摘要

Series of iron oxide thin films with different morphologies are prepared via a facile block copolymer templated wet chemical method and the large area homogeneity of all prepared films are characterized with GISAXS and GIWAXS technique. Compared with the quasi-isoporous nanostructure, improved photoelectric property is obtained when double layered α-Fe2O3 thin film is used as the electron transport modification layer.
