Abstract: The present invention discloses a metal oxide (MO) semiconductor, which is obtained by doping a small amount of rare-earth oxide (RO) as a photo-induced carrier transportion center into an indium-containing MO semiconductor to form a (In2O3)x(MO)y(RO)z semiconductor material. According to the present invention, a charge transportion center can be formed by utilizing the characteristics that the radius of rare-earth ions is equal to that of indium ions, and 4f orbitals in the rare-earth ions and 5s orbitals of the indium ions, so as to improve the stability under illumination. The present invention further provides a thin-film transistor based on the MO semiconductor and application thereof.
