On page 5038 J. Q. Xu, T. Y. Zhai and co‐workers develop an effective chemical vapor deposition process to fabricate high‐quality NdB6 nanoneedles with an ultra‐low work function. These nanoneedles exhibit excellent field‐emission performance with a low turn‐on/threshold field, a high current density, and good stability. Such a simple synthesized procedure can be readily extended to the synthesis of RB6 (R = rare earth) and related boride nanostructures.
