Crystallization of Ge in SiO2 matrix by femtosecond laser processing
(American Vacuum Society, 2012-01-19)Germanium nanocrystals embedded in a siliconoxide matrix has been fabricated by single femtosecond laser pulse irradiation of germanium doped SiO2 thin films deposited with plasma enhanced chemical vapor deposition. SEM ... -
Field-effect-assisted photoconductivity in PbS films deposited on silicon dioxide
(American Institute of Physics, 2002-05-01)Lead sulfide (PbS) thin films were deposited from a chemical bath onto SiO2/Si (n-type) substrates. Pseudo-metal-oxide-semiconductor devices were obtained by evaporating source and drain gold electrodes on a PbS surface ... -
Free-standing ZnO-CuO composite nanowire array films and their gas sensing properties
(IOP Publishing, 2011-07-19)A modified hydrothermal method was developed to synthesize ZnO-CuO composite nanostructures. A free-standing film made of ZnO-CuO nanostructures was assembled on the surface of the hydrothermal solution with a smooth surface ... -
Low-loss as-grown germanosilicate layers for optical waveguides
(A I P Publishing LLC, 2003)We report on systematic growth and characterization of low-loss germanosilicate layers for use in optical waveguide technology. The films were deposited by plasma-enhanced chemical vapor deposition technique using silane, ... -
Low-Temperature Deposition of Hexagonal Boron Nitride via Sequential Injection of Triethylboron and N2/H2 Plasma
(Wiley-Blackwell Publishing, Inc., 2014)Hexagonal boron nitride (hBN) thin films were deposited on silicon and quartz substrates using sequential exposures of triethylboron and N 2 /H 2 plasma in a hollow-cathode plasma- assisted atomic layer deposition ... -
Mechanical, electronic, and optical properties of Bi2S3 and Bi2Se3 compounds: first principle investigations
(Springer Berlin Heidelberg, 2014)The structural, mechanical, electronic, and optical properties of orthorhombic Bi2S3 and Bi2Se3 compounds have been investigated by means of first principles calculations. The calculated lattice parameters and internal ... -
Resonant nonradiative energy transfer in CdSe/ZnS core/shell nanocrystal solids enhances hybrid white light emitting diodes
(Optical Society of America, 2008)We propose and demonstrate hybrid white light emitting diodes enhanced with resonant nonradiative energy transfer in CdSe/ZnS core/shell nanocrystal solids integrated on near-UV InGaN/GaN LEDs. We observe a relative quantum ...
