Abstract: | |
Nanostructured of (PbO) thin films were prepared by spray pyrolysis (CSP) technique at a different substrate temperatures (200, 250, 300, 350, 400, 450) ̊ C . The films deposited were 177 nm thickness. It has been making electrical measurements such as D.C conductivity and, Hall effect for all films. The results showed that the conductivity of (PbO) increasing from [ 75.37 x 10-4 (Ω.cm)-1] to [ 339.99x10-4 (Ω.cm)-1] with increasing of substrate temperatures, as well as the results showed throughout the study that all films have tow activation energy and this energy increase with increasing of substrate temperatures. We noticed from the Hall effect measurements that the films have a negative Hall coefficient. This mean that the type of conducting (n–type charge carriers). |
