3C-SiC consists of light elements (Si and C) and its crystal symmetry (zincblende) is the same as that of GaAs. Therefore, it allows a hybridized situation of Si and GaAs. In n-type conduction, these two materials have different spin relaxation mechanisms: the Elliott-Yafet type and the D’yakonov-Perel type. To unveil the spin relaxation physics in n-type 3C-SiC, a spin transport device using spin pumping was fabricated and we obtained a signal indicating spin transport thorough the 3C-SiC channel.
