Structural and Magneto-Optical Properties of Co-doped ZnO Thin Films Prepared by Sol-Gel Method

Neamtu J., Teodorescu C., Georgescu G., Ferré J., Malaeru T., Jitaru I., National Institute for Research&Development in Electrical Engineering, RO

Co doped ZnO thin film has promising potential for spintronic devices. Theoretical calculations predict ferromagnetism for Diluted Magnetic Semiconductors (DMS): ZnO doped with transition metals (Fe,Co,Ni). We have investigated Co (x=0.05-0.30) doped ZnO (Zn1-xCoxO), films [...]

Total flexibility in thin film design using polymer nanocomposites

Druffel T., Buazza O., Lattis M., Farmer S., Optical Dynamics, US

Optically clear, mechanically flexible nanocomposites are created by doping host polymers with nanoparticles having higher or lower refractive indices. The composite materials preserve the viscoelastic properties of the binding polymers and exhibit infinite tunability between [...]

Dispersion and incorporation of optical nanotracers

Samuel J., Raccurt O., Poncelet O., Tillement O., Tardif F., Commissariat à l’Energie Atomique, FR

Silica fluorescent nanoparticles of 40nm diameter are synthesized by a reverse microemulsion process. Numerous industrial applications involve the homogeneous incorporation of nanoparticles into a polymer matrix. Nevertheless, because of their low size, nanoparticles tend to [...]

Magnetic nanoparticles with variable size and shape and surface functionality as switchable building blocks for soft nanotechnology

Dietsch H., Malik V., Reufer M., Schurtenberger P., Fribourg Center fro Nanomaterials, FriMat, CH

Alpha-Fe2O3 (hematite) particles can be synthesized by forced hydrolysis of iron salts. The chosen iron salt dissolves and leads to a first crystalline structure called akaganeite (Beta-FeOOH), which, reorganized and combined with more iron precursor [...]

Nanoscale Deformation Measurements – Concepts for Failure and Reliability Assessment at the Nanoscale

Michel B., Gollhardt A., Keller J., Fraunhofer Institute for Reliability and Microintegration, DE

The paper presents two methods for deformation measurement at the nanoscale level. The first method is based on Scanning Probe Microscopy (SPM) in combination with Digital Image Correlation (DIC). The technique serves as the basis [...]

Thermal Cycling of 300 nm Buried Damascene Copper Interconnect Lines by Joule Heating

Read D.T., Geiss R.H., National Institute of Standards and Technology, US

We report tests of 300 nm wide damascene copper interconnect lines in silicon oxide dielectric to failure under high amplitude, low frequency alternating current. The cyclic minimum and maximum resistances were obtained from the measured [...]

Metallic submicron wires and nanolawn for microelectronic packaging. Concept and first evaluation

Fiedler S., Zwanzig M., Schmidt R., Scheel W., Fraunhofer Institut Zuverlässigkeit und Mikrointegration (IZM), Berlin, DE

Starting with a brief review of submicron wire production techniques, promising applications of submicron and nano wires are discussed. Observed attractive properties of metal rod decorated metal surfaces, so called nano lawn, for low energy [...]

Residual Stress Measurements of High Spatial Resolution

Vogel D., Luczak F., Michel B., Fraunhofer Institute for Reliability and Microintegration, DE

Residual stresses in semiconductor and MEMS devices superposing functional and environmental loading are one of the crucial reliability issues as they can add significant stress levels leading finally to component damage. Most of routinely used [...]

Synthesis, Reliability and Applications of Nanocrystalline CVD-grown Diamond and MicroDevice Fabrication

Wiora M., Brühne K., Flöter A.C., Gluche P., Fecht H-J., University of Ulm, DE

The correlation between the micro- and nanostructure of a material and its physical and chemical properties is the key issue in materials development. Considerable progress has been achieved recently by the development of new processing [...]

Improvement of Stab Resistant Body Armor Using SiO2 Nanoparticles Dispersed into Silane Coupling Agent through Sonic Cavitation

Lambert V., Mahfuz H., Bordner P., Florida Atlantic University, US

Enhancing a flexible body armor using the Shear Thickening Fluid theory (STF) with use of SiO2 nanoparticles has shown good results regarding the stab resistance. A completely new approach based on investigations demonstrates that silated [...]
