Novel Computing Architecture on Arrays of Josephson Persistent Current Bits

Han J., Jonker P., Delft University of Technology, NL

A superconducting qubit (or quantum bit), which consists of a micrometer-sized loop with three Josephson junctions, has two persistent currents of opposite direction as its two states. The states of the qubit can be brought [...]

Using Scalar Algebraic Multigrid Solvers for Efficient 3-D Stress Analysis of Microfabricated Structures

Mijalkovic S., Delft University of Technology, NL

A methodology to improve the performance of iterative solvers in 3-D stress analysis using scalar algebraic multigrid (AMG) solvers has been presented. The principle idea is to split the global system of coupled stress governing [...]

Analytical Modelling for Accelerometers with Electrically Tunable Sensitivity

Cretu E., Bartek M., Wolffenbuttel R.F., Delft University of Technology, NL

Results of the analysis and modelling of a pendulum type of accelerometer in an electrostatic field are presented. A common-mode voltage is used to yield an electrostatic positive feedback that amplifies the mechanical sensitivity. The [...]

Load-Deflection of a Low-Stress SiN-Membrane/Si-Frame Composite Diaphragm

Correia J.H., Bartek M., Wolffenbuttel R.F., Delft University of Technology, NL

Finite-Element-Methods (FEM) has been used to study the behavior of a non-planar composite diaphragm, which is to be used in a tunable Fabry-Perot-based silicon microinterferometer. The composite (Ag-mirrorAow-stress SiN membrane/Si-frame) diaphragm used exhibits: excellent flatness, [...]
