Scanning Tunneling Microscope reveals the location of every atom on the surface, as well as every single atomic defect in the field of view.
Ever since the 1980s, when Gerd Binnig of IBM first heard that «beautiful noise» made by the tip of the
first scanning tunneling microscope (STM) dragging across the surface of an atom, and he later developed the atomic force microscope (AFM), these microscopy tools have been the bedrock of nanotechnology research and development.

But the only way we knew how to make new individual skyrmion bubbles on demand was at very, very low temperatures (below -450 degrees Fahrenheit) with expensive equipment like spin -
polarized scanning tunneling microscopes — not practical for making consumer devices like laptops, and not even easy for most scientists to make so they could study them.
The Theory Prize was given for research into diamond nanoparticles; the Experimental Prize was given for development
of scanning tunneling microscope (STM) technology.
They proposed a new way to study a cuprate, one that no other group had tried: a powerful imaging technique developed by Davis, called sublattice imaging - which is performed using a
specialized scanning tunneling microscope (STM) capable of determining the electronic structure in different subsets of the atoms in the crystal, the so - called sublattices.
It took him 18 months to build the low temperature, ultra high
vacuum scanning tunnelling microscope (STM) that he used to claim his place in history as the first person ever to move and control a single atom.

The scanning tunnelling microscope measures changes in electrical current between the probe tip and the atoms on a sample surface.
The OIST scientists used a single crystal of methylammonium lead bromide (CH3NH3PbBr3) to create topographic images of its surface with
a scanning tunneling microscope.
Scanning tunneling microscope images also reveal local imperfections caused by dislocations of molecules and ions and, probably, missing atoms.
Heinrich used
a scanning tunneling microscope to align the iron atoms so each one takes on a magnetic polarity opposite that of its neighbor.

Designed by Tufts University chemist Charles Sykes, the motor runs on energy from
a scanning tunneling microscope, which normally reads the shape of a surface by moving a thin metal stylus across it.
Juan Carlos Cuevas at the Autonomous University of Madrid in Spain and his colleagues modified
a scanning tunnelling microscope — which allows the manipulation and imaging of atoms — to trap a ring of benzene between the probing tip of the microscope and a flat gold surface.

a scanning tunneling microscope (STM), in which a sharp needle probes the atoms of a surface, one by one.
They first isolated a buckyball on a metal surface with
a scanning tunneling microscope (STM), which images the atomic contours of a surface by measuring changes in the electrical current that travels between the surface and an ultrasharp tip that scans across it.
A non-metal track should allow the engine to work, but this makes observing the car in action problematic as
the scanning tunnelling microscope normally used needs a metal base.
Working at a temperature of four degrees Kelvin, the researchers used
a scanning tunnelling microscope (STM) to arrange vacancies in a single layer of chlorine atoms supported on a copper crystal.
The revolution began quietly in 1981, when Gerd Binnig and Heinrich Rohrer at IBM in Zurich invented
