnetic waves that propagate tightly bound to metal surfaces. The concentration of the electromagnetic field at the surface as well as the short wavelength of surface plasmons enable sensitive detection methods and ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Graphene plasmons in the presence of adatoms
New Journal of Physics, 2017 We theoretically investigate graphene plasmons in the presence of a low density of adatoms on the graphene surface. The adatoms can significantly modify the conductivity and plasmonic properties of graphene and may produce a level splitting with the ...

Tunable grating-assisted surface plasmon resonance by use of nano-polymer dispersed liquid crystal electro-optical material [PDF]
, 2007 This paper reports on the experimental observation of the displacement of a surface plasmon resonance (SPR) excited by a metallic diffraction grating. This effect is achieved by the use of an electro-optical material composed of nano-sized droplets of ...

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein
FEBS Letters, EarlyView.Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Optical Surface Plasmons in Semiconductors
, 2012 ThesisA theoretical treatment is presented of a plasmonic interaction at an interface between a semiconductor and a dielectric, as opposed to the more traditional configuration whereby a metal/dielectric interface is investigated.

Focusing short-wavelength surface plasmons by a plasmonic mirror [PDF]
Optics Letters, 2018 Emerging applications in nanotechnology, such as superresolution imaging, ultra-sensitive biomedical detection, and heat-assisted magnetic recording, require plasmonic devices that can generate intense optical spots beyond the diffraction limit. One of the important drawbacks of surface plasmon focusing structures is their complex design, which is ...
