UW Researchers Build Energy Efficient Nanolaser

University of Washington scientists have built a new nanometer-sized laser — using the thinnest semiconductor available today — that is energy efficient, easy to build and compatible with existing electronics. The ultra-thin semiconductor is about 100,000 times thinner than a human hair.

CEI faculty member Xiaodong Xu and graduate fellow Sanfeng Wu published their research in the March 16, 2015 edition of Nature.  Read more at UW Today: UW scientists build a nanolaser using a single atomic sheet.


“Providing clean energy to the inhabitants of our planet is a major challenge to future generations. The University of Washington is to be congratulated for establishing an Institute where faculty and students can work together to tackle the difficult global challenge of energy sustainability.”
– Mildred Dresselhaus, Professor of Physics and Electrical Engineering, Emerita and Institute Professor, Massachusetts Institute of Technology
“Energy competition is opening up in a variety of ways, the push for carbon control will continue, and the rate of technology advancement is exponential. All the things I’ve seen at the CEI are just perfect for the way we see things going in energy. You guys are at the cutting edge. We’re counting on you.”
– Ronald Litzinger, President, Edison Energy
