Synthesis and Characterization of Spiral Carbon Nanofibers Containing Pd Metal Cluster by using Pd2(dba)3 as Catalyst

Su C-J, Hsu L-S, Wu T-W., Liu C-J, Lin S-H, Chung Shan Medical University, TW

The spiral carbon nanofibers consisting of Pd metal cluster were grown by the Pd2(dba)3-catalyzed decomposition of gaseous acetylene on molecular sieves (Linde 13X) support. The microstructure and composition of the spiral carbon nanofibers were characterized [...]

Modeling Nanosized Colloidal Particle Interactions with Brownian Dynamics Using Discrete Element Method

Li J-F, Yu W-H, Chen C-S, J. Wei W-C, National Taiwan University, TW

Discrete element method (DEM) has been developed in an integrated software system to study ceramic particle suspension and colloidal forming process recently [1, 2, 3]. Particle interactions such as van der Waals attraction, electrical double-layer [...]

Heat Transfer Macromodels for MEMS Devices with 3D Geometries

Yu C-C, Yang Y-J, National Taiwan University, TW

There are numerous heat transfer applications in MEMS, such as thermal actuating, uncooled infrared sensing, chip cooling, temperature sensing, PCR, and so on. Most of the applications need feedback loops for precise control or actuation, [...]

A Computational Investigation of Electron Energy States for Vertically Coupled Semiconductor Quantum Dots

Li Y., Lu H-M., National Nano Device Laboratories and National Chiao Tung University, TW

We study the induced property of ground and excited state energies of electrons confined in 3D nanostructures that the In_xGa_1-xAs QDs are embedded into GaAs matrix and have a vertically coupled topology. The disk-(DI) and [...]

A Methodology of Field-Emission Modeling with Space-Charge Effects

Tsai T-H, Tang H-K, Yang Y-J, National Taiwan University, TW

In this paper, we present a methodology for modeling and simulating 3D field-emission devices (FED) with space-charge effect. This approach applies a boundary-element-method (BEM) electrostatics solver [1] and an adaptive explicit integrator. The space charge [...]
