Research Description

Dr. Chang runs a lab in the Department of Physics at The Pennsylvania State University.

Dr. Chang is a world-leading expert in the molecular beam epitaxy (MBE) growth of quantum materials. Chang was the first to realize the quantum anomalous Hall (QAH) effect in 2013 by developing MBE growth of a magnetically doped topological insulator thin films. In addition, Chang has played a crucial role in the discovery and understanding of a variety of other important physical phenomena such as the axion insulator state in quantum materials. His recent interests include the pursuit of high temperature and high Chern number QAH insulators and the exploration of Majorana physics in the QAH-superconductor hybrid structures.

Dr. Chang has won numerous awards, including NSF CAREER Award (2019), Macronix Prize (2019), ARO-Young Investigator Program Award (2018), Alfred P. Sloan Research Fellowship (2018), and IUPAP Young Scientist Prize (2016).

Dr. Chang earned his Ph.D. from Tsinghua University in China.
