Scanning Tunneling Microscopes

News Scanning Tunneling Microscopes

  • Sensing magnetism in atomic resolution with just a scanning tunneling microscope

    Scientists from the University of Strasbourg, France, in close collaboration with colleagues from the research centers in San Sebastián, Spain, and Jülich, Germany, have achieved a breakthrough in detecting the magnetic moments of nanoscale structures. They succeeded in making the magnetic moments v more

  • Single molecule control for a millionth of a billionth of a second

    Physicists at the University of Bath have discovered how to manipulate and control individual molecules for a millionth of a billionth of a second, after being intrigued by some seemingly odd results. Their new technique is the most sensitive way of controlling a chemical reaction on some of the sma more

  • UO-industry collaboration points to improved nanomaterials

    A potential path to identify imperfections and improve the quality of nanomaterials for use in next-generation solar cells has emerged from a collaboration of University of Oregon and industry researchers. To increase light-harvesting efficiency of solar cells beyond silicon's limit of about 29 perc more

  • Time-Dependent Density Functional Theory for Open Systems and Its Applications

    ConspectusPhotovoltaic devices, electrochemical cells, catalysis processes, light emitting diodes, scanning tunneling microscopes, molecular electronics, and related devices have one thing in common: open quantum systems where energy and matter are not conserved. Traditionally quantum chemistry is c more

  • Atom-by-Atom Construction of a Quantum Device

    Scanning tunneling microscopes (STMs) are conventionally used to probe surfaces with atomic resolution. Recent advances in STM include tunneling from spin-polarized and superconducting tips, time-domain spectroscopy, and the fabrication of atomically precise Si nanoelectronics. In this issue of ACS more

  • Fixed-Gap Tunnel Junction for Reading DNA Nucleotides

    Previous measurements of the electronic conductance of DNA nucleotides or amino acids have used tunnel junctions in which the gap is mechanically adjusted, such as scanning tunneling microscopes or mechanically controllable break junctions. Fixed-junction devices have, at best, detected the passage more
