Zinc sulfide (ZnS) nanoparticles are of interest for their luminescent and catalytic properties which are useful in bio-medical, electronic and photovoltaic devices. However, ZnS nanoparticles undergo reversible and ...
We consider sums over the set of positive integers relevant to construction of periodic Green's functions for diffraction gratings and similar problems, and provide a general formula for a combination of Bessel functions ...

Environmental scanning electron microscopy (ESEM) enables electron imaging of gas-mediated, direct-write nanolithography processes, liquids, and hydrated biomaterials. However, ESEM is limited by poor image quality at gas ...
We prove a regularized formula for the secret key-assisted capacity region of a quantum channel for transmitting private classical information. This result parallels the work of Devetak on entanglement assisted quantum ...
We present a detailed theoretical study of the recent proposal for selective nanomanipulation of nanometric particles above a substrate using near-field optical forces [P.C. Chaumet et al., Phys. Rev. Lett. 88, 123601 ...

Semi-active H-infinity control of vehicle suspension with magneto-rheological (MR) damper is studied in this paper. First, an experiment is conducted on an MR damper prototype subjected to cyclic excitation. Then, a ...
We have developed semianalytical methods that allow us to perform a comprehensive analysis of the surface modes of photonic woodpiles. The surface modes of both finite and semi-infinite woodpiles are characterized using ...
We define the concept of an impedance matrix for three-dimensional (3D) photonic and metamaterial structures relative to a reference medium and show that it satisfies a matrix generalization of the basic algebraic properties ...
The radiative energy loss from an argon plasma in a shock tube has been investigated, with emphasis on the role of reabsorption. Electron densities reached values of 1.5*1024 electrons m-3 behind the primary shock, and ...
A rigorous quantitative verification technique is presented for nonlinear finite-difference time-domain (FDTD) algorithms by analyzing parametric four-wave mixing (FWM) in an optical Kerr medium without involving other ...

In this study, we report a simple and cost-effective method for in situ decoration of Ag NPs onto nanoporous TiO2 microrods by one medium (ethylene glycol) that can produce two different morphologies. In order to investigate ...
t has previously been established that the lowest energy site for chlorine atoms on Cu(111) is the fcc hollow. However, substantial population of the hcp hollow at room temperature indicates that there is a relatively ...

A spectroscopic ellipsometry compatible approach is reported for the optical study of Si quantum dots (QDs) in Si-rich nitride/silicon nitride (SRN/Si(3)N(4)) superlattice, which based on Tauc-Lorentz model and Bruggeman ...
We show that a waveguide with multiple gratings can have a modal dispersion relation which supports frozen light. This means that light can be coupled efficiently to low group velocity modes of an optical waveguide or can ...
We present a general, semimicroscopic, self-consistent treatment of spontaneous emission for a two-level atom in a dielectric microcavity with arbitrary shape. Both lossless and absorbing media are considered. Our approach ...
Bottom-up growth of microscopic pillars is observed at room temperature on GaN irradiated with a Ga+ beam in a gaseous XeF2 environment. Ion bombardment produces Ga droplets which evolve into pillars, each comprised of a ...

We demonstrate that due to the Rashba spin?orbit coupling in semiconductor quantum wells, there is strong photo-mixing by mobile carriers in the terahertz frequency regime. The third order nonlinear current is of the same ...
The growth of endohedral fullerene La@C82 films on Si(1 1 1) has been explored by scanning tunneling microscopy (STM). The STM images reveal the molecules are hexagonally close-packed in multilayer films with the inter-molecular ...
We discuss two examples of living creatures using photonic crystals to achieve iridescent colouration. The first is the sea mouse (Aphroditidae, Polychaeta), which has a hexagonal close packed structure of holes in its ...
