Heineich Rohrer & Gerd Binnig
The other half of the Nobel Prize went to: Heinrich Rohrer and Gerd Binnig for earlier inventing the scan tunneling microscope in 1981. This microscope gives 3-D or three dimensional images down to the atomic level. The scan tunneling microscope is used in industrial and fundamental research. The scan tunneling microscope also shows the viewer images of metal surfaces, it characterizes the surface roughness and defects, and it determines the sizes of molecules and aggregates on the surface of atoms or metals.
