Electrical Transport through Single-molecule Junctions: From molecular orbitals to conduction channels

Heurich J., Cuevas J.C., Wenzel W., Schön G., Forschungszentrum Karlsruhe, DE

Present trends in the miniaturization of electronic devices suggest that ultimately single molecules may be used as electronically active elements in a variety of applications. Recent advances in the manipulation of single molecules now permit [...]

Compatible Hole Channel Mobility and Hole Quantum Correction Models for the TCAD optimization of Nanometer Scale PMOSFETs

Nguyen C.D., Jungemann C., Neihues B., Meinerzhagen B., Sedlmeir J., Molzer W., ITEM-University of Bremen, DE

In this work a quantum correction model for the hole inversion layer based on the Improved Modified Local Density Approximation (IMLDA) and a corresponding channel mobility model compatible to the IMLDA quantum corrected spatial p-density [...]

Adaption of the 3w-Method for Testing of MEMS

Raudzis C., Schatz F., Wharam D., Corporate Research, Robert Bosch GmbH, DE

Automated wafer level testing of MEMS requires methods to measure geometry and material related parameters by purely electrical means. The three omega method to measure the thermal conductivity seems to be appropriate for this task. [...]

Simulation of a Diamond-Based Bistable Thermal Microswitch

Schmid P., Hernandez-Guillen F.J., Kohn E., University of Ulm, DE

A novel bistable layout for a thermally driven microswitch based on polycrystalline diamond has been developed and evaluated by simulations. The device is based on a double-anchored, free standing diamond beam, which buckles due to [...]

New Micro Hydro Power Device

Pobering S., Schwesinger N., Münich University of Technology, DE

We have focused our research to new principles of converting energy by means of microstructured components. It is possible to extend the usable water power recourses by converting the kinetic energy directly. This type of [...]

Mixed-Level Model for Highly Perforated Torsional Actuators Coupling the Mechanical, the Electrostatic and the Fluidic Domain

Sattler R., Schrag G., Wachutka G., Institute for Physics of Electrotechnology, DE

Electrostatic attraction between neighboring electrodes is a widely used actuation principle employed in tiltable micromirrors or microrelays. Electrostatic actuation is especially favored for switching applications in mobile telecommunication because of its low power consumption. State-of-the-art [...]

CFD-based Optimization of Gas/Liquid Microreactors with Droplet and Bubble Transport

Hardt S., Pennemann H., Jiang F., Institute of Microtechnology Mainz, DE

Microreactors offer unique opportunities for the control of process parameters unparalleled by macroscopic equipment. A new gas/liquid microreactor is proposed allowing for fast mass transfer and small concentration gradients as well as a very narrow [...]
