Researchers carefully positioned lasers to compress billions of electrons together, creating a beam five times more powerful ...

The cold cathode field emission (FE) tip can become contaminated by gas particles in the system, deteriorating the quality of the electron beam. Therefore, the tip is "flashed", or quickly heated to a ...

These e-beam lithography experiments follow on from [Zach]’s earlier research using lasers. Homebrew IC expert Sam Zeloof has also used electron beams in his work. Thanks for the tip ...

A team of physicists at the SLAC National Accelerator Laboratory, in Menlo Park, California, generated the highest-current, highest-peak-power electron beams ever produced. The team has published ...

This tip is made of a sharply edged piece of mono-crystalline ... This unique lens focuses the beam onto the sample and helps the condenser lenses narrow the electron beam. The lens on our FE-SEM is a ...

A beam of electrons is produced at the top of the microscope by an electron gun. The electron beam follows a vertical path through the microscope, which is held within a vacuum. The beam travels ...

At the beginning of an experiment, a beam of electrons may have a rest energy of 1/2 million electron volts; it is directed through a linear "pre-accelerator" (or "injector") where the energy is ...

Newly achieved precise control over light emitted from nanodots embedded in two-dimensional (2D) materials could lead to ...
