Abstract :
This paper presents a heavily doped semiconductor indium-tin-oxide (ITO) as the two dimensional electron gas (2DEG). Samples fabricated by electron beam evaporation consists of a structure of glass substrate/30 nm ITO/30 nm CoFe/15 nm ITO/50 nm CoFe. In addition, a two layer structure ITO/CoFe is designed for the test of the I-V relationship of the ITO/CoFe junction. The spin transport through ohmic contact from CoFe into ITO is proved confidently to be true.
