Scanning Tunneling Microscope

According to Gerd Binnig, it took two years for the scientific community to embrace the scanning tunneling microscope. Early images provided by the device were very small, providing little detail and data. Then, as output quality improved, researchers from other labs began working with the scope, and advancements steadily began to emerge. Resolution improved and imaging time decreased. Today’s nanoscale microscopes represent a dramatic advancement over the instruments available in the early days of nanotechnology research, up to just a decade ago.
