High conformity sidewall ZnO nanorods are manufactured on etched Si by hydrothermal method. The temperature is fixed at 90 degree Celsius. The morphology of ZnO nanorods is examined by scanning electron microscopy. Also, the results show that we successfully spin coat ZnO seed layer on the sidewalls of grooves. Moreover, ZnO nanorods are grown in grooves of etched Si substrate.
We analyze the polarization-preserving property of two conventional edge-lit light guide plates (LGPs) based on scattering dots and refractive microgrooves and find that these two structures almost completely depolarize the incident linearly polarized light. We then propose a new edge-lit LGP based on total internal reflection (TIR). Simulation results show that such a TIR-based LGP can largely preserve...
High oriented (002) gallium nitride (GaN) thin film is manufactured on 2inch c-plane oriented sapphire by pulsed laser deposition (PLD). The target we used was polycrystalline GaN target. During the growth of GaN, nitrogen gas was purged and the pressure is controlled at 10 mtorr while the temperature and energy are optimized. The surface roughness is measured by atomic force microscopy (AFM) while...
Gallium nitride (002) via pulsed laser deposition (PLD) is manufactured on sapphire substrate and hydrothermal-grown ZnO on sapphire. The film was deposited through the 248nm pulsed laser at 5×10− 3 torr nitrogen atmosphere. Temperature was controlled at 800 °C. The morphology of ZnO buffer layer and GaN films was examined using SEM and the crystallinity of the films was examined by XRD. In contrast...
