Real-time transport properties of materials observed at cryogenic temperature

There has been a significant scientific interest in studying material transport behavior at cryogenic temperature in real-time. Hummingbird Scientific’s Cryo Biasing TEM holder allows researchers to concurrently cool their sample to liquid nitrogen (LN2) temperatures and apply electrical stimuli. This new capability shows promise in the study of quantum materials with high Curie temperatures (Tc) and degradation behavior of batteries at extreme environmental conditions.
