A novel cyclic forward-backward extrusion process for production of ultrafine grains materials

Alihosseini H., Asle Zaeem M., Dehghani K., Mississippi State Univeristy, US

A new cyclic forward-backward extrusion (CFBE) process was introduced as a severe plastic deformation (SPD) technique to produce ultrafine-grained aluminum rods. According to transmission electron microscopy (TEM) and electron backscatter diffraction (EBSD) results, the average [...]

A study of the Demolding Force in Nano Imprint Lithography For Different Surface Treatments

Moon S.N., Jung J-M, Lee K.M., Lee W.I., Lee K.M., Lee W.I., Seoul National University, KR

The NIL process can be divided into two steps: the pressing and demolding stages. In the pressing stage, micro/nano scale patterns on a mold are transferred to a polymer resist. During this stage, there are [...]

A new method for vertical growth of silicon nanowire in the vapor-liquid-solid (VLS) process

Kim Y.J., Suh D., Lee M.L., Ryu H., Electronics and Telecommunications Research Institute (ETRI), KR

We present a new facile method for vertical growth of the silicon nanowire (Si NW) that obviates the need for SiCl4 in vapor-liquid-solid (VLS) process. The VLS process that involves SiCl4 has two major disadvantages; [...]

Tunable-Linewidth Nanoimprint Working Stamps Fabricated by Double Oblique Metal Deposition

Lin C.H., Wu C-L, Sung C.K., National Tsing Hua University, TW

This paper proposes a low cost but rapid methodology for fabricating working stamps with tunable line-width or pitch structures. Conventionally, the master stamp for nanoimprint lithograph (NIL) is made of silicon by e-beam lithography, which [...]

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 [...]
