Germany’s RWTH Aachen University and AMO launch joint Aachen Graphene & 2D-Materials Center

RWTH Aachen University and AMO GmbH in Germany have launched a new joint research center with a focus on efficiently bridging the gap between fundamental science and applications within graphene and related materials-based electronics and photonics.
Sharing the vision of bringing graphene and related materials research from the lab into applications, the five founding principal investigators of the Aachen Graphene and 2D-Materials Center (who are also all members of the EU-funded Graphene Flagship project) are professor Christoph Stampfer (of RWTH, and spokesman for the center), professor Max Lemme (of AMO and RWTH), professor Markus Morgenstern (of RWTH), professor Renato Negra (of RWTH) and Dr Daniel Neumaier (of AMO).
“The center will help to turn the exciting properties of graphene and 2D [two-dimensional] materials into true functions, making these materials not only fascinating for scientists but also serving society,” said Christoph Stampfer following the center’s kick-off meeting on 24 July. “With the Aachen Graphene and 2D-Material Center, we aim at increasing the visibility of Aachen as an excellent place to undertake graphene and 2D material research with both a fundamental and applied focus.”
The center enables the integration of the already ongoing work from RWTH Aachen University and AMO under a legal framework that allows for full collaboration between the groups. In particular, the center will focus on addressing the challenges of future technology including high-frequency electronics, flexible electronics, energy-efficient sensing, photonics as well as spintronics and valleytronics with graphene and related materials and their heterostructures.
Founding Members of the Aachen Graphene and 2D Materials Center:
  • Prof. Christoph Stampfer, RWTH Aachen University (Spokesman)
  • Prof. Max Lemme, RWTH Aachen University/AMO GmbH
  • Prof. Markus Morgenstern , RWTH Aachen University
  • Prof. Renato Negra, RWTH Aachen University
  • Dr. Daniel Neumaier, AMO GmbH

[paper] Improvements to a compact MOSFET model for design by hand

Improvements to a compact MOSFET model for design by hand
A. de Jesus Costa, F. Martins Cardoso, E. Pinto Santana and A. I. Araújo Cunha
15th IEEE NEWCAS
Strasbourg, France, 2017, pp. 225-228
doi: 10.1109/NEWCAS.2017.8010146

Abstract: In this work, an improved version of the basic structure of a compact MOSFET model and the respective parameters extraction methodology are proposed. The aim of this approach is to increase accuracy in hand calculations for analog circuit design without significantly increasing its complexity. The influences of both inversion level and channel length are considered in the modeling of a few features such as mobility, threshold voltage and onset of saturation. Simple design examples of current sinks and sources are accomplished to compare the basic and the improved models [read more...]

[paper] Compact Electro-Mechanical-Fluidic Model for Actuated Fluid Flow System

Compact Electro-Mechanical-Fluidic Model for Actuated Fluid Flow System

M. Miura-Mattausch, Fellow, IEEE, and H. J. Mattausch, Senior Member, IEEE
in IEEE Journal on Multiscale and Multiphysics Computational Techniques, 
vol. 2, no. , pp. 124-133, 2017.
doi: 10.1109/JMMCT.2017.2731878

Abstract: This paper presents a compact electro-mechanical-fluidic system-modeling method for multidomain system simulation based on multidomain physics that considers the total energy conservation condition, in terms of respective potential and flow quantities. Models for electrical, mechanical, and fluidic domains are developed to design the example of a blood pumping system, where the blood flow is driven by electrically controlled organic actuators. The electrical domain includes an organic mosfet-based control circuit, the mechanical domain includes organic actuators, and the fluidic domain includes a flexible fluid-flow channel. Control circuit, actuators, and fluid models are coupled through equivalent circuits, where interconnection relationships between two neighboring domains are expressed using the energy conservation concept. The model accuracy is verified with finite element method (FEM) based numerical simulation. Significantly faster simulation speed than with FEM and good accuracy were achieved [read more...]
