Role of Al doping in structural, microstructural, electrical and optical characteristics of as-deposited and annealed ZnO thin films

Abstract

Aluminium dopant segregation from AD-xAZO thin films on annealing is established by structural, optical and electrical characterizations.

The influence of Al doping on the photocatalytic activity of nanostructured ZnO: The role of adsorbed water

“…This occurrence, known as the Burstein-Moss effect [38], justifies the enhanced conductivity of these samples with respect to ZnO reported in literature [39] and explains the hereby observed opto-electronic behavior of the Al-doped samples. Interestingly, Shinde et al [22] reported that a similar blue shift observed in pulsed-laser deposited Al doped ZnO thin films disappeared upon annealing of the samples at 800°C.…”

“…Different preparation methods such as coprecipitation [18], spray pyrolysis [19], sol-gel [20], hydrothermal routes [21], pulsed-laser deposition [22], and combustion [23] have been used. Some papers focus on the optical features of Al modified ZnO, indicating them as the key factors for the improved photocatalytic activity.…”

Non-fluorinated superhydrophobic and micro/nano hierarchical Al doped ZnO film: the effect of Al doping on morphological and hydrophobic properties

“…6 Therefore, increasing attention is drawn to fabricating superhydrophobic surfaces without any low energy organic materials, such as inorganic material lms with specic hierarchical rough surfaces. 15,16 However, few studies have reported how doping can affect the superhydrophobic properties of the surface. Recently, with the development of optoelectronic devices, the surface wettability of ZnO and its metal doping oxide has aroused great interest and been realized by combination of the micro-nanostructured topography and low surface energy.…”

Strong Volta potential change in doped zinc oxide as a photoresponse to UV irradiation

“…The effect of band gap blue-shiing may be attributed to the Burstein-Moss effect, 31 which was already observed in previous studies of doped ZnO lms. 19,32,33 3.5. SKP-measurements SKP measurements with 10 minutes automated on/off illumination cycling are shown in Fig.…”
