Our lab utilizes scanning transmission electron microscopy (STEM) to understand the physical properties of oxides by structural, and chemical analysis at the picometer-scale. Additionally, with our technique to achieve thin, freestanding membranes of various materials, we aim to explore new phenomena from 3D materials when reaching their 2D-like state.
