What does STM mean in ACADEMIC & SCIENCE
A Scanning Tunneling Microscope (STM) is a type of microscope used to study the physical properties of surfaces or samples at a very small scale. It uses a scanning tunneling current and electromagnetic force to create high resolution images of the sample surface. The technique was first developed in the late 1980s and has since been used for a variety of scientific research applications.

Essential Questions and Answers on Scanning tunneling microscope in "SCIENCE»SCIENCE"
What is an STM?
An STM is a Scanning Tunneling Microscope, which utilizes scanning tunneling current and electromagnetic force to create high resolution images of the surface of a sample.
What kind of research applications can an STM be used for?
STMs have been used in many different types of scientific research, including nanotechnology, materials science, organic chemistry, and more.
How does an STM work?
An STM works by using an electric current that flows between two electrodes (the tip and the sample) to measure the height differences on the surface of the sample. This creates a high-resolution image of the surface.
When was the STM developed?
The first prototype Scanning Tunneling Microscope was developed in 1981 by Gerd Binnig and Heinrich Rohrer at IBM Zurich Research Laboratory in Switzerland.
What is needed for an STM to operate?
For an STM to operate, it needs a vacuum chamber with pressure below 10^-6 torr (1 trillionth atmosphere), ultra-high purity ultra-smooth substrates coated with gold or other metals, low noise amplifiers, lasers and digital electronics for imaging control, feedback control algorithms for controlling distance between tip and substrate as well as alignment issues with respect to scan area.
Final Words:
The Scanning Tunneling Microscope (STM) is an important tool that has revolutionized our ability to study surfaces at a subatomic scale. By applying electric currents between two electrodes—the tip and sample—and measuring height differences on the surface, researchers can gain detailed information about how materials interact on such small scales. This powerful tool has made possible new discoveries across numerous fields such as nanotechnology, materials science, organic chemistry and more since its development in 1981.
