“…Moreover, single significant (100) diffraction peak, with height intensity, was observed for the ZnO film which indicate that the ZnO film have preferential a-axis orientation perpendicular to the crystallographic plans (100). These results can be explained as it was expressed in the literatures [20,23,24,27].…”

Abstract. The transparent conducting ZnO thin films were deposited on glass substrate by ultrasonic spray technique. The optical, electrical and structural properties of the ZnO thin films were studied as a function of the substrate temperatures in the range of 300 to 400 °C. The as deposited film exhibit a hexagonal structure wurtzite and (101) oriented.The value of grain size G = 28 nm is measured of ZnO film at 350 °C. All the films having high transparency in the visible region, the band gap energy decreased from 3.44 to 3.29 eV with increasing the substrate temperatures from 300 to 400 °C, respectively according to the Burstein-Moss effect (blue shift of Eg). The Urbach energy decreased reaching to minimum at 350 °C; indicating to decrease of the defects. The electrical resistivity of the films at 350 °C is 50 Ω.cm. A systematic study on the influence of the substrate temperatures on the optical, electrical and structural properties of ZnO thin films deposited by ultrasonic spray has been reported.

“…In contrast, we can remark ( Table 2) that the lattice strain and the dislocation density of Sb 2 S 3 films decrease from 75 × 10 −4 to 25 × 10 −4 and 7 × 10 14 to 2 × 10 14 m −2 , respectively, with increasing temperature from 250 to 270 • C. The reduction of lattice strain and dislocation density fits well the enhancement of crystallinity [24] and the decrease of the defects in the films.…”

“…In order to confirm this remark, one can go for the calculation of the texture coefficient TC(h k l). The later can be calculated from the X-ray data using the well-known formula of the intensity peaks corresponding to the (1 0 0), (0 0 2), (1 0 1) and (1 0 2) planes [5]:…”

“…ZnO thin films can be produced by several techniques such as reactive evaporation, molecular beam epitaxy (MBE), magnetron sputtering technique, pulsed laser deposition (PLD), sol-gel technique, chemical vapour deposition, electrochemical deposition [5][6][7] and spray pyrolysis [8]. Among those techniques that have been reported to prepare thin films of ZnO, we will focus more particularly in this paper on the spray ultrasonic technique which is a low cost and suitable method for large-scale production.…”
