The physical properties of amorphous indium zinc oxynitride (a-IZON) thin films, which were deposited at room temperature by reactive RF magnetron sputtering, were investigated. The results of the investigations indicated that the a-IZON films possessed excellent qualities: high transparency with a very low resistivity from ${10}^{-3}$ $\Omega \cdot$cm to ${10}^{-4}$ $\Omega \cdot$cm, while the carrier concentration showed values over ${10}^{20}$ cm ${}^{-3}$ with mobility between $10$ and 21 cm ${}^2\cdot$V ${}^{-1}\cdot$s${}^{-1}$. The incorporated nitrogen reduces the typical crystallization of IZO and favors the deposition of transparent thin films. These results show that the IZON is an ideal amorphous material for applications in transparent and flexible optoelectronic devices.
