In this paper, we demonstrate successful growth of single spinel phase In_0.22Zn_0.55Sn_0.23O_1.34 films at 300 °C using meticulous cation composition design and catalytic chemical reaction. The devices exhibit an exceptional field-effect mobility of 83.2 cm²/Vs, along with outstanding reliability under external gate bias stress and excellent uniformity.
