An atomic force microscope can be used as a single-electron current meter, according to new experiments by researchers at IBM. The technique, which measures the energy levels of single molecules on ...

Scientists have discovered a way to efficiently transfer electrical current through specific materials at room temperature, a ...

CRUISING AT about half the speed of light, tightly focused beams of electrons pass through thin slices of materials and carry away subtle information about the substance's structure and composition.

Taking advantage of quantum mechanical effects can be an alternative method for modifying current in high-sensitivity ...

There could soon be a new and more accurate method of defining the standard unit of current, the ampere, thanks to a tiny electronic device built by physicists in Finland and the US. The team, led by ...
