In-situ electron microscopy and ptychography

Imaging materials under heating, biasing, light and cryogenic conditions, with ptychography on EMPAD and Gatan K3 detectors.

We have built capabilities to image materials under a range of external stimuli:

This is just the beginning. We plan to grow these capabilities through collaborative projects and new funding opportunities. Collaborate with us.
