-quality n-type ZnO films as transparent conductive layer, electron injection layer and can improve the light extraction efficiency of the anti-reflective layer. ALD thin film deposition for advanced nano technology to form an atomic-level precision control of film thickness and composition, also has high uniformity and low defect density, large area production batches, and the advantages of sedimentary and low temperature .
Electron microscopy pictures clearly show a diameter of about 24 nm of
