C-Flat and Au-Flat provide the ideal specimen support to achieve high-resolution data, making it the perfect choice for single particle analysis and cryo-tomography

CD-Flat is the premier transmission electron microscopy sample support for automated S/TEM imaging and metrology

Cryo Electron Microscopy

Researchers report that the ultra-flat surface of C-flat leads to thin ice and uniform particle distribution, enabling superior data collection compared to other support films.


Measuring critical dimensions of transistor gate structures and other semiconductor thin films requires TEM-based metrology. C-Flat provides a regular array of analysis sites covered with a thin, amorphous sample support, features that are required for automated CD-TEM characterization.
