Dear Teachers and Students,
The Instrumentation and Service Center for Physical Sciences (ISCPS) will host a lunch seminar titled "Cold Field Emission Scanning Electron Microscope: Principles, Operation and Applications" on Tuesday, May 26, 2026. Teachers and students who are interested are warmly welcome to register and attend.
Date & Time: Tuesday, May 26, 2026, 11:40- 13:00
Venue: Classroom E10-205, Yungu Campus
Topic: Cold Field Emission Scanning Electron Microscope: Principles, Operation and Applications
Speaker: Sufang Wu, Service Engineer
Host: Dr. Ying Nie
Language:Chinese
Introduction:
Cold Field‑Emission Scanning Electron Microscope (Hitachi SU8600 and SU8230) integrates advanced electron optics and intelligent detection technologies. Equipped with a high‑performance cold field‑emission electron gun, it features high electron‑beam brightness and stable beam current, enabling ultra‑high‑resolution observation. It achieves a resolution of 0.7 nm even at a low accelerating voltage of 1 kV. Non‑conductive and beam‑sensitive samples can be clearly observed without gold sputtering, effectively avoiding charging effects and electron‑beam damage. Featuring intelligent operation, a stable vacuum system and excellent low‑voltage imaging performance, it is user‑friendly and reliable in operation. It meets high‑precision research requirements as well as industrial quality inspection and failure analysis needs, serving as a core analytical instrument in materials science, semiconductors, nanotechnology, biomedicine and other fields.
