Chiral crystals are sought after for their ability to tune the polarization of light. Now, multiwalled boron nitride nanotubes (BNNTs) are shown to be promising chiral crystals with coherently stacked structures, wherein the component tubes display mono-chirality, homo-handedness and unipolarity. This unique architecture endows BNNTs with strong optical nonlinearity and a chiral geometry-dependent chiroptical response.
