A research team led by professor YU Shuhong at the University of Science and Technology of China (USTC) has reported a new class of heteronanostructures they term axial superlattice nanowires (ASLNWs), which allow large lattice-mismatch tolerance and thus vast material combinations. The research article entitled ''One-Dimensional Superlattice Heterostructure Library'' was published in Journal of the American Chemical Society on May 12th.
