The MgB 2 films have been prepared on the c-cut sapphire substrates by ultrasonic spray pyrolysis (USP) technique using Boric acid and Magnesium acetate tetrahydrate dissolved into distillated water and ethanol as starting materials. The overall concentrations were fixed at 0.1mol/L. During the deposition, 96% Ar - 4% H 2 was used as carrier gas. The reaction temperatures were 850 °C, 900 °C and 950 °C . The deposited MgB 2 films showed strongly (1 0 1) plane orientation. In the sample deposited at 950 °C for 5min, MgB 2 film showed a homogeneous surface, with good grain connectivity. The critical temperature (Tc) was observed to be 31.5 K. The crystal structural and microstructural properties of the MgB 2 films prepared by USP were observed to be strongly dependent on the reacting temperature.

Stage Synthesis

The features of a two-stage synthesis of structured microsystems based on zinc oxide nanorods using ultrasonic spray pyrolysis and a low-temperature hydrothermal method with suppression of nucleation in the bulk of the solution are presented. It is shown that the use of two-stage synthesis provides control over the size and aspect ratio of nanorods. It is proposed to control the concentration of intrinsic surface defects by measuring the photocurrent with irradiation through narrow-band interference light filters.
