In operandi observation of dynamic annealing: A case study of boron in germanium nanowire devices
(2015)
We report on the implantation of boron in individual, electrically contacted germanium nanowires with varying diameter and present a technique that monitors the electrical properties of a single device during implantation ...
Calculation of gain?current characteristics in ZnCdSe?ZnSe quantum well structures including many body effects.
(American Institute of Physics, 1996)
The gain-spontaneous recombination characteristics have been calculated for a 40 ? Zn0.8Cd0.2Se-ZnSe quantum well including many body effects. We examine the effect of the inclusion of the Coulomb enhancement on the gain ...
Formation of the strain-induced electronic superstructure on the magnetite (111) surface
(2003)
We present direct experimental evidence of the formation of a superstructure on
the (111) surface of a magnetite, Fe3O4 single crystal. The superstructure, which has a periodicity
of 42A and three-fold symmetry, has been ...
Modification of photon states in photonic molecules with semiconductor nanocrystals
(Springer, 2005)
We report on the coherent coupling of whispering gallery modes (WGM) in a photonic molecule formed from two melamine-formaldehyde spherical microcavities coated with a thin shell of CdTe nanocrystals (NCs). Utilizing ...
Controlled in situ growth of tunable plasmonic self-assembled nanoparticle arrays
(2012)
Self-assembled silver nanoparticle (NP) arrays were produced by deposition at glancing angles on transparent stepped Al2O3 templates. The evolution of the plasmonic resonances has been monitored using reflection anisotropy ...
The Crystal Structure of Bubbles in the Wet Foam Limit
(2006)
We have observed a rich variety of three-dimensional crystal and defect structures spontaneously formed by small (diameter 200 µm) bubbles in a wet foam. The observations confirm and extend those made by Bragg and Nye in ...
Implementation of Morse-Witten theory for a polydisperse wet 2D foam simulation
(Taylor & Francis, 2019-06)
The Morse–Witten theory provides a formulation for the inter-bubble forces and corresponding deformations in a liquid foam, accurate in the limit of high liquid fraction. Here we show how the theory may be applied in ...
Optimizing transport in a homogeneous network
(American Physical Society, 2004)
Many situations in physics, biology, and engineering consist of the transport of some physical quantity
through a network of narrow channels. The ability of a network to transport such a quantity in every direction
can ...
A study of spin polarization in potential half-metals
(Trinity College (Dublin, Ireland). School of Physics, 2006)
The study presented in this thesis has been concerned with measuring spin polarisation
in magnetic materials using two methods: i) measurement of magnetoresistance in room
temperature point contacts and ii) Point Contact ...
Critical behavior of La0.75Sr0.25MnO3
(American Physical Society, 2002)
Magnetization, susceptibility, and specific heat measurements were made on a single crystal of La0.75Sr0.25MnO3. The ferromagnetic-to-paramagnetic phase transition was found at 346 K and four critical exponents were measured ...
