Unlocking the World's Smallest Details: Scanning Tunneling Microscopy (STM)

Are you fascinated by the mysteries of the microscopic world? Do you want to explore the secrets that lie at the heart of atomic structures? Look no further than Scanning Tunneling Microscopy (STM), a revolutionary technique that has enabled scientists to visualize and manipulate individual atoms with unprecedented precision.

What is STM?

Scanning Tunneling Microscopy is an advanced microscopy technique that uses a sharp probe, called a tip, to "feel" the surface of a material at the atomic level. The tip is brought into close proximity with the surface, creating a tiny gap (or tunnel) between them. By measuring the current flowing through this tunnel, scientists can create high-resolution images of the surface topography, revealing even the smallest details.
