  • 冷却 LLZ-1

Atomic resolution STEM image observation of LLZ(Li7La3Zr2O12),which is degraded by exposure to air(moisture) and weak to electron beam with lithium ion material, was successful.
From this result, it was proved that the non-exposure(Transfer) was successful, and the crystal orientation was adjusted by Y tilt,and the electron beam damage was reduced by cooling of -160°C.

 

- Reasons for high-resolution image at -160°C -

We realized it with the following our special system.

  1. Mechanical drift cancellation mechanism from our patented technology
  2. High-precision temperature controller. Range is ± 0.005°C.
  3. Original Gonio cover for cryo tem holder

By making these into one system, it is possible to obtain much easier get the high resolution
image than current cooling holders.

  • Cryo vacuum transfer tem holder

As a result, the stability during cooling has improved, so we have successfully acquired EDS column map data.

Annotation: Observations using this holder are dependent on specific cooling conditions and are influenced by the TEM environment. Therefore, it cannot be guaranteed that identical data will be obtained in all environments.
