    17 May 2007 | | Contributor(s):: Dmitry Zemlyanov

    X-ray Photoelectron Spectroscopy (XPS), which is known as Electron Spectroscopy for Chemical Analysis (ESCA), is a powerful research tool for the study of the surface of solids. The technique is widely used for studies of the properties of atoms, molecules, solids, and surfaces. The main success...

  7. Electron Emission from Nanoscale Carbon Materials

    15 May 2007 | | Contributor(s):: Timothy S Fisher

    Prior studies on electron emission show possibly beneficial effects ofnanoscale phenomena on energy-conversion characteristics. For example,recent work has shown that the electric field around a nanoscale fieldemission device can increase the average energy of emitted electrons. Weconsider here...

  8. Technology challenges of the 21st Century

    14 May 2007 | | Contributor(s):: Eugene Meieran

    The 20th century was a century of remarkable scientific and technical achievement, as recorded in the National Academy of Engineering book, "A Century of Innovation". Three forces ("a perfect storm") combined to make this possible; almost universal availability of electric power to enable many...

  9. Modeling and Analysis of VLSI Interconnects

    10 May 2007 | | Contributor(s):: Cheng-Kok Koh

    With continual technology scaling, the accurate and efficient modeling and simulation of interconnect effects have become problems of central importance. In order to accurately model the distributive effects of interconnects, it is necessary to divide a long wire into several segments, with each...
