Abstract : This report describes the acquisition, set-up and use of essential equipment for studying surface nanoscale electronics and the progress in the related research projects where such equipment has been or will be used. During the past year, using this DURIP award, we installed a larger UHV chamber, implemented an auxiliary ultraviolet photoemission system (UPS), and established an electron-beam writing system. We have studied several nanostructured surface systems in stepped single-crystal surfaces and observed electron lateral 1D confinement and coherent effects using high-resolution angle-resolved two-photon photoemission. We investigated height-dependent (in nanoscale) electronic structures using sp-like surface state and image state electrons and observed distinct differences in the electron kinetics. We have been able to successfully generate patterns of dots and line structures of approximately 100nm in a variety of metal and semiconductor substrates.
