Abstract

Single-crystalline IGZO (Indium-Gallium-Zinc oxide) was fabricated on c-sapphire substrate. Single crystal ZnO was used as a buffer layer, and post-annealing was treated in $900^{\circ}C$ for crystallization of IGZO. Crystallized IGZO formed superlattice structure spontaneously induced to c-axis direction by ZnO butTer layer, the composition of IGZO was varied by amount of ZnO. Crystallinity and composition of IGZO was analyzed by X-ray Diffraction and Transmission Electron Microscopy.
