The modeling of p?InxGa1-xN/n?Si hetero junction diodes without using the buffer layer were investigated with the ?top-top? electrode. The p?Mg-GaN and p?Mg-In0.05Ga0.95N were deposited directly on the n?Si (100) wafer by the RF reactive sputtering at 40...

The hole blocking layer plays an important role in suppressing recombination of holes and electrons between the perovskite layer and fluorine-doped tin oxide (FTO). Morphological defects, such as cracks, at the compact TiO2 hole blocking layer due to rou...

Film cooling enhancement by incorporating an upstream sand-dune-shaped ramp (SDSR) to the film hole exit was numerically investigated on a flat plate under typical blowing ratios ranging from 0.5 to 1.5. Three heights of SDSRs were designed: 0.25D, 0.5D,...

The photocatalytic activity and stability of thin, polycrystalline ZnO films was studied. The oxidative degradation of organic compounds at the ZnO surface results from the ultraviolet (UV) photo-induced creation of highly oxidizing holes and reducing el...
