Another milestone in the understanding of 2D semiconductors. S. Barja (Berkeley) , M. M. Ugeda (CIC Nanogune) et al. have observed the formation of one-dimensional charge density waves along mirror twin boundaries in MoSe2. This research opens the door to the study of charge transport in this type of materials.
Sadly, the picture didn’t make it to the cover of Nature Physics, but both the research and the picture are beautiful enough to show off a little.
