Current Scaling and Electron Heating in a GaN/AlGaN Two-Dimensional Electron System
Kuang Yao Chen,Li-Hung Lin,Chin-An Chang,Chi-Te Liang,N. C. Chen,P. H. Chang,Wen-Jang Shiue,Zhi-Hao Sun 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.50 No.6
A GaN/AlGaN two-dimensional electron system (2DES) has been prepared on a Si substrate, and the electron heating effect in the 2DES has been studied experimentally by using the resistance of the 2DES as a self-thermometer. The relation $T_e$ $\sim$ $I^{1.42}$ was obtained, which is in contrast to $T_e$ $\sim$ $I^{0.5}$ in the spin-split resistivity peaks in a GaAs/AlGaAs 2DES. A possible reason for this is discussed

The Reflection of Bamboo combines traditional materials with interactive technology, analyzing what the characteristics of the old and new materials are, as well as how to apply technology to the integration of these materials. Through this installation, we reconsider the possibility of integrating traditional materials with modern technology. Adopting bamboo as the main material, this installation raises the spirit of traditional techniques in a unique way and employs bamboo’s special tenacity. Viewers can interact with this installation and experience the strength, esthetics and variation in the demonstrated shadow.
Laser brazing molybdenum using two titanium base fillers
Lin, Chia-Chen,Lee, Cheng-Han,Shiue, Ren-Kae,Shy, Hsiou-Jeng Techno-Press 2012 Advances in materials research Vol.1 No.3
Brazing Mo using Ti and Ti-15-3 foils has been investigated in the experiment. For traditional furnace brazing, solidification shrinkage voids cannot be completely removed from the joint even the brazing temperature increased to 2013 K and 160 ${\mu}m$ thick Ti foil applied in brazing. Similar results are observed from the joint using Ti-15-3 filler. In contrast, the quality of laser brazed joint is much better than that of furnace brazed joint. A sound joint is achieved after laser brazing. Tensile strengths of 418 and 373 MPa are obtained from laser brazed joints at the power of 800W and travel speed of 5 mm/s using Ti and Ti-15-3 fillers, respectively. All laser brazed joints are fractured at the brazed zone and cleavage dominated fractures are widely observed from their fractographs. The Ti base fillers show potential in laser brazing Mo substrate.

<P>We describe the synthesis and characterization of bicontinuous cubic poly(3,4-ethylenedioxythiophene) (PEDOT) conducting polymer gels prepared within lyotropic cubic poly(oxyethylene)<SUB>10</SUB> nonylphenol ether (NP-10) templates with <I>Ia</I>3&cmb.macr;<I>d</I> (gyroid, GYR) symmetry. The chemical polymerization of EDOT monomer in the hydrophobic channels of the NP-10 GYR phase was initiated by AgNO<SUB>3</SUB>, a mild oxidant that is activated when exposed to ultraviolet (UV) radiation. The morphology and physical properties of the resulting PEDOT gels were examined as a function of temperature and frequency using optical and electron microscopy, small-angle X-ray scattering (SAXS), dynamic mechanical spectroscopy, and electrochemical impedance spectroscopy (EIS). Microscopy and SAXS results showed that the PEDOT gels remained ordered and stable after the UV-initiated chemical polymerization, confirming the successful templated-synthesis of PEDOT in bicontinuous GYR nanostructures. In comparison to unpolymerized 3,4-ethylenedioxythiophene (EDOT) gel phases, the PEDOT structures had a higher storage modulus, presumably due to the formation of semi-rigid PEDOT-rich nanochannels. Additionally, the storage modulus (<I>G</I>′) for PEDOT gels decreased only modestly with increasing temperature, from ∼1.2 × 10<SUP>5</SUP> Pa (10 °C) to ∼7 × 10<SUP>4</SUP> Pa (40 °C), whereas <I>G</I>′ for the NP-10 and EDOT gels decreased dramatically, from ∼5.0 × 10<SUP>4</SUP> Pa (10 °C) to ∼1.5 × 10<SUP>2</SUP> Pa (40 °C). EIS revealed that the impedance of the PEDOT gels was smaller than the impedance of EDOT gels at both high frequencies (PEDOT ∼10<SUP>2</SUP>Ω and EDOT 2–3 × 10<SUP>4</SUP>Ω at 10<SUP>5</SUP> Hz) and low frequencies (PEDOT 10<SUP>3</SUP>–10<SUP>5</SUP>Ω and EDOT ∼5 × 10<SUP>5</SUP>Ω at 10<SUP>−1</SUP> Hz). These results indicated that PEDOT gels were highly ordered, mechanically stable and electrically conductive, and thus should be of interest for applications for which such properties are important, including low impedance and compliant coatings for biomedical electrodes.</P> <P>Graphic Abstract</P><P>The successful templated-synthesis of PEDOT in bicontinuous GYR nanostructures: highly ordered, mechanically stable and electrically conductive. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c4cp04426f'> </P>
