In this study, we used a citrate reduction method and electrophoretic deposition (EPD) to prepare hybrid nanocrystalline TiO2/Au films and applied on the photoelectrode of dye-sensitized solar cell. The films and solar cells were investigated by field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray analysis (EDX), I-V characteristics, and electrochemical impedance spectroscopy...
This work investigates the characteristics of ZnO film as resistive RAM (RRAM) using Al electrode. Effects of oxygen composition in ZnO film is also studied using different Ar/O2 gas flow ratio. From the electrical characteristics, the resistance ratio (HRS/LRS) can be up to 1010, and the set and reset voltage is lower to 0.5V and 2.5V, respectively.
The evaluation of the high tech Thin Film Transistor-Liquid Crystal Display (TFT-LCD) industry is not easy. Decisions about investing in the latest generation plant involve billions of dollars and a great deal of uncertainty. The traditional company evaluation method Net Present Value (NPV) rule is a `static discount of future cash flow' concept that fails to capture the industry characteristic of...
In this work, we study the effects of rapid thermal annealing (RTA) on HfO2 and HfSiOx gate dielectrics. The film electrical characteristics, TDDB reliability, breakdown characteristics and mechanism, and the optimum temperature of N2 RTA treatment were investigated. We also propose a model to explain breakdown mechanism and the difference between HfO2 and HfSiOx dielectrics. For lifetime projection...
Mesoporus silica dielectrics, which revealed low refractive index (n~1.26), were introduced together with Si3N4 layers to be double-layer-based graded-refractive-index anti- reflectors for silicon solar-cells. Enhanced solar-light transmission increased conversion efficiency of Si solar panels by 4%. The degradation in photovoltaic efficiency of solar panels that were covered with Si3N4/MS anti-reflectors...
