Atomic Resolution Breakthrough in Scanning Tunneling Microscopy

13 11 2010

Under a scanning tunneling microscope (STM), molecules usually appear as indistinct blobs. But research published in the 20 August Physical Review Lettersshows how a recently developed type of STM can reveal the structure of a molecule in much greater detail. In this type of STM, a single hydrogen or deuterium molecule is attached to the probe tip, and the team showed that the pressure of this molecule against the probe leads to the dramatic improvement in imaging.
