Preparation and characterization of highly transparent and conductive indium-zinc oxide thin films deposited by pyrolysis spray technique

Abstract

Ternary compound films of ZnO-In 2 O 3 system were prepared by spray pyrolysis method. The films were deposited on heated glass substrates by pyrolytic decomposition of zinc chloride and indium chloride in distilled water with different ratio x of [Zn] In]). The phase change, chemical composition, electrical and optical properties of the Zn-In oxides were investigated over wide range of ratio x. Quasi-amorphous sub-oxide films with thickness of 200-400 nm were first obtained, the films were then annealed in Argon atmosphere at 550°C for 1 h. To optimize the physical properties of sprayed ZnO-In 2 O 3 thin films, we carry out on a systematic study of their microstructural characterization and transport properties. Continuous

Enhanced optical third-harmonic generation in phase-engineered nanostructured Zn1−x Cd x S thin films for optoelectronic device applications

“…Various methods are utilized for thin film deposition, encompassing spin coating, spray pyrolysis, sputtering techniques and thermal evaporation etc [8][9][10][11]. Furthermore, the introduction of impurity ions can have a significant impact on the electronic structure and transition probabilities.…”

Effect of annealing temperature and capping ligands on the electron mobility and electronic structure of indium oxide nanocrystal thin films: a comparative study with oleic acid, benzoic acid, and 4-aminobenzoic acid

“…Measurement of band onsets in NC solids can be performed by using optical methods such as UV-visible spectroscopy [17][18][19] or photoluminescence spectroscopy (PL). 20,21 However, with these techniques, the bandgap energy value can only be determined from the energy difference between the conduction band (CB) and the valence band (VB) when they are both known and their exact locations are unknown.…”

The effect of copper doping on the structural, optical, and electrical properties of cadmium oxide thin films using the spray pyrolysis technique

“…Electrical and optical properties are more significant in metal oxides such as cadmium oxide (CdO), tin oxide (SnO 2 ), indium oxide (In 2 O 3 ), titanium oxide (TiO 2 ), zinc oxide (ZnO), and nickel oxide (NiO), this issue has never escaped the attention of optoelectronic industries (Benhaliliba, et al 2012;Dounia, et al 2016;Ramarajan, et al 2020;Şahin 2019). CdO is an important II-VI semiconductor with an n-type high electrical conductivity of ~10 2 -10 4 S/cm thanks to its native defects and good transparency, especially in the NIR spectral region, with a direct bandgap of 2.2-2.7 eV depending on the deviation from the ideal CdO stoichiometry (Zargar, et al 2020).…”
