  2. [Illinois] AVS Meeting 2012: Adsorption and Desorption of Hydrogen on Epitaxial Graphene on SiC(0001): An Ultra-High Vacuum STM Study

    04 Jun 2013 | | Contributor(s):: TeYu Chien

    With superlative physical, chemical, and electronic properties, graphene shows significant promise in a variety of technologies, including transistors, sensors, and energy conversion/storage devices.However, as an atomically thin material, graphene is highly sensitive to its environment, which...

  3. [Illinois] AVS Meeting 2012: Dielectric Breakdown Study for High Performance, Reliable Top-gated Large-area Graphene Electronics

    04 Jun 2013 | | Contributor(s):: Vinod K. Sangwan

    An ultra-thin top-gate dielectric is essential for high-performance large-scale digital and analog electronics based on graphene field-effect transistors (G-FETs). Atomic layer deposition (ALD) has been utilized to grown top-gate dielectrics for high-performance G-FETs. However, ALD requires a...

  4. [Illinois] AVS Meeting 2012: Interfacial Processes in Li-ion Battery Anodes

    04 Jun 2013 | | Contributor(s):: Hadi Tavassol

    During Li+ transport, in Li-ion batteries, a solid electrolyte inter-phase (SEI) composed of breakdown products from the electrode, the solvent, and the electrolyte, forms on both cathode and anode electrode surfaces. Solvents, electrolytes, and electrode materials determine the thickness,...

  5. [Illinois] AVS Meeting 2012: Photoelectron and Electron Spectro-Microscopy in Liquids and Dense Gaseous Environment Using Electron Transparent Membranes

    04 Jun 2013 | | Contributor(s):: Andrei Kolmakov

    Novel bottom-up designed materials currently constitute the major source of innovations in electronics, optics, energy harvesting/storage, catalysis and bio-medical applications. The performance of these new materials and devices depends on physicochemical processes taking place at the interface...

  6. [Illinois] AVS Meeting 2012: Understanding Atomic-Layer-Deposition Synthesis of Cu 2 ZnSnS 4 Solar Cells

    04 Jun 2013 | | Contributor(s):: Sergey V. Baryshev

    Cu2ZnSnS4 (CZTS) has recently attracted attention as a light absorber for photovoltaic applications because of its band gap (εg≈1.4 eV), the relative abundance and low cost of its constituent elements (which permits large-scale low-cost module production), and its demonstrated...

  7. [Illinois] AVS Meeting 2012: Vacuum Insulation Panels with Tensile Supports to increase the Energy Efficiency of a Building's Envelope

    04 Jun 2013 | | Contributor(s):: Alan D. Feinerman

    Heating and cooling accounts for at least 36% of the energy consumed in the US and in nearly all cases increasing the insulation (R-value) of the thermal barrier will reduce the energy consumed. Space and economic considerations usually limit the insulation in the walls of a building's envelope...
