Who is Gerd Binnig?
Gerd Binnig is a renowned physicist, born in 1947 in Frankfurt, Germany. He is best known for his groundbreaking work in the field of microscopy, particularly for the invention of the
Scanning Tunneling Microscope (STM). Binnig's contributions have had a profound impact on the field of
Nanotechnology, providing scientists with a tool to visualize and manipulate individual atoms.
What is the Scanning Tunneling Microscope (STM)?
The Scanning Tunneling Microscope (STM), co-invented by Gerd Binnig and Heinrich Rohrer in 1981, revolutionized the way we observe surfaces at the atomic level. The STM operates by scanning a sharp metal tip very close to the surface of a conducting material. By measuring the
tunneling current that flows between the tip and the surface, the STM can produce images with atomic resolution. This invention earned Binnig and Rohrer the
Nobel Prize in Physics in 1986.
