“…ZnO thin films can be produced by several techniques like magnetron sputtering [10], reactive evaporation [11], pulsed laser deposition [12], sol gel technique [13] and spray pyrolysis [14]. Because of the advantages of low cost, simple processing, easy control of the film thickness and large range deposition temperatures, the spray ultrasonic is an extremely reliable technique for the deposition of thin films and is used in industry for large scale production.…”

“…However, B-doped ZnO, a semiconductor-like TCO, has higher resistivity and lower carrier concentration than does a metal-like TCO such as Ga-doped ZnO (GZO). Sn can also be used as a dopant in ZnO, where the Zn 2+ ion is replaced by the Sn 4+ ion, to increase the carrier concentration [19,20]. Compared with other TCOs, Sn-doped ZnO exhibits reduced conductivity owing to the high mean barrier height depending on disorder of grain boundary [21].…”

We have used a modified-intake plasma-enhanced metal–organic chemical vapor deposition (MIPEMOCVD) system to fabricate gallium-doped zinc oxide (GZO) thin films with varied Ga content. The MIPEMOCVD system contains a modified intake system of a mixed tank and a spraying terminal to deliver the metal–organic (MO) precursors and a radio-frequency (RF) system parallel to the substrate normal, which can achieve a uniform distribution of organic precursors in the reaction chamber and reduce the bombardment damage. We examined the substitute and interstitial mechanisms of Ga atoms in zinc oxide (ZnO) matrix in MIPEMOCVD-grown GZO thin films through crystalline analyses and Hall measurements. The optimal Ga content of MIPEMOCVD-grown GZO thin film is 3.01 at%, which shows the highest conductivity and transmittance. Finally, the optimal MIPEMOCVD-grown GZO thin film was applied to n-ZnO/p-GaN LED as a window layer. As compared with the indium–tin–oxide (ITO) window layer, the n-ZnO/p-GaN LED with the MIPEMOCVD-grown GZO window layer of the rougher surface and higher transmittance at near UV range exhibits an enhanced light output power owing to the improved light extraction efficiency (LEE).

Al doped and un‐doped ZnO thin films are coated on glass substrate by successive ionic layer adsorption and reaction technique with varying doping concentrations of Al from 3 to 7 at%. The samples are annealed at 450 °C for 1 h in the air. The structural and morphological analysis of the samples are carried out using XRD and SEM. The samples are irradiated with high energy electron beam at a dosage of 5 kGy and its sensing properties are explored. It is observed that the irradiated samples show an enhanced sensitivity to liquefied petroleum gas than that of unirradiated samples at the same doping concentration. The higher response and recovery time of irradiated samples are compared with unirradiated samples. The maximum sensitivity (S = 0.35) with faster recovery time of 25 s is observed for the 7% doped Al‐ZnO thin irradiated film.
