This paper reports an enhanced photocatalysis system for organic pollutants degradation, using high-aspect-ratio (HAR) Si/ITO/WO3 micropost photoelectrodes, fabricated by deep reactive ion etching (DRIE) and sputtering. Compared with traditional Titanium Dioxide (TiO2) photoelectrodes, Tungsten trioxide (WO3) coupled with Si can absorb visible light. Besides, an optimized HAR electrode configuration...
Different from conventional unipolar type 1D1R RRAM devices, in this paper, a bipolar type 1D1R RRAM device structure is firstly proposed and successfully demonstrated by the combined TiOx-based Schottky diode and Cu/HfO2/Pt bipolar RRAM cell. Reliable and uniform self-compliance resistive switching characteristics are obtained by imposing current compliance using the reverse bias current of the TiO...
Scaling is a key issue for resistive switching (RS) memory before commercialization. In this paper, for the first time, we reveal the impact of electrode diffusion on the device performance as the thickness of RS material scaling. Serious deterioration of on/off ratio and device yield was observed when the material scaled below 3 nm. A new method of two-step electrode deposition accompanied with re-oxidization...
Graphene, the basic building block of all graphitic materials has received significant scientific interest due to its ultra-high surface area (>2,630 m2/g), high charge carrier mobility, high thermal conductivity, etc. In particular, graphenes high surface area and excellent electrical conductivity has made it a leading candidate for next generation electrode material in energy storage devices...
