  • Autonomous Robot Plays with NanoLEGO

    Molecules are the building blocks of everyday life. Many materials are composed of them, a little like a LEGO model consists of a multitude of different bricks. But while individual LEGO bricks can be simply shifted or removed, this is not so easy in the nanoworld. Atoms and molecules behave in a co more

  • An ultrafast microscope for the quantum world

    Processes taking place inside tiny electronic components or in molecules can now be filmed at a resolution of a few hundred attoseconds and down to the individual atom. The operation of components for future computers can now be filmed in HD quality, so to speak. Manish Garg and Klaus Kern, research more

  • 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

  • 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
