High-Frequency Characteristic Optimization of Heterojunction Bipolar Transistors

Li Y., Hwang C-H, Chen Y-C, National Chiao Tung University, TW

In this paper, an optimization technique (so-called the geometric programming) is employed to optimize the base doping and Ge-dose for SiGe HBTs with high cut-off frequency and base-collector current gain. This work first formulates Kroemer’s [...]

Nanoparticle-enhanced Magnetic Field Induces Apoptosis in Nematode

Huang G.S., Yeh L.K., Chen Y-C, National Chiao Tung University, TW

To investigate molecular consequence of magnetic field to C. elegans, Fe3O4 nanoparticles were incorporated into the culture media of C. elegans and the nematodes were grown under magnetic field for 4 days. For the expermental [...]

Nanoimprint Mold Manufacturing with Focused Ion Beam

Chung M., Huang B.R., Weng M.H., Fu C.S., Chang Y.Y., Lai S.W., Chiou J.M., Chen Y-C, Tzeng Y.H., Southern Taiwan University of Technology, TW

Nanoimprint lithography (NIL) is an emerging low cost technique for reproducing sub-100 nm pattern in various applications; however, manufacturing the mold for nanoimprint has been a key issue both in expense and resolution. Focused Ion [...]

Application of Quantum dots for the lifespan study of Caenorhabditis elegans

Huang G.S., Chang K-M, Chen Y-C, Yeh L-G, National Chiao Tung University, TW

The progress in identifying drugs that extend lifespan of Caenorhabditis elegans has been slow partly due to the tedious and labor-intensive nature of drug screening. We labeled C. elegans by mixing quantum dots, FITC, or [...]
