    • Designing an Efficient Multimode Environmental Sensor Based on Graphene-Silicon Heterojunction 

      Shehzad, Khurram; Shi, Tianjin; Qadir, Akeel; Wan, Xia; Guo, Hongwei; Ali, Ayaz; Xuan, Weipeng et al. (Wiley, 2017-04)
      By exploiting the adsorbent gaseous molecules induced changes in intrinsic properties of graphene/silicon (Gr/Si) Schottky junction, the authors report a sensitive, low-power consuming, multimode environmental sensor. By ...
    • Fast Response and High Sensitivity ZnO/glass Surface Acoustic Wave Humidity Sensors Using Graphene Oxide Sensing Layer 

      Xuan, Weipeng; He, Mei; Meng, Nan; He, Xingli; Wang, Wenbo; Chen, Jinkai; Shi, Tianjin et al. (Nature Publishing Group, 2014-11-26)
      We report ZnO/glass surface acoustic wave (SAW) humidity sensors with high sensitivity and fast response using graphene oxide sensing layer. The frequency shift of the sensors is exponentially correlated to the humidity ...
    • Solvent-Based Soft-Patterning of Graphene Lateral Heterostructures for Broadband High-Speed Metal-Semiconductor-Metal Photodetectors 

      Xu, Yang; Ali, Ayaz; Shehzad, Khurram; Meng, Nan; Xu, Mingsheng; Zhang, Yuhan; Wang, Xinran et al. (Wiley, 2017-02)
      Solvents are essential in synthesis, transfer, and device fabrication of 2D materials and their functionalized forms. Controllable tuning of the structure and properties of these materials using common solvents can pave ...
