This work, for the first time, examines the work function fluctuation (WKF) and interface trap fluctuation (ITF) using experimentally calibrated 3D device simulation on high-κ/metal gate technology. The random WKs result in 36.7 mV threshold voltage fluctuation (σVth) for 16 nm N-MOSFETs with TiN gate, which is rather different from the result of averaged WKF (AWKF) method [1] due to localized random...
In this study, a hydrothermal route is advanced for the formation of titanium dioxide nanostructures. The wetting properties and structure evolution of the hydrothermally grown TiO2 nanostructures are studied. Sputtered titanium thin films have been treated under hydrothermal conditions. The results show that the morphologies, microstructures and surface properties of the TiO2 nanostructured films...
The work-function fluctuation (WKF) induced threshold voltage variability (σVth) in 16-nm-gate bulk FinFET devices is for the first time explored and modeled by an experimentally validated Monte Carlo simulation approach. A comprehensive analysis of variability sources of FinFETs is first conducted to show the significance of WKF in reliability of nano-device. Then, the influences of grain size of...
The adsorption and photodecomposition of diphenolic acid (DPA) was investigated in the presence of alpha- or beta- cyclodextrins (CDs) and TiO2 suspensions. The adsorption of DPA on TiO2 surface and inclusion complex of CDs and DPA were critical factor in the photocatalytic reaction. Results showed that, the adsorption isotherms of DPA could be plotted with the Langmuir isotherm model, and the maximum...
This paper investigated the photochemical behavior of diphenolic acid (DPA) in the presence of beta-cyclodextrin (CD) and TiO2 suspensions under a 250 W metal halide lamp (lambdages 365 nm). The interaction of DPA with CD yielded the formation of inclusion complexes at 1:1 stoichiometric ratio in solution. The irradiation of DPA and TiO2 suspensions in the presence of beta-CD showed that the photodegradation...
