Optical Spectroscopy of Single Impurity Molecules in Solids
Abstract Optical spectroscopy of a single impurity molecule provides the first truly local probe of host–guest interactions in doped solids. In conventional optical high‐resolut...
Optical constants of conjugated polymer/fullerene based bulk-heterojunction organic solar cells
The performance of organic solar cells consisting of multiple layers, which are a few hundred nanometers thick, is determined by strong optical interference effects. In order to...
Routing in Communications Networks
I. CIRCUIT-SWITCHING NETWORKS. AT&Ts Dynamic Routing Network, G.R. Ash Dynamic Alternative Routing, R.J. Gibbens, F.P. Kelly, and P.B. Key II. PACKET-SWITCHING NETWORKS. Distanc...
Molecular Scale Buckling Mechanics in Individual Aligned Single-Wall Carbon Nanotubes on Elastomeric Substrates
We have studied the scaling of controlled nonlinear buckling processes in materials with dimensions in the molecular range (i.e., approximately 1 nm) through experimental and th...
Sharply directed emission in organic electroluminescent diodes with an optical-microcavity structure
An optical microcavity structure was introduced into organic three-layer electroluminescent (EL) diodes with a europium complex as an emission layer. The device structure consis...
3D Metallo-Dielectric Photonic Crystals with Strong Capacitive Coupling between Metallic Islands
We introduce a new type of metallo-dielectric photonic band gap structure (PBG), intentionally incorporating very strong capacitive interactions between the periodic metallic is...
Optical properties of large-area polycrystalline chemical vapor deposited graphene by spectroscopic ellipsometry
Spectroscopic ellipsometry was used to characterize the complex refractive index of chemical vapor deposition (CVD) graphene grown on copper foils and transferred to glass subst...
Characterization of silicon avalanche photodiodes for photon correlation measurements 1: Passive quenching
We examine the photon correlation and other vital performance characteristics of silicon avalanche photodiodes operated in photon counting or the Geiger mode, and assess their s...
BOOSTING PERFORMANCE IN NEURAL NETWORKS
A boosting algorithm, based on the probably approximately correct (PAC) learning model is used to construct an ensemble of neural networks that significantly improves performanc...
