One-dimensional (1D) TiO2 nanowires (NWs) have potential applications in photoelectrochemical (PEC) photodetectors due to their unique 1D geometries and optical electrical properties. However, the wide bandgap insufficient surface area of NWs hinder response spectra responsivity. Constructing mixed-dimensional heterostructures may improve PEC performance by controllably tuning structure properties materials with different dimensionalities. In this strategy, TiO2/ZnO/Ag core–shell were...
In this work, micro Zn-doped Ga2O3 films (GZO) were deposited by one-step mixed atomic layer deposition (ALD) followed post-thermal engineering. The effects of Zn doping and post-annealing temperature on both structure characteristics electric properties investigated in detail. combination plasma-enhanced ALD thermal ZnO can realize the fast growth rate (0.62 nm/supercyc.), high density (4.9 g/cm3), smooth interface (average Rq = 0.51 nm) film. addition, engineering GZO was achieved setting...
Abstract Cuprous oxide (Cu 2 O) thin films were prepared by using electrodeposition technique at different applied potentials (−0.1, −0.3, −0.5, −0.7, and −0.9 V) annealed in vacuum a temperature of 100°C for 1 h. Microstructure optical properties these have been investigated X-ray diffractometer (XRD), field-emission scanning electron microscope (SEM), UV-visible (vis) spectrophotometer, fluorescence spectrophotometer. The morphology varies obviously potentials. Analyses from...
Cu2O-modified ZnO nanorods are prepared by a two-step electrodeposition method on ITO substrates, and the deposition time of Cu2O is 0, 1, 5, 10 min, respectively. particles embedded in interspaces nanorods, amounts increase obviously when lasts longer.
