Cold Field Emitters

By Applied Physics Technologies

We grow and process our own single-crystal tungsten in-house. Our etch processes can be tailored to customers’ requirements and are tightly controlled to guarantee quality and consistency.

CeBix®(100) 1.0 mm Top Hat Cambridge MVM

Low work function CeBix®(100), 2.5 eV Lifetimes of up to 5000 hours reported Lower volatility than LaB 6 Top-hat geometry on mini-Vogel mount (MVM) Sample Operation Data: Lowest heat setting where beam is stable, vacuum <10-6 torr

Thermal Field Emitters

Our zirconiated tungsten thermal field emitters (ZrOW TFE), are the industry-standard for applications requiring high brightness, improved spatial resolution, stable emission, and long life.

Thermionic Emitters

We grow and fabricate our own high-quality, single-crystal LaB6 and CeBix® in-house using a process that produces the purest and lowest work function material commercially available.

Electron Sources

Our deep knowledge of the physics of electron emission stems from decades of basic research and electron source development.
