Modeling microdrop motion between covered and open regions of EWOD microsystems

Berthier J., Clementz Ph., Roux J-M, Fouillet Y., Peponnet C., CEA-LETI, FR

Digital microfluidics is a promising way to manipulate biological targets like DNA, proteins or cells in very small liquid volumes. The advantages of such devices are the use of lesser quantities of costly reagents, better [...]

Designing Opto-Electronic Nanomaterials Using First Principles Simulations

Williamson A.J., Lawrence Livermore National Laboratory, US

The results of recent first principles simulations of the structural and opto-electronic of semiconductor nanomaterials will be presented. We will show how the opto-electronic properties of silicon nanomaterials can be controlled by altering their size, [...]

Phonon Scattering in Doped Silicon by Molecular Dynamics Simulation

Yao M., Watanabe T., Phillpot S.R., Schelling P.K., Keblinski P., Cahill D.G., University of Florida, US

Molecular dynamics simulation is used to study the scattering of phonon wave packets of well–defined frequency . The simulation system is 22 unit cells in the direction normal to phonon propagation and 3000 unit cells [...]

New One-Particle Monte Carlo Method for Nanoscale Device Simulation

Brugger S.C., Schenk A., Swiss Federal Institut of Technology, CH

A new one-particle Monte Carlo iteration scheme has been found toself-consistently take into account generation-recombinationprocesses. The basic idea is to couple the BTE not only with thePoisson equation, but also with the continuity equation by [...]

Study of the RF Characteristics features of Optimized SOI – MESFETs

Tarik K., Vasileska D., Thornton T.J., Arizona State University, US

We have already demonstrated that the SOI MESFET device structure is a suitable candidate for micropower circuit applications due to its high anticipated cut-off frequency . Even though the device offers higher fT, there is [...]

Technique for Time and Frequency Dependent Solutions of the Diffusion Equation: Application to temperature of nanoscale devices

Forbes L., Wanalertlak W., Louie M.Y., Oregon State University, US

Typical CMOS device currents have remained around 1mA/um while devices have scaled down. The projection into the 2010 time frame is 0.01um or 10nm dimensions with 0.5V power supplies which results for a minimum dimension [...]

Molecular Simulation Studies on Adsorption of Mercuric Chloride

Kotdawala R.R., Kazantzis N., Thompson R.W., Worcester Polytechnic Institute, US

The need to develop technologies capable of achieving high removal efficiencies for mercury chloride emission control led many researchers to focus their attention on the evaluation of the adsorption capacity and selectivity shown by different [...]

Computations on Ba@C74 and Yb@C74

Slanina Z., Nagase S., Institute for Molecular Science, JP

Computations of C74 and Yb@C74 are reported. C74 exhibits just one IPR (isolated-pentagon-rule) structure, however, there are several C74 non-IPR cages with a relatively low energy. C74 is represented here by six cages. The computations [...]

Model of a Liquid Nanofilm on a Solid Substrate

Akhatov I., Gavrilyuk S., North Dakota State University, US

Van der Waals attractive forces drastically change the material properties of thin layers several nanometers when in contact with a solid. At this scale, the fluid is no longer homogeneous. Moreover, it has properties which [...]

Multi-scale Discrete Dislocation Plasticity Analysis: Application to Nano-indentation

Khan S.M.A., Levine L.E., National Institute of Standards and Technology, US

With the growing utilization of nano-scale components in various technologies like MEMS, NEMS, thin films, medical diagnostics etc, nano-indentation testing is finding new expanding applications towards quantitative determination of mechanical properties at the nano-scale. In [...]
