Shear Piezoresistance Coefficient Pi44 of n-type Silicon

Kanda Y., Matsuda K., Kojundo Chemical Laboratory Co. LTD, JP

The PR in silicon has been widely used in the framework of micro-electro mechanical systems (MEMS). Origin of the shear PR effect even in n-type Si was not always explained completely in despite of simpler [...]

Numerical Study of Flame Acceleration in Microchannel

Chaudhuri A., Guha C., Dutta T.K., Jadavpur University, IN

Phenomenon of flame acceleration of premixed combustible air-acetylene mixture towards the open end of adiabatic microchannel has been studied by solving Navier-Stokes (NS) system of equations with single step chemistry model. A two dimensional unsteady [...]

Adaptive Energy Integration of Non-Equilibrium Green’s Function

Baumgartner O., Karner M., Holzer S., Pourfath M., Grasser T., Kosina H., TU Wien, AT

Within the non-equilibrium Green's function formalism numerical integration plays an important role. Several adaptive integration methods were realized and compared regarding convergency within a self-consistent Schrödinger-Poisson loop, computation time and memory consumption.

The effect of damping for the rate of flow in the micropump

Lan W.P., Chang J-S, National Taiwan University, TW

This research is about identifying the optimal working frequency for valveless pump and comparison with experiment data. The fluid-solid membrane brings about different mode change as the work frequencies change. When the micropump work at [...]

Reduced-order modelling of the Reynolds equation for flexible structures

Missoffe A., Juillard J., Aubry D., SUPELEC, FR

A reduced-order modelling technique for the Reynolds equation - which governs squeeze-film damping in MEMS structures - is presented in this paper. It is valid for flexible structures and large displacements, the only hypothesis made [...]
