Abstract:

In this study, we demonstrate a rapid and easy method to synthesis α-Fe2O3 nanowires (NWs). The density of the α-Fe2O3 NWs were successfully control by different thickness of Fe thin film within 10 hours by thermal oxidation at 350 oC in the oven. Iron films with different thicknesses (50 nm and 150 nm) were coated on the indium tin oxide (ITO) glass by direct current (DC) sputtering.The amount of α-Fe2O3 NWs increased with the increase of the film thickness.The photocurrents of the α-Fe2O3 NWs were investigated with the illumination of the simulation solar power.The higher density of the NWs, the photocurrent was higher with the same bias.In this study, we demonstrate a rapid and easy method to synthesis α-Fe2O3 NWs and measure the photocurrent.
