Layer-by-Layer Self-Assembly of Zinc Oxide/Graphene Oxide Hybrid Toward Ultrasensitive Humidity Sensing

  title={Layer-by-Layer Self-Assembly of Zinc Oxide/Graphene Oxide Hybrid Toward Ultrasensitive Humidity Sensing},
  author={Dongzhi Zhang and Jingjing Liu and Bokai Xia},
  journal={IEEE Electron Device Letters},
A layer-by-layer self-assembled zinc oxide (ZnO)/graphene oxide (GO) film device for ultrahigh humidity sensing was demonstrated in this letter. The morphological and compositional properties of as-prepared ZnO/GO hybrid were characterized by SEM and X-ray diffraction (XRD). The sensing performance of the ZnO/GO hybrid film device toward humidity was investigated, and an unprecedented response was yielded, which surpasses the existing conventional humidity devices. Moreover, this device… CONTINUE READING
