Measuring electrical conductance across a single molecule

When noble metals, like gold, are treated with an aliphatic thiol, like alkanethiol, a uniform monolayer—a layer only one molecule deep—self-assembles on the surface. Each individual molecule can conduct electrons. This ...

Building bridges between nanowires

Place a layer of gold only a few atoms high on a surface bed of germanium, apply heat to it, and wires will form of themselves. Gold-induced wires is what Mocking prefers to call them. Not 'gold wires', as the wires are not ...

Visualizing short-range charge transfer at interfaces

The precise mechanisms governing the relationships between superconductivity and magnetism were examined by using advanced scanning tunneling microscopy (STM) at the Center for Nanoscale Materials by users from Argonne's ...

Analyzing the status of oxide surface photochemical reactivity

As shown by Pacific Northwest National Laboratory's Dr. Michael Henderson and Dr. Igor Lyubinetsky in their invited review article, using scanning probe microscopy techniques, in particular scanning tunneling microscopy or ...
