Characterization of m-plane ZnO thin film on γ-LiAlO2 (100) substrate by metal-organic chemical vapor deposition

Template Effects of Microstructure and Property of Sol–Gel-Deposited ZnO:Al:Mo Films

“…Crystal anisotropy can lead to optical anisotropy, thereby increasing blueshift and light transmittance of ZnO:Al:Mo films. This phenomenon has also been reported in previous studies [16][17][18]. That is, the c-oriented and parallel arrayed film has greater polarized optical transmittance and blueshift parallel with than perpendicular to the c-axis.…”

“…Furthermore, it is well-known that one-dimensional nanostructure and its reasonable array can induce special behavior for the materials and enhances certain electrical, optical, and mechanical properties of the materials. In this aspect, c-oriented ZnO films parallel to the substrate plane [11,12] or randomly arrayed on the substrate have shown wider band gap and stronger transmittance than randomly oriented films [13,14]. To induce onedimensional nanostructure, some long-chain organic molecules are generally used as template.…”

Study of structural and optical properties of sprayed WO3 thin films using enhanced characterization techniques along with the Boubaker Polynomials Expansion Scheme (BPES)

“…In the same line, the deposited films showed a relatively high absorption coefficient of around 10 4 cm −1 and exhibited a direct transition gap which lies within 2.6-3.6 eV domain. It has been found that these materials were n-type and electrical measurements are in progress in order to reach the resistivity of such thin films [32][33][34][35][36][37][38][39][40][41]. This result is very encouraging since a costless and simple spray pyrolysis technique can be used to prepare such oxides and open the way of possible valorisation of the prepared films in many optoelectronic applications.…”

Annealing effects of co-doping with Al and Sb on structure and optical–electrical properties of the ZnO thin films

“…ZnO thin films have been prepared by various methods such as RF magnetron sputtering [5], molecular beam epitaxy (MBE) [6], metal organic chemical vapor deposition (MOCVD) [7], pulsed laser deposition (PLD) [8], spray pyrolysis [9] and the sol-gel process [10]. The ZnO thin films doped with some elements and prepared by sol-gel technique have now been especially paid attention owing to its advantages such as low cost, simple deposition procedure, easier composition control, low processing temperature, easier fabrication of large area films.…”
