Single Wall Carbon Nanotube-Based Structural Health Monitoring Sensing Materials

Watkins A.N., Ingram J.L., Jordan J.D., Wincheski R.A., Smits J.M., Williams P.A., NASA Langley Research Center, US

Single-wall carbon nanotube (SWCNT)-based materials represent the future aerospace vehicle construction material of choice based primarily on predicted strength-to-weight advantages and inherent multifunctionality. As such, it is prudent to pursue the development of SWCNT-based sensing [...]

A Study of the Threshold Voltage Variations for Ultra-thin Body Double Gate SOI MOSFETs

Tang C-S, Lo S-C, Lee J.W., Tsai J-H, Li Y., Natl Nano Device Labs & Natl Chiao Tung Univ, TW

Double gate silicon on insulator (SOI) devices are more and more attractive for sub-50 nm ultra-large scaled integrated (ULSI) circuits manufacturing. The double gate SOI devices, owing to a difficulty of manufacturing uniformity, suffer fluctuations [...]

Kinetic Monte Carlo Modeling of Boron Diffusion in Si Crystalline Materials

Seo J., Hwang C-O, Kwon O., Kim K., Won T., School of Engineering, Inha University, KR

In this paper, we report a lattice-free kinetic Monte Carlo (KMC) result of boron diffusion at low temperatures 450o and 550o with vacancy + interstitialcy mechanism or vacancy + kick-out one with dilute self-interstitials (I) [...]

2D Quantum Mechanical Device Modeling and Simulation: Single and Multi-fin FinFET

Kim K., Kwon O., Seo J., Won T., Inha University, KR

A two-dimensional quantum mechanical modeling has been performed to simulate a nano-scale FinFET by obtaining the self-consistent solution of coupled Poisson and Schrödinger equations. Calculated current-voltage (I-V) curves are carefully compared with experimental data to [...]

Molecular Dynamics (MD) Calculation on Ion Implantation Process with Dynamic Annealing for Ultra-shallow Junction Formation

Kwon O., Kim K., Seo J., Won T., Inha University, KR

In this paper, we report a molecular dynamics (MD) simulation of the ion implantation for nano-scale devices with ultra-shallow junctions. In order to model the profile of ion distribution in nanometer scale, the molecular dynamics [...]

Numerical Simulation of Electronic Properties in Quantum Dot Hheterostructures

Vlahovic B., Filikhin I., Suslov V.M., Wang K., North Carolina Central University, US

Because of the strong dependence of energy level on the geometry and sizes, the quantum dots are perfect candidates as high efficiency photovoltaic solar cells. Efficiency of 63.2% solar cell has been predicted by theoretical [...]

Design and Development of Nano-reinforced Bonds and Interfaces

Sun Y., Meguid S.A., Liew K.M., Ong L.S., University of Toronto, CA

This investigation focuses on the design and development of nano-reinforced adhesively-bonded high performance joints. The influence of homogeneous dispersion of carbon nanotubes and alumina nanoparticles on the cohesive strength, interfacial properties and mechanical behaviour of [...]

Thin Film Instability and Nanostructure Formation: a Molecular Dynamics Study

Han M., Lee J.S., Park S., Choi Y.K., Seoul National University, KR

One of the recent studies showed that the structures can be self-constructed by controlling the instability of thin fluid film of a nano-scale [S.Y. Chou and L. Zhuang, , J. Vac. Sci. and Technol. B, [...]

Optical Absorption Modeling of Arbitrary Shaped Nanoparticles

Mullin P., Kozlowski G., Kozlowski P.G., Kozlowski G., Kozlowski P.G., Busbee J.D., Jones J.G., Wright State University, US

A method for modeling the optical absorption spectra of nanosize metal particles is demonstrated. Computer software has been developed to generate the absorption spectra from the particles geometry and material properties. The software breaks the [...]

Modeling of PDMS – Silica Nanocomposites

Smith G.D., Smith J.S., Smith G.D., Smith J.S., Borodin O., University of Utah, US

A hydrogen bonding pathway between polydimethylsiloxane (PDMS) and hydroxyl groups on a silica surface was studied using quantum chemistry calculations of disiloxane and hexamethyldisiloxane molecules with small silica clusters. A newly developed classical force field [...]
