Associate Professor University of Notre Dame USA


Dr. Xinyu Liu received his undergraduate education in the University of Science and Technology of China (USTC). In 1996, after he completed his Bachelor’s and Master’s degrees in Physics at USTC, he came to United States and entered Ph.D. program in physics at the University of Notre Dame, where he worked with Prof. Jacek K. Furdyna on developing new magnetic semiconductor materials by molecular beam epitaxy (MBE). After he received his Ph.D. in Physics in 2002, he continued working at Notre Dame. He was promoted to the rank of Research Assistant Professor in 2005, then Research Associate Professor in 2013. He has published over 300 papers and 4 book chapters. These articles have earned him over 3800 citations and an h-index of 37. His research is currently centered on studies of spin-based phenomenon in quantum materials. He is a specialist on developing, fabricating, and characterizing integrated nanostructures grown by MBE.
