researchers at the college have improved on low-energy electron microscopy (LEEM) and photoemission electron microscopy (PEEM), both of which harness low-energy electrons (up to 100 electron volts).

Prof. Dan Shechtman of the Technion–Israel Institute of Technology made the discovery that would later earn him the 2011 ...

This finding confirms that quasicrystals are shaped by hidden higher-dimensional physics, not just random patterns. A ...

The photoemission electron microscope (cone-shaped instrument at top) examines the rapid movements of the electrons.

Ultrahigh vacuum and surface preparation techniques. Principles of surface analytical techniques, including Auger electron spectroscopy, photoemission, low energy electron diffraction, energy loss ...

Looking into the vacuum chamber of the Photoemission Electron Microscope in Lund: The research team used a similar device to study electrons that had been released from a sample using laser pulses.

Wiebke Bennecke, a physicist at the University of Göttingen and first author of the study, explains, "Using our photoemission electron microscope, we can recognize that the attractive forces ...

Photoemission is a process during which electrons are ejected from a metal surface when exposed to electromagnetic radiation, (eg ultraviolet). If a clean, positively charged zinc plate is exposed ...

The High Resolution Transmission Electron Microscopy (HRTEM) Facility at the University of Wyoming features the powerful FEI Tecnai G2 F20 200 kV (S)TEM to meet the characterization needs of the ...
