Hydrophilic, cationic large-core star polymers and polymer networks: Synthesis and physicochemical characterization
(2008)Group transfer polymerization was used to prepare hydrophilic, cationic large-core star polymers (LCSPs) and networks of 2-(dimethylamino)ethyl methacrylate (DMAEMA) and ethylene glycol dimethacrylate (EGDMA) in a two-step ...

InAs quantum dots grown by molecular beam epitaxy on GaAs (211)B polar substrates
(2006)InAs nanostructures were grown by molecular beam epitaxy on GaAs (211)B at temperatures between 400-530 °C and growth rates that were varied between 0.1 to 0.02 mono-layers (ML) per second. For temperatures up to 500 °C ...

Study of optical fiber structures using atomic force microscopy and scanning near-field optical microscopy
(1996)Atomic force microscopy (AFM) and scanning near-field optical microscopy (SNOM) were used to study optical fiber structures. The refractive index profile of fiber was disclosed by surface topography of etched fiber endface ...

Superimposed gratings WDM on Ge-doped silica on silicon planar waveguide
(1996)Wavelength-division multiplexed (WDM) devices are becoming increasingly important for fiber-optics communication and sensing systems. Large-channel fanout, low loss, and compatibility with fiber connection, laser sources ...

Surface-related states in oxidized silicon nanocrystals enhance carrier relaxation and inhibit auger recombination
(2008)We have studied ultrafast carrier dynamics in oxidized silicon nanocrystals (NCs) and the role that surface-related states play in the various relaxation mechanisms over a broad range of photon excitation energy corresponding ...
