Au nanoelectrodes for breath analysis

Righettoni M., Tricoli A., Pratsinis S.E., ETH Zürich, CH

New medical diagnostic methods such as non-invasive human breath analysis bear the potential of drastically reducing medical costs as a greater amount of automatization is possible. SnO2 is one of the most utilized and best [...]

Fabrication of polymer-derived ceramic nanostructures by imprint lithography

Duong B., Gangopadhyay P., Brent J., Seraphin S., Thomas J., University of Central Florida, US

The conventional technique used for manufacturing miniaturized ceramic components is the powder route which typically does not allow the fabrication of feature sizes smaller than 0.1mm. With the availability of pre-ceramic polymers, processed by various [...]

Fabrication and characterization of thin-film transistors based on Peri-xanthenoxanthene (PXX) derivative

Cui Z., Chinese Academy of Sciences, CN

A new organic materials for OTFTs.

Synthesis of SiOx Nanowires at Low Temperatures Using Zn Catalyst

Choi C-S, Yoon J-H, Kangwon National University, KR

we report that the SiOx NWs can be synthesized by directly exposing Zn film to atomic oxygen and silicon plasma mixture produced by PECVD method using a mixture of SiH4 and N2O gas at temperatures [...]

AuxAg1-x alloy seeds: A way to control growth, morphology and defect formation in Ge nanowiress

Biswas S., Holmes J.D., University College Cork, IE

Ge nanowires are of current interest for high speed nanoelectronic devices due to the lower band gap and high carrier mobility and larger excitonic Bohr radius of Ge yields a more pronounced quantum confinement effect.Most [...]

Hysteresis-free spin valves for GMR sensors

Ustinov V.V., Milyaev M.A., Naumova L.I., Proglyado V.V., Krinitsina T.P., Institute of Metal Physics, RU

Top spin valves Ta/[FeNi/CoFe]/Cu/ CoFe/AFM/Ta based on antiferromagnetics (AFM) Fe50Mn50 and Mn75Ir25 with varying [Fe20Ni80/Co90Fe10] composite free layer parameters and Cu interlayer thickness were prepared by DC magnetron sputtering. GMR characteristics of spin valves (SV) [...]

Exchange Bias Formation Mechanism in (110)Al2O3/Py/Mn/Ta Nanostructures

Blinov I.V., Krinitsina T.P., Matveev S.A., Milyaev M.A., Popov V.V., Ustinov V.V., Institute of Metal Physics, RU

Magnetic multilayer nanostructures possessing exchange bias are of interest for spintronics as effective magnetic field sensors. The mechanism and conditions of the exchange bias formation in (110) Al2O3/Py(30nm)/Mn(100nm)/ Ta(10nm) nanostructures at thermal-magnetic treatment have been [...]

Highly Flexible Transparent Thin Film Heaters based on Metallic Nanowires

Simonato J-P, CEA, FR

We demonstrate that flexible transparent film heaters (TFHs) with excellent performances can be fabricated from solution-processible metallic nanowire thin films. The TFHs were first deposited on glass and heating performances were monitored at different applied [...]

Analysis of GaN Grown on Vertically Standing Fractal-Like Si Nanostructures

Wee Q.X., Soh C.B., Zang K.Y., Chua S.J., Thompson C.V., National University of Singapore (NUS), SG

We have investigated the microstructure and optical properties of GaN grown on vertically standing Si nanostructures by MOCVD. The Si nanostructures array is formed by a simple metal-assisted etching of Si(111) substrates, where both metal [...]
