A new analysis reveals what happens when very short or narrow electron beams encounter a particle. The research is published ...

Physicists have proposed a way to extract the internal quantum states of electron wave packets by analyzing how those packets ...

Working on the nanoscale for manufacturing poses some unique challenges. While many macroscale manufacturing methods such as lithography and additive manufacturing have been successfully translated ...

An electron microscopy image can capture atoms arranged in a crystal lattice or defects threading through a semiconductor ...

STEM operates by focusing a beam of electrons into a narrow probe that is scanned across a thin specimen. As the electrons interact with the sample, they are either scattered or transmitted. The ...

Our ability to image the subatomic realm is limited, not just by resolution, but also by speed. The constituent particles that make up – and fly free from – atoms can, in theory, move at speeds ...

TEM works by accelerating electrons, typically with energies between 80 and 300 kV, and directing them through a specimen thin enough for electron transmission. Because of their very short wavelength ...

Using a nanomanipulator and an ultra-fine ion beam, a tiny lamella, about five by ten micrometres in size and only one hundred nanometres thin, is cut out of the meteorite and attached to a sample bar ...

With the inventions of transmission electron microscopy (TEM) in 1931 and scanning electron microscopy (SEM) shortly after in 1937, scientists gained an unprecedented ultrastructural view of the ...
