Electronic Structure and Band Gap Engineering of ZnO-based Semiconductor Alloy Films

Liu P-L, Shao P-T, National Chung Hsing University, TW

We conduct first-principles total-energy density functional calculations to study the band structures and atomic structures in ZnO and Zn0.5M0.5O alloys using the planewave projector augmented-wave (PAW) method with the Heyd-Scuseria-Ernzerhof (HSE) hybrid functional. We find [...]

Simulation of a High Compliant Micro Electromagnetic Generator for Energy Harvesting

Wu G-Y, Chen S.J., National Central University, TW

A micro electromagnetic generator for vibration energy harvesting is modeled and simulated. This prototyping electromagnetic generator converts change of magnetic flux to induced electromotive force (EMF) from environmental vibration energy. The mechanical FEA was conducted [...]

Li Y., Su H-W, Chen C-Y, Chen Y-Y, Cheng H-W, Cheng H-W, Chen C-Y, Chen Y-Y, Cheng H-W, Chang H-T, National Chiao Tung University, TW

Abstract – In this work, we statistically study characteristic fluctuation of 16-nm-gate high-/metal gate (HKMG) MOSFETs by random-discrete-dopants (RDDs) inside silicon channel and random-interface-traps (RITs) at high-k/silicon interface. Randomly generated devices with three-dimensional (3D) RDDs [...]

Tunable-Linewidth Nanoimprint Working Stamps Fabricated by Double Oblique Metal Deposition

Lin C.H., Wu C-L, Sung C.K., National Tsing Hua University, TW

This paper proposes a low cost but rapid methodology for fabricating working stamps with tunable line-width or pitch structures. Conventionally, the master stamp for nanoimprint lithograph (NIL) is made of silicon by e-beam lithography, which [...]

Multiple surfaces pretreatments of nanoporous SiO2-based dielectric layers for electroless plating of copper

Chen G.S., Feng Chia University, TW

In this work, Black Diamond II (DB II with a chemical formula of SiOC:H), a leading nanoporous chemically vapor deposited dielectric layer, is examined as a test case for the SiO2-derived nanoporous IMDs, demonstrating the [...]

Motion of Magnetic Chains in a Vibrating Field

Li Y-H, Sheu S-T, Pai J-M, Chen C-Y, National Chiao Tung University, TW

In this work, we have carried out an intensive experimental study on the manipulations of micro magnetic particle chains under vibrating magnetic fields. The chain is firstly formed by a uniform directional field, and then [...]

Photocurable Composite with Antimicrobial Activity for Wound-Healing

Chang M-H, Ding F.-C., Ju W.-Y., Lai P.S., National Chung Hsing University, TW

To develop an appropriate approach that can accelerate the wound healing rate or prevent other microorganisms contamination is necessary for wound healing. In this study, the combination of antimicrobial activity and photodynamic antimicrobial chemotherapy of [...]

In situ monitoring of temperature and voltage in lithium-ion rechargeable batteries using flexible micro two-in-one sensors

Lee C.-Y., Lee S.J., Lee C.-Y., Lee S.J., Tang M-S, Chen P-C, Chang Y-M, Yuan Ze University, TW

Under overcharge conditions, the interior temperature of polymer lithium-ion rechargeable batteries will rapidly increase. Such batteries are adopted in electric vehicles that require rapid charging and discharging, and this process causes rapid heating, raising safety [...]

Random Work Function Induced DC Characteristic Fluctuation in 16-nm High-k/Metal Gate Bulk and SOI FinFETs

Su H-W, Chen C-Y, Chen Y-Y, Cheng H-W, Chen C-Y, Chen Y-Y, Cheng H-W, Cheng H-W, Chang H-T, Li Yiming, National Chiao Tung University, TW

This work studies the metal gate’s work function fluctuation induced DC characteristic fluctuation in the 16-nm bulk and silicon-on-insulator (SOI) fin-type field effect transistor (FinFET) devices using an experimentally calibrated 3D device simulation. The method [...]

Chemical Fluid Deposition of Ru/MCM-41 as Catalyst for Hydrogenation in Green Environments

Lin H.W., Yen C.H., Tan C.S., National Tsing Hua University, TW

The Ru/MCM-41 catalyst prepared by chemical fluid deposition technique exhibited high catalytic activity for hydrogenation of p-xylene, bisphenol A, bisphenol F and benzoic acid, which was higher than that of a conventionally prepared Ru/MCM-41 catalyst. [...]
