Electrical and gas sensing properties of ZnO nanorod arrays directly grown on a four-probe electrode system

Low temperature synthesis of hexagonal ZnO nanorods and their hydrogen sensing properties

“…HMTA, which was used in the synthesis of ZnO nanorods, provides the hydroxide ions (OH À ) and also ammonia molecules (NH 3 [25]. Formation of the two complexes can be described as follows: Thus, two reactions can take place under described conditions in the aqueous solution, resulting in the formation of ZnO.…”

“…Metal-oxide nanostructures have attracted considerable attention due to their small dimensions, low cost, and high compatibility compared to Si-based microelectronics [1][2][3][4][5]. Among them, ZnO is an interesting chemically and thermally stable n-type semiconductor with a large exciton binding energy of 60 meV and large band gap energy of 3.37 eV at room temperature.…”

“…Among these metal oxides, ZnO has been identified as one of the preferred materials because of its excellent gas sensing properties. ZnO (1D) nanostructure based sensors have been reported to show good sensing properties such as low detection limit, good selectivity, and short response and recovery time [3,6].…”

Size-dependent Bacterial Growth Inhibition and Antibacterial Activity of Ag-doped ZnO Nanoparticles under Different Atmospheric Conditions

“…Its high exciton binding energy even at high temperature provides excitonic emission as good as at low temperature [4] . This semiconductor has several applications such as transparent conductive coatings [5] , electrodes for dyesensitized solar cells [6] , gas sensors [7] , field emission materials [8] , antimicrobial agents, electrical devices and in gas sensors [9] . In addition, ZnO nanoparticles also possess huge technological importance.…”

Fabrication of well-aligned and dumbbell-shaped hexagonal ZnO nanorod arrays and their dye sensitized solar cell applications

“…ZnO 1D nanostructures have received extensive interest in room-temperature ultraviolet (UV) lasers, chemical sensors, electronic devices, photodetectors and dye-sensitized solar cells (DSSCs), etc. [1][2][3][4][5][6][7][8][9][10][11]. The properties of ZnO nanostructures robustly depend on their dimensions and morphologies.…”
