Sentences with phrase «by scanning probe microscope»

Not exact matches

Data is read by scanning gaps between atoms and the microscope's probe.

Those probes can image a surface at the atomic level by detecting the tunneling of electrons from the surface across a small gap to the microscope's tiny scanning tip.

Eigler's breakthrough was made possible thanks to the invention of the scanning tunneling microscope (STM) by Gerd Binning and Heinrich Rohrer in 1981, a device that made possible the imaging of atoms by measuring changes in the way electrons hop between a sharp probe and a specimen, as the probe shifts position.

His research over the last 25 years has focused on the development and application of new scanning probe microscopes, including the invention of two new types of high - speed AFM and the use of nanotools controlled by holographic optical tweezers to act as a new type of AFM probe.
