New Characterisation Techniques for the Study of Nanoscale Polymeric Systems in Two- & Three-Dimensions

Stokes D.J., Reyntjens S., Jiao C., Hayles M.F., Hubert D.H.W., FEI Company, NL

Activity in the development of polymer-based materials, composites and devices is more intense than ever. At the same time, techniques and methods for their characterisation have become more powerful, giving new insights into the spatial [...]

Nanotechnology Patent Mapping

Michalitsch R., Kallinger C., Veefkind V., Verbandt Y., Scheu M., European Patent Office, NL

As a consequence of large public and private investments in new technologies at the nanoscale, over the last years an increase in the filing numbers of European and PCT patent applications related to nanotechnology has [...]

High resolution Nanolithography using Focused Ion Beam Scanning Electron Microscopy (FIB SEM)

Wilhelmi O., Roussel L, Stokes D.J., Hubert D.H.W., FEI Company, NL

State-of-the-art FIB technology combined with high-performance SEM is making a big impact on nanotechnology, particularly with the ability to use either focused ions or electrons to perform advanced nanolithography. Achieving the highest standards requires an [...]

A Unified Parameter Extraction Procedure for Scalable Bipolar Transistor Model Mextram

Wu H.C., Mijalkovic S., Burghartz J.N., Delft University of Technology, NL

A unified parameters extraction procedure for temperature and geometry scalable bipolar transistor model Mextram has been demonstrated using an example of high-speed SiGe HBT technology. The essential feature of the proposed methodology is a direct [...]

A transient circuit model for a phase change memory element

Huizing H.G.A., Tio Castro D., Paasschens J.C.J., Lankhorst M.H.R., Philips, NL

A transient lumped element model for a phase change memory (PCM) cell is developed for use in a circuit simulator. Unlike existing models, this model calculates threshold voltage and off-state resistance drift as found in [...]

High-Voltage LDMOS Compact Modeling

Willemsen M.B., van Langevelde R., Klaassen D.B.M., Philips Research, NL

In compact modeling of high-voltage LDMOS devices often a sub-circuit approach is used. While for the channel region a standard compact MOS model (for example BSIM4, MM11 or PSP) is used, the drift region is [...]

III-V semiconductor nanowires grown on silicon for vertical devices

Helman A., Borgström M., Wunnicke O., van den Einden W., Verheijen M.A., Roest A.L., Bakkers E.P.A.M., Philips Research Laboratories, NL

The integration of III-V semiconductor nanostructures to silicon technology still represents a challenge. In this work we explore the potential of III-V semiconductor nanowires grown on silicon for the fabrication of electronic devices such as [...]

Nano-structuring of isotactic polypropylene in presence of a self-assembling nucleating agent under defined flow conditions

Balzano L., Rastogi S., Peters G., Technical University Eindhoven, NL

Presence of additives in polymers plays an important role in physical and mechanical properties. For an example DMDBS is one of the frequently used additives in polypropylenes. The additive is used to achieve higher transparency [...]

Dissolution of Hydrogen Bonded Polymers in Water: From Synthetic to Biopolymers

Rastogi S., Vinken E., Harings J., Yin J., Terry A., Eindhoven University of Technology, NL

The field of supramolecular materials explores the use of intermolecular, non-covalent bonding to obtain novel self-assembled structures. Self-assembly is a method of spontaneous organisation of molecules into higher order structures ranging from the nano to [...]

Lattice Boltzmann simulation of emulsification in microfluidics devices

van der Graaf S., van der Sman R.G.M., van der Graaf S., van der Sman R.G.M., Wageningen University, NL

Using microdevices we investigate the manufacturing of surfactant stabilised monodisperse food emulsions. Design of the process is a complicated matter, involving knowledge of wetting behaviour, droplet breakup in confined systems, surfactant dynamics coupled to droplet [...]
