Wavelength, concentration, and distance dependence of nonradiative energy transfer to a plane of gold nanoparticles.
(2012)
Nonradiative energy transfer to metal nanoparticles is a technique used for optical-based distance measurements which is often implemented in sensing. Both Förster resonant energy transfer (FRET) and nanometal surface ...
Novel optical pulse characterization technique using sinusoidal optical phase modulation with a broad usable modulation amplitude range
(IEEE, 2009)
Advanced optical pulse characterization methods are essential for high-speed optical communications.
Recently non-iterative characterization of general optical pulses using sinusoidal optical phase modulation has
been ...
Blue amplified spontaneous emission from a stilbenoid-compound-doped polymer optical fiber
(2001)
We report on the fabrication and characteristics of a step-index glass-clad polymer optical fiber that uses a novel
fluorescent stilbenoid compound for lasing and amplification applications. The compound, 1,4-bis(4-diph ...
Dynamical tuning of energy transfer efficiency on a graphene monolayer
(2015)
In this contribution we present a theoretical investigation of the energy transfer efficiency between quantum systems placed in proximity of a monolayer of conducting graphene. We calculate the spontaneous emission rate ...
Realization of Zero-Field Skyrmions in a Magnetic Tunnel Junction
(2023)
Magnetic skyrmions are topologically protected noncollinear spin textures, which are regarded as promising information carriers for next-generation spintronic devices due to their small size and the low current density ...
Self-assembled broadband plasmonic nanoparticle arrays for sensing applications
(2012)
Highly ordered noble metal nanoparticle (NP) arrays are produced using a glancing angle deposition on stepped substrates. The versatility of the technique is demonstrated by depositing different metals, resulting in shifts ...
Reinforcement of macroscopic carbon nanotube structures by polymer intercalation: The role of polymer molecular weight and chain conformation
(American Physical Society, 2005)
Novel polymer nanotube composites were fabricated by intercalating poly(vinylpyrrolidone) into Buckypaper from solution. This was carried out for both low (10k g?mol) and very high (1.3M g?mol) molecular weight polymers. ...
Interfacial transport properties between a strongly correlated transition metal oxide and a metal: Contact resistance in Fe3O4/M (M=Cu, Au, Pt) nanostructures
(2010)
Multiterminal measurements have typically been employed to examine electronic properties of strongly correlated electronic materials such as transition metal oxides without the influence of contact effects. In contrast, ...
Quantifying the factors limiting rate-performance in battery electrodes
(2019)
One weakness of batteries is the rapid falloff in charge-storage capacity with increasing charge/discharge rate. Rate performance is related to the timescales associated with charge/ionic motion in both electrode and ...
Tunable linear magnetoresistance in MgO magnetic tunnel junction sensors using two pinned CoFeB electrodes
(2012)
MgO-barrier magnetic tunnel junction sensors with both CoFeB layers pinned by IrMn have been
fabricated, which show a tunneling magnetoresistance (TMR) of up to 255% at room temperature.
The perpendicular configuration ...
