Monolithic Integration of Gaas/Ingaas Laserson Virtual Ge Substrates Via Aspect-Ratio Trapping
GaAs/InGaAs quantum-well lasers have been demonstrated by metallorganic chemical vapor deposition on virtual Ge substrates on Si via aspect-ratio trapping (ART) and epitaxial lateral overgrowth (ELO).

Public-Key Cryptosystems from the Worst-Case Shortest Vector Problem
We construct public-key cryptosystems that are secure assuming theworst-case hardness of approximating the minimum distance on n-dimensional lattices to within small Poly(n) factors.

Form GaAs/IngaAs Lasers on Virtual Ge
This article reports on 980-nm GaAs/In- GaAs lasers grown on virtual Ge substrates, for which the Ge thin film was grown on Si (001) substrates via the ART method followed…

Hydrogen Collisions in Planetary Atmospheres, Ionospheres, and Magnetospheres
Here we present a critical evaluation of the current state of understanding of the chemical reaction rates and collision cross sections for several important hydrogen collision processes in planetary atmospheres, ionospheres,…

Characterization of flexible image sensor arrays with bulk heterojunction organic photodiodes
Abstract A prototype of mechanically flexible photosensor arrays using organic bulk heterojunction photodiodes has been developed on plastic substrates. The integration of a 4 m thick sensor layer onto a…

Spatially Correlated Fluctuations and Coherence Dynamics in Photosynthesis
Here we present a generic model in which a strong intermolecular steric restoring force in densely packed pigment-protein complexes results in a spatial correlation in conformational (static) variations of chromophores,…

Near-Infrared Fluorescent Labeling of Tissue Transglutaminase Substrates for Imaging Tumor Boundaries
A novel strategy is developed to optically image tumor boundaries by cross-linking near-infrared fluorescent-labeled tissue transglutaminase substrates into tumor boundary tissue.

High-Index-Contrast AlGaAs Waveguide Scattering Loss Reduction Via Oxidation Smoothing of Sidewall Roughness
The propagation loss of single mode high index contrast AlGaAs ridge waveguides is reduced nearly three orders of magnitude through application of a nonselective wet oxidation sidewall roughness smoothing technique.

Microscopic Theory of Electron Spin Relaxation in N@ C60
Here, we present a microscopic theory of electron spin relaxation in N@C60. The theory combines (1) the spin-orbit interaction of N 2p electrons, which mixes the ground-state 4S with excited 2P and 2D states.
