In2O3 thin films have been deposited on glass substrates by spray pyrolysis using InCl3 as the precursor. The effect of precursor concentration that varied in the range, 0.01-0.25 M on the physical properties of sprayed In2O3 films deposited at 400 oC was investigated. The structural properties of the as-deposited films were studied using X-ray diffractometer and Atomic force microscope. The XRD analysis indicated that the layers had cubic structure with (222)/(400) as the preferred orientation. The AFM studies revealed a decrease of grain size at higher precursor concentrations with an increase of surface roughness. The layers were optically characterized in order to evaluate the absorption coefficient, optical band gap, refractive index, extinction coefficient and other optical parameters. An average visible transmittance of ~ 90 % was observed with an optical band gap of 3.62 eV for the layers grown at a solution concentration of 0.1 M. The Hall effect measurements revealed that the films deposited at a solution concentration, 0.1 M exhibit a minimum resistivity of 2.72x10-3 Ωcm with the carrier concentration and mobility of the order of 7.6x1019 cm-3 and 30.2 cm2/Vs respectively. The layers showed the highest figure of merit of 8.2x10-3 Ω-1.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
