Growth and Characterization of Epitaxial Fe Nanoislands on Si(001): Size Effects on Ferromagnetic Anisotropy
Chuan-Pu Liu

In current magnetic recording media, thin film technology is employed with the size defined by lithography. In order to increase the density and thus decrease the size of each pixel, the optimal object is tiny dots. The direct growth of self-assembled nonodots on a substrate of different kind is called heteroepitaxial growth. A key advantage of using self-assembled nanoparticle arrays in data storage media is …

Involvement of ubiquitin-proteasome system in the D-cycloserine-induced augmentation of fear memory extinction
Po-Wu Gean

Consistent with previous reports, we found that DCS infused bilaterally into the amygdala before extinction training augmented reduction of startle potentiation. Unexpectedly, conditioning-induced increase in GluR1 was reversed by DCS in combination with extinction training. By measuring GluR1 internalization using cell-surface biotinylation techniques, the purpose of this study was to elucidate …

Improved Compact Broadband Bandpass Filter Using Branch Stubs Co-Via Structure with wide stopband characteristic
Mau-Phon Houng

Recently, the broadband bandpass filters are particularly promising in the design of broadband filters with compact size and superior stopband performance due to the fast development of broadband wireless communication systems. Because of the rapidly expanding broadband systems, the requirements for filter design have become stricter. Until this date, developing broadband BPFs were made. However, …

Novel cathode structure for organic light-emitting diodes
Tzung-Fang Guo

1. Introduction

Our recent works have shown that an improved “high-yellow” phenyl-substituted poly-(paraphenylenevinylene) copolymer (HY-PPV) based polymer light emitting diode can be constructed by using an insulated polymer between the metal cathode and light emissive layer. [Ref.1] The turn-on voltage for the insulated polymer incorporated device is markedly reduced. Furthermore, the EL intensity is …
