Synthesis of Aligned ZnO Nanorod Array on Silicon and Sapphire Substrates by Thermal Evaporation Technique

Effect of microwave power on energy gap of ZnO nanoparticles synthesized by microwaving through aqueous solutions

“…Differrent morphologies of ZnO structures such as nanorods [1][2][3], nanowires [4,5], hollow spheres [6], hammershaped particles [7], nanocubes [8], nanoparticles [9,10], tetrapod [11], nanotubes [12,13] and nanocrystals [10,14] have been synthesized by both chemical and physical methods: sol-gel process [15][16][17], hydrothermal process [18][19][20], thermal evaporation [3,7,9,11], chemical vapor deposition (CVD) [6,21,22], ultrasonicassisted synthesis [8,14,23] and microwave radiation [24][25][26][27].…”

Catalyst-free growth of one-dimensional ZnO nanostructures on SiO2 substrate and in situ investigation of their H2 sensing properties

“…However, metallic catalyst is often used in the synthesis process and it is very difficult to remove its residues completely, which will heavily affect the investigation of their application properties. Although some catalyst-free methods have been developed on sapphire or Si substrate [25,26], little work has been done about catalyst-free growth of 1D ZnO nanostructures on SiO 2 substrate which is compatible with semiconductor technology.…”

Effect of H2O2 concentration on electrochemical growth and properties of vertically oriented ZnO nanorods electrodeposited from chloride solutions

“…For these reasons, ZnO is considered as a good candidate for optical devices in the near UV region [8], and for the short wavelength-emitting devices such as light emitting diodes [2]. ZnO with different morphologies can be prepared by various deposition techniques such as magnetron sputtering [9], chemical vapour deposition [10], pulsed laser deposition [11], spray pyrolysis [12] or thermal evaporation [13] and so on. Among all approaches, electrodeposition technique has been emerging as a competitive technique for the fabrication of metallic oxide semiconductor nanostructures with different shape and sizes [14][15][16][17].…”
