Abstract: Amorphous transparent conducting oxides (a-TCOs) with potential important optoelectronic applications have attracted extensive attention. However, the achievement of highly conductive and transparent a-TCOs has been challenging. The working hypothesis proposed by Hosono and co-workers suggests that the elements with electronic configuration (n-1)d10ns0 (n = 4) are potential candidates in forming a-TCOs. In this study, appropriate elements Ag, Ge, Al and Y are identified and selected incorporating into indium zinc oxide (IZO) for achieving highly conductive and transparent a-IZO based TCOs and evaluating the working hypothesis. Different amount of each foreign element is incorporated into a-IZO though co-sputtering, and the electronic, optical and structural properties are investigated using various technologies. Highly conductive and transparent amorphous TCOs are achieved through a systematic study, and some new phenomena are found and a deeper understanding of amorphous TCOs is achieved.
