STM runs faster
Ordinary scanning tunnelling microscopes (STMs) could soon be collecting images 100-times faster than ever before thanks to a simple but clever modification by physicists in the US. The team added a specially-designed radio-frequency circuit to an existing STM, which allows it to operate at 10 MHz. Such RF-STMs could help researchers gain a better understanding of how atoms and electrons move in solids.
