Back Cover: Micropatterned ZnO rod arrays prepared by Au‐catalyzed electroless deposition (Phys. Status Solidi RRL 7/2014)

ZnO nanostructures represent an interesting choice for the fabrication of optoelectronic micro/nanodevices. In their Letter on pp. 648–652, Camelia Florica et al. were using easily scalable, low-cost and highly reproducible techniques such as photolithography and electroless deposition in order to prepare ZnO functionalized micropatterns for applications in sensing and self-cleaning surfaces. The morphological, structural, optical, wetting and electrical properties of the ZnO rods arrays were investigated. A conversion from hydrophilic to superhydrophobic was observed for the samples, depending on the ZnO substrate covering. A change in ZnO samples electrical resistance was evidenced from current–voltage measurements after their exposure to ammonia, such micropatterned ZnO rod arrays being effective for designing microdevices for potential applications in various areas where chemical sensing or superhydrophobicity properties are required.
