High‐Yield Synthesis of Single‐Crystal Nanosprings of ZnO

Pre-growth pressure control in a solid–vapor process leads to the synthesis of single-crystal ZnO nanosprings at high yield (>50 %). This study demonstrates the possibility of synthesizing nanosprings (see image) of high purity and at high yield, and makes systematic understanding of the properties and exploration of the applications of semiconducting and piezoelectric ZnO nanosprings achievable.
