Synthesis of silicon nanoparticles by picosecond laser ablation in liquid

Popovic D.M., University of Belgrade-Faculty of Physics, RS

The one of the most promising method for the producing of silicon-based NPs is the laser ablation of solid target in liquid (LAL), because it’s relatively simple, fast and “green”. In this work we produced [...]

Standards of length at the nanoscale based on movement gages and their measurement with sub-nanometric uncertainty

Luskinovich P.N., Zhabotinsky V.A., Lubashevsky I.A., NANOMETER Standard GmbH, DE

The manufacture of nano-electronic devices, nano manipulators, and microelectromechanical sensors, as well as elaborations of nano-technological processes with atomic spatial resolution have made it necessary to calibrate measuring devices at the nanoscale with sub-nanometric error. [...]

Mechanical fabrication of graphene devices using focused-ion beam: deposition and milling

Lei N., Chen Z., Kim D., Xue W., Xu J., Xue W., Washington State University, US

The inherent difficulties in handling and producing graphene have been a major barrier in developing such devices. Conventional microfabrication methods are mostly based on chemical etching processes, which often involve tedious masking and aligning steps. [...]

Multiple surfaces pretreatments of nanoporous SiO2-based dielectric layers for electroless plating of copper

Chen G.S., Feng Chia University, TW

In this work, Black Diamond II (DB II with a chemical formula of SiOC:H), a leading nanoporous chemically vapor deposited dielectric layer, is examined as a test case for the SiO2-derived nanoporous IMDs, demonstrating the [...]

Investigation of Metal Nano Layer Formation by the Tunneling Current through the Thin Oxide Film in the Electrolyte–Oxide–Silicon System

Lee S-H., Cheon J-H, Choi S., Choi Y., Choi S., Choi Y., Park Y.J., Seoul National University, KR

In the researches on Electrolyte–Oxide–Silicon (EOS) system, tunneling current through the gate insulator has been considered as an undesirable factor causing reliability issues such as gate insulator degradation and interface state generation. In this work, [...]

Fabrication of controlled linear assemblies of graphite nanosheets in polysiloxane-based nanocomposite films and enhancement of thermal property

Cho H.-B., Yanahara S., Nakayama T., Suematsu H., Suzuki T., Jiang W., Tanaka S., Niihara K., Nagaoka University of Technology, JP

In the present research, we report successful control of orientation and relocation of GNs in polymer matrix using electric and magnetic fields inducing external torques. According to modulation of the external torque, GNs can establish [...]

A nanoscale machine shop for NWs

Cheng G.J., Li Ji, Purdue University, US

One-dimensional nanomaterials have attracted a great deal of research interest in the past few decades due to their unique mechanical, electrical and optical properties. Changing the shape of nanowires (NWs) is both challenging and crucial [...]

All polymer, injection molded nanoslits, fabricated through two-level UV-LIGA processes

Østergaard P.F., Mateucci M., Marie R., Kristensen A., Taboryski R., Technical University of Denmark, DK

Micro- and nanofluidic systems fabricated in silicon and glass substrates are expensive and have long production cycles. To minimize the time used by researchers to fabricate their systems, rather than using them, medium to high [...]

Directed Self Assembly: a Novel, High Speed Method of Nanocoating Ultra-thin Films and Monolayers of Particles

Powch G.A., Jain A.R., VersuFLEX Technologies LLC, US

A novel, practical fluidic method is presented for coating ultra-thin, ultra-uniform layers and realizing self-assembled monolayers of particles, into nanoscale in atmosphere and room temperature at rates scalable to web processes at >4 m/min. A [...]

A Pressure Controlled Pinched Flow Fractionation Device for Continuous Particle Separation

Trosborg J., Christiansen T.L., Technical University of Denmark, DK

A demonstration of a pinched flow fractionation device that enables pressure controlled tuning of the separation range of particles. This makes the device ready for easy and cheap mass-production, maintaining great flexibility, and rendering the [...]
