The nearly simultaneous Mott (electronic) and Peierls (structural) transitions in vanadium dioxide are of significant scientific interest and have tremendous technological promise in computing, memory, optics, and micromechanics. The cover features nanoscale-resolution maps of the Mott and Peierls transitions imaged simultaneously by Kumar et al. using state-of-the-art in situ STXM at the ALS. Article link.
