On page 7603, X. Huang and co‐workers report a direct transformation of wurtzite‐structured bulk crystals to single‐crystalline crystallographically oriented semiconductor nanowire arrays via one‐step heating in an Ar/H 2 atmosphere. Real‐time imaging during in situ environmental SEM experiments reveals that the nanowire arrays form through a selective vaporization process that is related to the crystallography of the wurtzite crystals. The prepared nanowire arrays are of high quality, giving rise to the good performance of the constructed photodetectors.
