Abstract

We used a solution process to fabricate transparent nanocrystalline (nc) InGaO 3(ZnO) 2 thin films on a glass substrate. The formation of the nanocrystals resulted from a self-solid phase reaction (S-SPR). The nanocrystals began to form at a temperature of ̃300 °C, and grew gradually with increasing postannealing temperatures. The optical transmittance of the nc-InGaO 3(ZnO) 2 thin film was ̃92% in the visible range. Fewer oxygen deficiencies occurred in the InGaO 3(ZnO) 2 thin film that was transited from the amorphous (a) to the nc phase. The ratio of oxygen to indium, gallium, and zinc was 1.16, which is close to the stoichiometric value for the nc-InGaO 3(ZnO) 2 thin film.
