a scanning tunneling microscope measures electrons that leak, or 'tunnel', fromthe surface of specimen
Scanning tunneling microscopes (STM) are primarily used in nanotechnology and materials science to visualize surfaces at the atomic level. They enable the study of electronic properties of materials, allowing researchers to investigate phenomena like superconductivity and quantum effects. Additionally, STMs are valuable in the fabrication of nanoscale devices and the manipulation of individual atoms for creating new materials. Their ability to provide high-resolution images makes them essential in fields such as surface chemistry and semiconductor research.

The best images from an electron microscope are typically obtained at magnifications ranging from 10,000x to 1,000,000x. This range allows for detailed visualization of cellular structures, organelles, and macromolecules. However, the optimal magnification can depend on the specific specimen and the type of electron microscope used, whether it’s a transmission or scanning electron microscope. Higher magnifications can sometimes lead to a loss of image clarity, so a balance is essential.
Nanotechnology was conceptualized in 1959 when physicist Richard Feynman delivered his famous lecture "There's Plenty of Room at the Bottom," envisioning the manipulation of individual atoms and molecules. The field gained momentum in the 1980s with advancements in microscopy techniques, such as scanning tunneling microscopy, which allowed scientists to visualize and manipulate nanoscale materials. Since then, interdisciplinary research has led to the development of various applications across fields like medicine, electronics, and materials science, transforming nanotechnology into a pivotal area of modern science and engineering.
The transmission electron microscope (TEM) was invented in the 1930s, with significant advancements made by physicists Ernst Ruska and Max Knoll. They developed the first functional TEM in 1931, which allowed for the visualization of ultra-thin samples at much higher resolutions than light microscopes. This groundbreaking invention has since revolutionized materials science, biology, and nanotechnology.
The scanning tunneling microscope and the first 3d video game.
The first scanning tunneling microscope was invented in 1982 by Binnig and Rohrer. They won the Nobel Prize in Physics in 1986 for their invention.

With a Scanning tunneling microscope STM
The Scanning Tunneling Microscope was invented by two men by the names of Gerd Binnig and Heinrich Rohrer in 1981. While they did research on the product they used the tools and facilities of Penn State. As the product became ready one of the investors was IBM.

In 1981 the Scanning Tunneling Microscope (STM) was invented. The STM has ultrahigh resolution and can image single atoms.
Scanning tunneling electron microscope
The needle in a scanning tunneling microscope is typically on the nanometer scale, ranging from 1 to 10 nanometers in diameter. Its sharp tip allows for atomic-scale resolution during imaging by detecting the tunneling current between the tip and the surface being scanned.

to see images of surface at the atomic level!
The scanning tunneling microscope allows scientists to see individual atoms on a surface by detecting the tunneling current between the microscope tip and the sample. The one-angstrom microscope is a hypothetical concept that would potentially allow scientists to visualize atomic details with even higher resolution.
