Synthesis of ZnO nanorods for acoustic wave sensor

High-performance ultraviolet radiation sensors based on zinc oxide nanorods

“…Vapor phase growth methods such as chemical vapor deposition [13], metal-organic chemical vapor deposition [14], physical vapor deposition [15] and molecular beam epitaxy [16] are well developed and often applied for the synthesis of high quality metal and metal oxide nanomaterials. Solution based methods provide the formation of nanostructures with different morphologies and structures by self-organization at the low-temperature chemical [17,18] and electrochemical [19,20] processes without expensive vacuum and other microelectronic technologies. While electrochemical growth allows obtaining well-aligned ZnO nanorods on the conductive films the low-temperature hydrothermal synthesis is suitable for synthesis of nanostructures with different shapes almost on any substrates.…”

Peculiarity of seed-layer synthesis and morphometric characteristics of ZnO nanorods

“…Among complicated and expensive traditional fabrication techniques such as VLS [3] and MOCVD [4], low-temperature synthesis methods of single-crystalline ZnO nanostructures become more accepted. While electrochemical lowtemperature growth [5] allows obtaining well-aligned ZnO nanorods on the conductive films the combined with sol-gel technique hydrothermal method is suitable for nanostructures synthesis almost on any substrates. The hydrothermal method has following advantages: low-cost, ease handling, scalability, opportunity to form various structures subject to process parameters.…”

“…In comparison with electrodeposition technic, which is described in [5], it should be noticed that deposition of seed-layer has allowed formation of separated single ZnO nanorods but tilted due to the roughness of seed-layer, when in the case of electrodeposition on metal-coated LiNbO 3 substrates overgrowth at the roots of ZnO nanorods is occurred. It is expected that vertically oriented ZnO structures can be obtained on smooth seed-layer, formed at adjusted process parameters such as sol-gel concentration and annealing temperature.…”

Experimental evaluation of ZnO nanowire array based dynamic pressure sensor

“…ZnO nanostructures with tailor-made properties can be fabricated using controlled synthesis approaches. Various bottom up approaches like chemical bath deposition (CBD) [2,[13][14][15][16], electrodeposition [19,20], vapour liquid solid (VLS) method [1,[3][4][5], chemical vapour deposition (CVD) [2,4,11,13] and physical vapour deposition (PVD) [13] are reported in literature for the synthesis of ZnO nanowires. Vapour phase growth methods (VLS, CVD & PVD) are complex due to the requirement of high vacuum and high temperature.…”
