      Zhao, Zhou; Zhang, Zengxing; Jing, Junmin; Gao, Rui; Liao, Zhiwei; Zhang, Wenjun; Liu, Guohua; Wang, Yonghua; Wang, Kaiying; Xue, Chenyang (Peer reviewed; Journal article, 2023)
      As a typical representative of micro/nano-textured silicon, black silicon has excellent light absorption properties and is gradually surfacing as a substitute for standard silicon in photoelectric devices. Black silicon ...
    • Enhanced photoelectric response of plasmon-active ZnO nanorods by spatial modulation of dielectric environment 

      Liu, Guohua; Dao, Nguyen Duy Phuong; Nguyen, Vy; Du, Kang; Cheng, Chaoqun; Xu, Jinliang; Wang, Kaiying (Peer reviewed; Journal article, 2019)
      One-dimensional zinc oxide (ZnO) nanorods have excellent electron mobility and exhibit great potential for photoelectric or photochemical applications. However, poor visible light absorption and rapid surface charge ...
    • Photoactive decontamination and reuse of face masks 

      You, Dingzhang; Liu, Qingyuan; Wang, Lin; Wang, Kaiying; Liu, Guohua (Peer reviewed; Journal article, 2023)
      The corona virus disease 2019 (COVID-19) pandemic has led to global shortages in disposable respirators. Increasing the recycling rate of masks is a direct, low-cost strategy to mitigate COVID-19 transmission. Photoactive ...
    • Synthesis and Applications of Free-standing TiO2 Nanotube Membranes 

      Liu, Guohua (Doctoral theses at Vestfold University College;2, Doctoral thesis, 2013)
      Nanostructured TiO2 nanotubes (TNTs) have great application potential in optoelectronic devices due to large effective light harvesting surface area and wide band gap. Anodization of Ti is a simple way to prepare well-ordered ...
