    Completely random nanoporous Cu4O3–CuO–C composite thin films for potential application as multiple channel photonic band gap based filter in the telecommunication wavelengths

    In 2003, Babin et al. theoretically predicted (J. Appl. Phys. 94:4244, 2003) that fabrication of organic–inorganic hybrid materials would probably be required to implement structures with multiple photonic band g...

    Organic Functionalization of Solution-Phase Exfoliated Graphene

    Graphene has received increasing attention due to its unique physicochemical properties. The ability to control the size and dispersion of graphene sheets in a variety of organic solvents and water is probably...

    Assembly of sol–gel-grown Li x CoO2 nanocrystals through electromagnetic irradiation

    We report the fabrication of assembled nanostructures from the pre-synthesized nanocrystals building blocks through optical means of exciton formation and dissociation. We demonstrate that Li x ...

    HRTEM and STXM, a combined study of an individual focused-ion-beam patterned CNT

    Carbon nanotubes (CNTs) are either metallic or semiconducting and are unique in terms of their chemical and thermal stability, strength and elasticity. The combination of all these properties is expected to re...

    Nucleation of Metal Clusters on Carbon Nanotubes

    Electromigration in metal interconnects limits the number of devices in a single microprocessor. This limitation has already led to the replacement of Al as interconnect material by Cu, which has a higher curr...

    STXM-NEXAFS of individual titanate-based nanoribbon

    In recent years, many low dimensional TiO2-materials, such as nanowires, nanotubes, and nanorods have been successively synthesized. These novel nanostructures bring to reality the possibility to fine tune che...

    Photoelectric-Yield Studies of c-Si/a-Si:H Interfaces

    We report the first yield spectroscopy study on well characterized c-Si/a-Si:H heterojunctions grown in situ under UHV conditions. We find that this spectroscopy, when operated in the constant final state mode, a...
