Research Interest

Dr. Jr-Hau (J.H.) He put his efforts into the design of new nanostructured architectures for Nanophotonics and the next generation of nanodevices, including Photovoltaics (PV), and Resistive memory. He is also involved in directly observing resistive switching of memory device using in situ transmission electron microscopy (TEM) and electron beam lithography technique. In addition, he has been extensively working on PEC energy conversion applications including water splitting, CO₂ reduction (Solar Fuels)
