Fabrication of 3D carbon microelectrodes for Li-Ion battery applications

Turon Teixidor G., Wang C., Madou M.J., University of California Irvine, US

The fabrication of very high-aspect ratio 3D carbon microelectrodes for Li-Ion batteries is presented. Using a pyrolysis process under inert conditions, thick layers of patterned SU-8 photoresist (up to 700 ?m in height) are converted [...]

Use of Nanocrystalline Ceria in EUV Lithography Optics Polishing

Murray P.G., Böhm T., Maltor H., Nanophase Technologies Corporation, US

EUV lithography promises a huge gain in resolution due to the extremely short wavelength. The necessity of aspherical off-axis mirrors dramatically increased the challenge of manufacture compared to refractive designs. Due to the short wavelength [...]

Low cost PMMA based photo-masks for 3D grey scale micro-structuring applications

Lewis S., Wheeler-Jones R., Perks R., Haynes V., Cardiff university, UK

Grey scale lithography is a useful technique for the fabrication of three dimensional microstructures. Dose dependent positive resist materials are well suited to this application; subsequent dry etching through a suitably patterned etch mask can [...]

Rare Earth-Substituted BI 4Ti3O12 Nanocrystalline Thin Films: Synthesis and Ferroelectric Characterization

Tomar M.S., Katiyar R.S., Perales-Perez O., University of Puerto Rico, Mayaguez Campus, PR

In this work we present the synthesis of bare and rare earth (Ce,Er,Pr)-doped Bi4Ti3O12 (BIT) nanocystalline thin films using a method based on the Sol-Gel process. Thin films were deposited by spin coating on Pt [...]

Electrophotographic Direct-Write for Electronics

Wagner C., Patwardhan R., Jang B., Mahinfalah M., North Dakota State University, US

A new direct-write method based on electrophotography has been developed for use in electronics manufacture. In this research a test bed was created for proof of concept. This test bed was successfully used to print [...]

Novel Design of Molecular Integrated Circuits and Molecular Nanoarchitectronics

Lyshevski S.E., Rochester Institute of Technology, US

This paper reports the results in synthesis and design of novel three-dimensional (3D) nanoscale integrated circuits (nanoICs). These nanoICs can be implemented utilizing multi-terminal molecular devices that exhibit unique electronic characteristics. Aggregated molecules form molecular [...]

Broadcast Photonic Curing of Metallic Nanoparticle Films

Schroder K.A., McCool S.C., Furlan W.R., Nanotechnologies, Inc., US

A novel and industrially scalable technique is presented for curing metal nanoparticle based films in which a large area uncured film is made highly conductive by exposure to a brief, intense pulse of light from [...]

Preparation and Characterization of Nanocrystalline GaP

Pyshkin S.L., Ballato J., Chumanov G., DiMaio J., Saha A.K., Academy of Sciences, Kishinev, Moldova and Clemson University, SC, US

Nanoparticles of GaP have been prepared by the methods of mild aqueous synthesis, gas transport reactions and laser assisted deposition. Transfer of Ga and P by iodine and the next synthesis create onto a substrate [...]

Large scale synthesis of ordered silver nanoparticles for superhydrophobic and anti-icing application

Safaee A., Sarkar D.K., Farzaneh M., Université du Québec à Chicoutimi, CA

Large scale syntheses of ordered colloidal silver nanoparticles have been achieved through solution phase method. These colloidal nanoparticles have been spin-coated on glass substrates and investigated using AFM and UV-Vis spectroscopy. Nearly cubic shape silver [...]

Interpretation of Anomalous Photoluminescence Peak in GaAs1-xNx Grown by Molecular Beam Epitaxy

Fan W.J., Cheah W.K., Yoon S.F., Zhang D.H., Liu R., Wee A.T.S., Nanyang Technological University, SG

Low-temperature (10K) photoluminescence (PL) measurements of GaAs1-xNx epitaxial layers grown on GaAs by solid-source molecular beam epitaxy (SSMBE) reveal an anomalous second peak. Rapid thermal annealing (RTA) of a specific GaAsN sample reveals a lower [...]
