Abstract :
The oblique-angle sputtering of ZnO thin films doped by Ga (ZnO:Ga) with oblique-angle of 80° to the horizontal (target) plane was performed. It improved significantly their preferred crystalline (002) texture and columnar crystalline structure tilted of about 14° declination from the substrate normal, decreased their electrical resistivity down to value of 4.4 × 10-3 Ωcm and increased optical transparency up to 88 %. in comparison with films deposited perpendicularly to substrate.
