Effect of Thickness based on self-assembly of block copolymer

Lee S-W., Park N.R., Kim S.Y., Shin D.M., HongKong University, KR

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 [...]

Vertically aligned carbon nanowires (CNWs): Top-down approach using photolithography and pyrolysis

Lee J.A., Lee S-W., Lee S.S., Lee J.A., Lee S-W., Lee S.S., Lee J.A., Lee S-W., Lee S.S., Korea Advanced Institute of Science and Technology (KAIST), KR

Top-down approach for vertically aligned CNWs has not reported yet although it is necessary for immediate integration of CNWs with micro and nano systems. In this paper, vertically aligned pyrolyzed carbon nanowires (CNWs) is fabricated [...]

Anchoring and alignment behavior of liquid crystals on poly(vinyl cinnamate) thin films

Lee S-W., Lee T.J., Hahm S.G., Lee S-W., Lee T.J., Ree M., Pohang University of Science and Technology, KR

At present, a rubbing process using a fabric is the only technique adopted in the LC display industry to treat PI film surfaces for the mass-production of flat-panel LC display devices. However, this process has [...]

Halo Doping: Physical Effects and Compact Modeling

Mudanai S., Rios R., Shih W-K, Packan P., Lee S-W., Intel Corp., US

As the devices are scaled to ultra short channel lengths, pocket or halo implants have been used widely to reduce DIBL and other short channel effects. Although, the use of halo implants helps with control [...]

The effect of electric field on the surface of nanoparticles (TiO2 & SiO2) and its application to retardation of membrane fouling

Park S-E, Park S-J, Ry D-Y, Kwak J-W, Lee S-W., Park S-E, Park S-J, Associate Professor, Kyungwon University, KR

Since electrostatic device has been practiced for anti-foulant treatment effect on processing the industrial wastewater, the electric force is suspected to induce the alteration of surface charges of colloidal particles in the aspect of reducing [...]

Systematic Global Calibration of a Process Simulator

Lee J-H., Lee S-W., Kim K-D., Kim Y-W., Kong J-T., Lee J-H., Lee S-W., Kim K-D., Kim Y-W., Baek D-H., Samsung Electronics Co.Ltd., KR

This paper proposes a novel methodology of systematic global calibration of a process simulator and validates its accuracy and efficiency with application to memory and logic devices. With 175 SIMS profiles which cover the whole [...]
