Facile synthesis of well-aligned ZnO nanowire arrays and their photoluminescence properties

Aging effects on the optical properties of an individual Zn-rich ZnO nanowire

“…The optical properties of ZnO nanowires have attracted considerable attention because of its near-bandedge (NBE) ultraviolet (UV) emissions and potential applications in nanolasers and UV detectors [11][12][13][14][15][16][17]. Most of the researches have focused on the enhancement of UV emissions and decrease of deep-level (DL) emissions.…”

Mechanical responses of single-crystal ZnO

“…ZnO has been advocated as one of the prominent materials for next-generation optoelectronic applications owing to its wide band gap (3.37 eV), high exciting binding energy (60 meV) and optical gain (300 cm −1 ) [1][2][3]. In addition, the lower growth temperatures required, as compared to GaN, has further made it more advantageous.…”

Modulating the shape of ZnO nanostructures grown by using thermal chemical-vapor deposition

“…Notably, thermal chemical-vapor deposition (CVD) is a powerful method because of its ability to produce ZnO nanostructures with high crystallinity, various morphologies, and low chemical contamination [6,7]. Several growth parameters affecting the ZnO nanostructures during thermal CVD have been widely explored, including the temperature [8], partial oxygen pressure [9], cat- * E-mail: seonglim@skku.edu † E-mail: mjeong@skku.edu alysts [10], growth time [11], and source materials [12]. However, changes in the shape of the ZnO nanostructure, i.e., the formation of nanowires, nanospears, nanowalls, and nanorods, in relation to the distance between the reactant and the substrate have not been systematically investigated yet.…”
