TRANSISTOR 1 (IMAGE) Rice University Caption Scientists have achieved the long-sought goal of growing an ideal hexagonal boron nitride crystal by taking advantage of disorder among the meandering steps on a copper substrate, as reported in Nature. The random steps keep the hBN in line and make it useful as a dielectric for two-dimensional electronics.
