Intrinsic Effects of Materials on Superhydrophobicity of Polymer Replicas from Nature
The present work suggests a mass-producible and large scale fabrication method of superhydrophobic polymeric surfaces by means of material processing equipments which can maximize productivity and cost effectiveness. We fabricated two types of polymeric lotus [...]
Fabrication of electrochemical bio-sensors for the detection of glucose and hydrazine using ZnO nanonails grown by the thermal evaporation process
Umar A., Kim J.H., Kim S-H, Kim J.H., Kim S-H, Park Y.K., Hahn Y.B., Chonbuk National University, KR
Well-crystallized zinc oxide nanonails have been synthesized in a large quantity via a thermal evaporation method using the metallic zinc powder without the use of any metal catalyst or additives. The detailed structural and optical [...]
Atomistic Modeling for Boron Diffusion in Strained Silicon Substrate
Kim H-G, Kim J-S, Kim Y.K., Yoon K-S, Kim H-G, Kim J-S, Kim Y.K., Kim H-G, Kim J-S, Kim Y.K., Won T., Inha University, KR
We report our KMC study on the effect of strain on B diffusion in silicon and relaxed SiGe layer by assuming a virtual strained structure with charged defect energy and diffusivity. The simulation results imply [...]
Polyimides with Fluorenyl Side Groups and Their Unusual, Unique Alignability of Liquid Crystals at the Film Surface
Polyimides (PIs) have been widely used in the microelectronics industry as dielectric materials because of their advantageous properties. In the present study, we synthesized CBDA-FDA and its analogue, poly(4,4’-(9,9-fluorenyl)diphenylene pyromellitimide) (PMDA-FDA) and then investigated quantitatively [...]
Thickness-controlled Metal Nanoscale Etch for Proposed Metal Nanowires Fabrication
In this works, we developed a novel nanoscale etch process of metallic structures, the metal peel-off method(MPOM), to realize proposed fabrication of metal nanowires. Using this method, we simply and uniformly self-controlled etching rate of [...]
Nanoscale Device Modeling and Simulation: Multiple Independent gate Field Effect Transistor
we report our numerical modeling and simulation results for MIGFET. The simulation result revealed that MIGFET demonstrates dynamic modulation of sub-threshold swing and threshold voltage by biasing the second gate. And Short channel effects are [...]
Synthesis and Thin-Film Transistor Performance of Fluorene-based Copolymers Containing Thiophene Moieties Having Different Position of Alkyl Side Chain
We have synthesized fluorene-based copolymers (PF-HT-TT-TH and PF-TH-TT-HT) containing thiophene moieties having different position of alkyl side chain via the palladium-catalyzed Suzuki coupling reaction. The number-average molecular weight (Mn)s of PF-HT-TT-TH and PF-TH-TT-HT were respectively [...]
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 [...]
