Title: Giant Metal Compression at Liquid-Solid (Pb-Si, In-Si) Schottky Junctions

Abstract

Using a high-energy x-ray transmission-reflection scheme we have studied the density profile of solid-liquid Schottky contacts close to the interface. We found a massive disturbance of the electronic system on the liquid metal side at different interfaces with pronounced density anomalies on a new length scale. The liquid metal at the interface forms a strongly compressed layer followed by a density depleted layer. The experimental evidence points to a charge transfer phenomenon in the metallic system. Control experiments performed at a metal-insulator interface confirm this picture.

  • We have utilized high-resolution synchrotron-radiation photoemission spectroscopy and high-energy electron diffraction to study the various reconstructed surfaces of Pb-covered Si(111). The Si 2{ital p} and Pb 5{ital d} core levels and valence bands are analyzed as a function of Pb coverage and annealing temperature. We confirm the room-temperature (RT) Stranski-Krastanov growth mode with the two-dimensional adlayer completed at {similar to}1.3 monolayers. The formation of the Schottky barrier has been studied. We measure {ital n}-type barrier heights of 0.89 and 1.09 eV for the RT epitaxial phase and the ({radical}3 {times} {radical}3 ){ital R}30{degree} incommensurate phase, respectively. Possible mechanisms that maymore » be responsible for the disagreement between barrier heights as measured by core-level photoemission and electrical techniques are discussed. We also report on the observation of surface-shifted core levels and surface states in the valence band for the ({radical}3 {times} {radical}3 ){ital R}30{degree} phases obtained by annealing to higher temperatures in the desorption regime. These results are used for an investigation of the structural models for these surface phases.« less

  • The modulation of Schottky barrier height of metal/Ge inserting an amorphous Ge layer has been demonstrated. It is interested that the Schottky barrier height of Al/amorphous-Ge/n-Ge junctions is oscillated with increase of the a-Ge thickness from 0 to 10 nm, and when the thickness reaches above 10 nm, the Al/amorphous-Ge/n-Ge shows ohmic characteristics. Electron hopping through localized states of a-Ge layer, the alleviation of metal induced gap states, as well as the termination of dangling bonds at the amorphous-Ge/n-Ge interface are proposed to explain the anomalous modulation of Schottky barrier height.
  • A description is given of the properties and fabrication of a superconductor-semiconductor-superconductor Josephson device based on a novel step-edge technique. This technique allows for careful control of device lengths down to 100 nm. The fabricated devices exhibit high normal-state resistances and surprisingly strong Josephson coupling. The temperature dependence of the measured critical currents suggests that the coherence length in silicon is higher than predicted. The results suggests that silicon barrier devices can perform as well as devices made with other semiconductors with higher mobilities.
  • Transconductance measurements using Si electrodes were conducted to distiguish faradaic and solid-state conduction pathways using ac impedance measurements. These measurements show that contact with 1,1{prime}-dimethylferrocene and ferrocene redox couples in CH{sub 3}OH(l)-1.0 M LiClO{sub 4} formed an inversion layer in the n-Si, but the solution with Me{sub 10}Fc did not. The barrier heights of these junctions were also obtained. 40 refs., 14 figs.
