PICO-RHEED
Low Emission Reflection High-Energy Electron Diffraction
Product Information
The PICO-RHEED allows crystal structure analysis of organic thin films because of enabling use with low-emission current.
PICO-RHEED can significantly reduce sample damage caused by electron beams due to low -emission current, while enabling observation of high-brightness reflection electron diffraction images by using a dedicated MCP screen.
By replacing the MCP screen with a standard (optional), PICO-RHEED can be used as a standard RHEED to analyze inorganic thin films.
Features
- Significantly reduced sample damage (1/500 to 1/2800: in-house comparison)
- Variable bias for Wehnelt electrode
- High reliability due to low noise and high stability output
- Compatible with kSA400 RHEED image/video analysis system
