A cryogenic scanning transmission electron microscopy (cryo-STEM) study reveals the phenomenon of inverse melting in Zr-doped BaTiO3.

A cryogenic scanning transmission electron microscope reveals the atomic-scale mechanism that disrupts the charge-ordered state in a manganite material. The visualizations were performed at the atomic scale and across variable temperatures. This work by Noah Schnitzer was published in Physical Review X.

Following initial demonstration of a novel liquid helium flow cryogenic TEM holder in 2023, our team assembled subsequent prototypes that have shown sub-Angstrom HRTEM imaging, low sample drift (less than 0.4 Angstrom per second), and low millikelvin-level temperature fluctuations.
