What are the applications of scanning tunneling microscope?

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.
