The scanning electron microscope has many advantages over traditional microscopes ... Argon gas and an electric field cause an electron to be removed from the argon, making the atoms positively ...

But the basic task in atomic-resolution TEM is not that of calculating how scattering from atoms affects the electron wavefunction, rather the opposite: inferring the atomic structure from the ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

The FEI 200kV Titan Themis Scanning Transmission Electron Microscope (STEM) is a scanning transmission electron microscope with several key capabilities. This microscope positions Michigan Tech ...

In electronics work, the scanning electron microscope (SEM ... Armed with a STEM, you can even see the shadows of atoms.

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that ... quantum is the electron." It is the same idea used in CT scans used in medicine ...

experiment in a scanning transmission electron microscope (STEM). An electron gun at the bottom fires high-energy electrons, which are refined by lenses and an aberration corrector for precision.

By using an electron beam, or e-beam ... The e-beam is focused to a point smaller than the distance between atoms and scans across the material to create an image with atomic resolution.
