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).

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

This schematic depicts the time-resolved photoemission electron microscopy instrumentation that allows a Femtosecond Spectroscopy Unit to visualize electron movements. The 800nm pump pulse (red) ...

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 ...

Magnetism plays a crucial role in enabling various applications, ranging from memory storage devices to advanced medical imaging, energy-efficient electric motors, magnetic sensors, and emerging ...

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

Scientists have developed a tiny flower-shaped structure that’s made of a nickel-iron alloy to concentrate and locally ...
