Embossed and Intaglio Nano-Patterning using Nanopipette based on the QTF-AFM System
We demonstrated embossed and intaglio nano-patterning using Nanopipette based on the QTF-AFM (Quartz Tunning Fork-Atomic Force Microscopy) system. Used materials in the patterning system were nanoparticles solution and acetone for delivery solution mica and flat [...]
Integrated phase-Change memory in Bi2Te3 nanowires
Han N.A., Kim S.I., Yang J.D., Lee K., Sohn H., So H-M, Sohn H., Ahn C.W., Yoo K.H., Yonsei University, KR
Bismuth telluride (Bi2Te3) and its alloys are considered to be the best avaiable materials for near room-temperature thermoelectric applications. Moreover, because low-dimensional thermoelectric materials are expected to have a higher figure of merit due to [...]
Self-assembled monolayer (SAMs) and electroplating process for Cu filling on 32-nm trench
To improve the conformality of Cu seed layer prepared by ELD, we have also developed a novel activation technique by combining a self assembled monolayer (SAM) and Au catalyst. A coupling agent to anchor Au [...]
Characteristics of co-doped device with hole and electron transport material
We demonstrated green organic lighte-emittin diodes (OLEDs) improved by co-doped using hole transport material, N′-bis-(1-naphyl)-N,N′-diphenyl-1,1′-biphenyl-4,4′-diamine (NPB) and electron transport material, bis(2-methyl-8-quninolinato)-4-phenylphenolate aluminum (Balq), into emitting layer. The co-doped materials impove charge blance by injecting hole [...]
Effect of Thickness based on self-assembly of block copolymer
Block copolymers have been investigated for fabricating functional nanomaterials due to their properties of self-assembly. We prepared polystyrene-b-poly(2-vinyl pyridine) (PS-b-P2VP) lamellar films which is hydrophobic block-hydrophilic polyelectrolyte block polymer have 57 kg/mol-b-57 kg/mol. The lamellar [...]
Microstructures and electrochemical properties of Si-Ni based alloys
In this work, Si-Ni-Al and Si-Ni-Cu-Al alloy ribbons were fabricated by a rapid solidification process to minimize the effect of the volume change of silicon particles. Thin ribbons with thicknesses of 10~20μm were fabricated by [...]
Microstructures and Electrochemical Properties of Rapidly-solidified Si-Mn-Cr alloys
In this work, the microstructure and electrochemical properties of Si-Mn-Cr alloy specimens prepared by a rapid solidification process and a conventionally-solidified process have been investigated. Si70Mn15Cr15 alloy ribbons by atomic ratio were prepared by two [...]
