Welcome to professor Xiaodong Xu’s research group in the department of Physics and the department of Materials Science and Engineering at University of Washington.We are interested in understanding the optical, electronic, and quantum properties of novel solid state nanostructures by nanoscale device design, optical spectrosocpy, electrical transport, and scanning photocurrent measurements. Please click Research to learn more.

We have active research collabrations with the experimental groups of David CobdenAlex Jen, Ying Zheng, David Mandrous and the theoretical groups of Anton AndreevBoris SpivakChuanwei Zhang, Di Xiao and Wang Yao.
