Heterostructures formed by different three-dimensional semiconductors form the foundation for contemporary electronic and photonic devices. Now,University of Washington scientists have successfully combined two different ultrathin semiconductors—each just one layer of atoms thick and roughly 100000 times thinner than a human hair—to make a unique two-dimensional heterostructure with potential uses in clean energy and optically-active electronics. The team, led by Boeing Distinguished Associate Professor Xiaodong Xu, and announced its findings in a paper published Feb. 12 in the journal Science.
