Variable temperature cryogenic STEM shown by Noah from Cornell

Noah Schnitzer (Cornell) et al demonstrate the use of a cryogenic MEMS-based system that achieves intermediate cryogenic temperature. This allows for the first time atomic-resolution STEM imaging and picometer precision mapping as a function of temperature, a key capability for understanding the evolution of order. Even more impressive, the results here show that we can track order in the exact same field of view across temperature, registered unit cell to unit cell. This allows tracking of topological defects in charge order and how they lead to melting of order. Read the pre-print here.

Our lab demonstrates a novel liquid helium TEM capability

Our team has been working on a novel design that enables liquid helium cooling inside transmission electron microscopes. This long-sought capability is key to accessing quantum phenomena but had proven difficult to achieve. Using a novel design, we demonstrate ultra-cold TEM performance (23 K), impressive millikelvin temperature stability, and low vibrations that enable atomic resolution TEM imaging.
