CFD-Assisted Design and Optimization of a Pharmacokinetic Microfluidic System

Moeini Sedeh M., Khodadadi J.M., Hong J.W., Cramer K.A., Hamon M., Auburn University, US

In this research, a microfluidic system was designed and optimized to carry out in vitro pharmacokinetic studies of drug candidates in the liver. Computational fluid dynamics (CFD) was called on to assist in the system [...]

A Regional Model for Threshold Switching in Phase Change Memory

Wang L., Peking University Shenzhen Graduate Schoo, CN

In this paper, a regional model for threshold switching is presented based on the space charge effect in Phase Change Memory (PCM). In this model, the PCM unit is divided into two parts according to [...]

A Negative Index Metamaterial Waveguide for De-Multiplexing

Vidal X., Baev A., Furlani E.P., Prasad P.N., The Institute for Lasers, Photonics and Biophotonics, US

In this presentation, we propose a novel metamaterial-based waveguide coupler for use as a de-multiplexer at telecommunication wavelengths. Currently, there have been relatively few studies of guided modes in left-handed waveguides; these have indentified some [...]

Advanced physics for simulation of ultrascaled devices with UTOXPP Solver

Garetto D., Rideau D., Tavernier C., Leblebiciand Y., Schmid A., Jaouen H., IBM corp., FR

As the conventional scaling down of MOSFET dimensions faces physical and economical limits, the performances of novel solutions such as high-K dielectrics, mechanical strain and substrate orientation or alternative device structures, such as fully-depleted SOI [...]

Bottom-up device simulations: modeling electrical currents on the atomic scale

Blom A., Stokbro K., QuantumWise A/S, DK

As device features approach atomic dimensions, simulations of electrical currents need to be based on a quantum-mechanical description of the system. New phenomena then appear which can be exploited for novel device functionality, but also [...]

Performance Study of Nitride-Based Gunn Diodes

Aloise G., Vitanov S., Palankovski V., Advanced Material and Device Analysis Group, AT

In this work, we assess the performance of InN Gunn diodes, as a superior alternative to GaN. We perform two-dimensional mixed-mode device/circuit simulation accounting for self-heating effects. We verify available theoretical results for GaN-based Gunn [...]

Simulation of Field-Plate Effects on Surface-State-Related Lag and Current Slump in GaAs FETs

Tanaka T., Itagaki K., Nakajima A., Horio K., Shibaura Institute of Technology, JP

In this study, we carry out two-dimensional transient analysis of field-plate GaAs MESFETs by taking surface states into account. Quasi-pulsed current-voltage curves are derived from the transient characteristics. We show that drain lag and current [...]

Electromechanical and Electromagnetic Simulation of RF-MEMS Complex Networks Based on Compact Modeling Approach

Iannacci J., Faes A., Kuenzig T., Niessner M., Wachutka G., Fondazione Bruno Kessler - FBK, IT

RF-MEMS, i.e. MicroElectroMechanical-Systems for Radio Frequency applications, have been attracting the interest of the scientific community for more than one decade, thanks to their high performance and large reconfigurability. The employment of RF-MEMS based devices [...]

Design of Microassembly through Process Modeling in Virtual Reality

Das A.N., Stephanou H.E., University of Texas at Arlington, US

In this work we discuss how construction of microsystems via microassembly can be optimized through simulation of the entire process in virtual reality prior to actual execution. We exercise a holistic approach towards microscale manufacturing [...]

Simulation-Based Evolutionary Approach to Electrical Characteristic Optimization of Silicon Solar Cells

Lu Z-L, National Chiao Tung University, TW

Solar cell [1], which can provides renewable and clean energy by converting sunlight to electrical power, is one of the most promising energy technologies in order to relieve the impact of the climate change. Yet, [...]
