Fabrication of highly ordered and stepped ZnO comb-like structures

Growth and characterization of ultra-long ZnO nanocombs

“…The uniform comb teeth is clearly with length of more than 25 µm compared to the one reported from one hundred nanometers to ten micrometers. 7,8 Compared to group 1 and group 2, ZnO protuberances grow into uniform nanocomb teeth. It indicates the increment of carrier gas flow rate can effectively enhance the growth of ZnO nanocombs.…”

“…The growth of ZnO branches was believed to be related to the unique structure characteristic of wurtzite family. 7,9 When synthesis temperature increases from 650…”

Annealing effect on the morphologies and photoluminescence properties of ZnO nanocombs

“…The Zn and O 2 partial pressure in the reaction chamber play a crucial role, and the Zn supersaturation is always needed for the formation of combs [12,13]. However, the study of the annealing effect on the properties of ZnO nanocombs is rare, which is significant for their potential applications in different conditions, although there is plenty of research focused on the annealing effect on the properties of other ZnO nanoscale materials [17][18][19][20][21].…”

“…One-dimensional ZnO nanostructures, such as nanowires [2], nanorods [3], nanobelts [4], nanorings [5], and nanosprings [6], have been reported, which have great practical potential applications in piezoelectric transducers, optical waveguides, varistors, chemical and gas sensors, and spin functional devices [5,7]. Recently, the ZnO comb-shaped nanostructure, a kind of self-assembled hierarchical nanostructures whose potential applications include nanoelectronics, optoelectronics, nanocomposites, and catalysts [8], have been fabricated by many groups [9][10][11][12][13][14][15][16]. Zhang et al [13] reported that by tuning the degree of supersaturation, the growth asymmetry can either be rationally utilized or broken to obtain single-or doublesided ZnO nanocombs.…”

Isothermal crystallization kinetic of ZnO thin films

“…Besides these interesting properties, there is a variety of deposition techniques [8][9][10][11][12] that enable the production of ZnO thin films with various microstructures, and the tailoring of their nanostructure shapes such as belts [13][14][15] rods [16,17], wire [18][19][20] simply by varying the deposition parameters. It is well argued that there is a close relationship between the material microstructure and its physical properties.…”
