Real-time transport properties of materials observed at cryogenic temperature

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