Plasmon assisted two-photon direct laser writing of micro-structures composed of chiral Ag nanoparticles

Vidal X., Kim W-J, Baev A., S. Jee H., Tokar V., Swihart M.T., The Institute for Lasers, Photonics and Biophotonics, ES

We present an approach to produce micropatterns of metallic nanoparticles (NPs) that preserve key optical properties of the individual NPs. The technique uses a photothermal reaction induced by two-photon direct laser writing. The studied NP [...]

Fabrication and Recording of Bit Patterned Media Prepared by Rotary Stage Electron Beam Lithography

Moneck M.T., Lin W., Powell S., Okada T., Fujimori J., Kasuya T., Katsumura M., Iida T., Kuriyama K., Bain J., Zhu J.-G., Carnegie Mellon University, US

Bit patterned media (BPM) is a promising technology for magnetic recording at ultra-high areal densities beyond 1 Tbit/in2. To be viable, bit patterns must be reliably fabricated across 2.5” disks with few defects and sigma [...]

High spatial resolution Hall nano-sensors by tuned direct-write Co/C-FEBID

Gabureac M.S., Bernau L., Boero G., Utke I., EMPA, CH

Gas assisted focused electron beam induced deposition (FEBID) is a direct write technique that allows for the deposition of nanoscale structures inside standard scanning electron microscopes (SEM). Here we show that composition of the nano-deposits [...]

Polarisation stabilisation of telecom lasers by minimally-invasive direct-write focused electron beam induced deposition

Utke I., Jenke M.G., Roeling C., Thiesen P.H., Iakovlev V., Sirbu A., Mereuta A., Caliman A., Kapon E., EMPA, Swiss Federal Laboratories for Materials Science and Technology, CH

The possibility to deposit or remove very small amounts of material for tuning purposes on a fully processed micro/nanodevice at the right place, at will, and without damage to surrounding sensitive areas can be very [...]

Mechanisms of Photonic Curing™: Processing High Temperature Films on Low Temperature Substrates

Schroder K.A., NCC Nano, LLC, US

Photonic Curing uses flashlamps to thermally process a thin film at high temperature on a low temperature substrate without damaging it. This has utility in printed electronics, where high temperature curing is generally equated to [...]

Picosun SUNALE™ ALD process tools for nanoscale coatings – seamless transition from R&D to industrial production

Toivola M., Soininen P.J., Lehto T., Pilvi T., Picosun Oy, FI

Atomic Layer Deposition (ALD) offers a superior way to coat highly conformal, uniform, pinhole and defect free thin films on even the most challenging nanoscale architectures. The technique has tremendous potential in several fields of [...]

Development of Methanol Based Reactive Ion Etching Processes for Nanoscale Magnetic Devices

Moneck M.T., Zhu J.-G., Carnegie Mellon University, US

Recent advances in the area of magnetoelectronics include the development of bit patterned media (BPM) for hard disk drives and the realization of spin transfer torque (STT) devices. As feature sizes shrink to sub-50 nm [...]

Photonic Sintering of Silver for Roll-to Roll-Printed Electronics

Ahmed S., Xenon Corporation, US

The use of high energy Pulsed Light is presented as a means of sintering printed nano- particle inks to form conductive traces on flexible substrates. These novel metal nanoparticle based inks are ideally suited for [...]

From the fabrication strategy to the device integration of gas nanosensors based on individual nanowires

Jiménez-Diaz R., Prades J.D., Casals O., Andreu T., Morante J.R., Mathur S., Fonseca L., Santander J., Barth S., Hernandez-Ramirez F., Romano-Rodriguez A., Universitat de Barcelona (UB), ES

In the last years, nanowires have emerged as potential building blocks of new devices and circuit architectures due to their performance derived from their reduced size and well-controlled chemical and physical properties [1]. Large efforts [...]

Application of focused ion beam technology for photonic nanostructures

Ay F., Gadgil V.J., Geskus D., Aravazhi S., Wörhoff K., Pollnau M., MESA+ institute of nanotechnology, University of Twente, NL

Al2O3 and KY(WO4)2 are promising materials for photonic applications with excellent optical properties and of interest for obtaining on chip resonator structures. However, there is no method available to fabricate these structures except FIB technology. [...]
