A scanning tunneling microscope (STM) is a type of scanning probe microscope used for imaging surfaces at the atomic level. Its development in 1981 earned its inventors, Gerd Binnig and Heinrich Rohrer , then at IBM Zürich , the Nobel Prize in Physics in 1986.
Mechanism of how density of states influence V-A spectra of tunnel junction. Scanning tunneling spectroscopy is an experimental technique which uses a scanning tunneling microscope (STM) to probe the local density of electronic states (LDOS) and the band gap of surfaces and materials on surfaces at the atomic scale.

In standard scanning tunneling microscopy (STM), the tunneling probability of electrons between the probe tip and the sample strongly depends on the distance between them, as it decays exponentially as the separation increases. In spin-polarized STM (SP-STM) the tunneling current also depends on the spin-orientation of the tip and the sample.
The scanning tunneling microscope (STM) uses the concept of quantum tunneling to directly image atoms. A STM can be used to study the three-dimensional structure of a sample, by scanning the surface with a sharp, metal, conductive tip close to the sample.
Multi-tip scanning tunneling microscopy (Multi-tip STM) extends scanning tunneling microscopy (STM) from imaging to dedicated electrical measurements at the nanoscale like a ″multimeter at the nanoscale″. In materials science, nanoscience, and nanotechnology, it is desirable to measure electrical properties at a particular position of the ...
The electrochemical scanning tunneling microscope (EC-STM) is a scanning tunneling microscope that measures the structures of surfaces and electrochemical reactions in solid-liquid interfaces at atomic or molecular scales.
Atomic manipulation is the process of moving single atoms on a substrate using Scanning Tunneling Microscope (STM). The atomic manipulation is a surface science technique usually used to create artificial objects on the substrate made out of atoms and to study electronic behaviour of matter. These objects do not occur in nature and therefore ...
Nanosurf invented the first scanning tunneling microscope (STM) with the compact size and stability to image individual atoms on a coffee table.In its early days, Nanosurf became known for educational AFMs, and over the course of the following decades moved more and more towards providing high-end instruments for research.
