The Pan Research Group at the University of California, Irvine specializes in atomic-scale characterization and measurement using such techniques as ultra-high resolution transmission electron microscopy and in-situ microscopy where electrical and chemical experiments are conducted while being imaged in TEM, as well as scanning probe measurements, photoluminescence, and other techniques. Our research has applications in electronics, photovoltaics, ferroelectric memories and devices, catalysis, particularly for automotive applications, and lithium battery cathode materials.
