Effects of NH Plasma and Mg Doping on InGaZnO pH Sensing Membrane.

In this study, the effects of magnesium (Mg) doping and Ammonia (NH) plasma on the pH sensing capabilities of InGaZnO membranes were investigated. Undoped InGaZnO and Mg-doped pH sensing membranes with NH plasma were examined with multiple material analyses including X-ray diffraction, X-ray photoelectron spectroscopy, secondary ion mass spectroscopy and transmission electron microscope, and pH sensing behaviors of the membrane in electrolyte-insulator-semiconductors. Results indicate that Mg doping and NH plasma treatment could superpositionally enhance crystallization in fine nanostructures, and strengthen chemical bindings.

Morphological, Material, and Optical Properties of ZnO/ZnS/CNTs Nanocomposites on SiO Substrate.

Ultraviolet A light (UV-A, 320-400 nm), which is unblockable by sunscreen, requires careful detection for disease avoidance. In this study, we propose a novel photosensing device capable of detecting UV-A. Cancer-causing UV light can be simultaneously monitored with tiny rapid response sensors for a high carrier transition speed.
