Abstract

A double-layer carbon-doped zinc oxide (ZnO/C) film structure was prepared using electrically induced crystallization (EIC) diffusion. The bottom layer atoms (C) were doped into the ZnO crystal structure, inducing intrinsic ferromagnetic characteristics and enhancing optical and electrical properties. The ion implantation process for ZnO/C is discussed in terms of optical, electrical, and magnetic performance. The sensitivity and switching speed of ZnO/C for sensing a volatile gas (alcohol) are evaluated. The EIC process leads to better sensitivity compared to those obtained with annealing and the ion implantation process.
