Grids for Applications in High-Temperature High-Resolution Transmission Electron Microscopy
New TEM grids coated with ultrathin amorphous Al2O3 films have been developed using atomic layer deposition technique. The amorphous Al2O3 films can withstand temperatures over 600∘C in air and 900∘C in vacuum when the thickness of the Al2O3 film is 2 nm, and up to 1000∘C in air when the thickness i...

| Summary: | New TEM grids coated with ultrathin amorphous Al2O3 films have been developed using atomic layer deposition technique. The amorphous Al2O3 films can withstand temperatures over 600∘C in air and 900∘C in vacuum when the thickness of the Al2O3 film is 2 nm, and up to 1000∘C in air when the thickness is 25 nm, which makes heating TEM grids with nanoparticles up to 1000∘C in air and immediate TEM observation without interrupting the nanoparticles possible. Such coated TEM grids are very much desired for applications in high-temperature high-resolution transmission electron microscopy. |
