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 ... -
Plasmon-induced visible light absorption arising from edge-interfaces of titanium-oxides nanocomposites
Cheng, Chaoqun; Gustavsen, Kim Robert; Wang, Kaiying (Peer reviewed; Journal article, 2021)The efficient utilization of visible light on wide-bandgap metal-oxides is a long-term goal but is still a grand challenge for plasmon-driven chemistry. The plasmon-induced concentration of photons in adjacent materials ... -
Solar-driven plasmonic heterostructure Ti/TiO2−x with gradient doping for sustainable plasmon-enhanced catalysis
Cheng, Chaoqun; Akram, Muhammad Nadeem; Nilsen, Ola; Pryds, Nini; Wang, Kaiying (Journal article; Peer reviewed, 2020)Plasmon-enhanced harvesting of photons has contributed to the photochemical conversion and storage of solar energy. However, high dependence on noble metals and weak coupling in heterostructures constrain the progress ... -
Visible light responsive titanium-oxides for enhanced photoelectrochemical water splitting application
Cheng, Chaoqun (Doctoral dissertations at the University of South-Eastern Norway;134, Doctoral thesis, 2022)Semiconductor-based photoelectrochemical (PEC) water splitting under sunlight has the potential to produce sustainable hydrogen at a low cost and on a large scale. Titanium dioxide (TiO2) is extensively studied as one of ...
