Processing technologies for semiconductor nanowire-based sensors with high throughput

The aim of the BMBF-funded WireControl project (1.3 million €) is to provide the theoretical and the technological basis for developing novel nanowire based gas sensors with high selectivity and sensitivity. The major focus is devoted to achieve reproducible fabrication of large-area, regularly arranged and aligned nanowire building blocks for new device platforms via practical processing approaches.

The WireControl Project is coordinated by TU Braunschweig and brings together four Project Partners with multidisciplinary background.

Project Partners in WireControl:

  • Prof. Andreas Waag, Institut für Halbleitertechnik, TU Braunschweig
  • Prof. Franz Kreupl, FG Hybride Elektronische Systeme, TU München
  • Prof. Bernd Witzigmann, Computational Electronics and Photonics Group, Universität Kassel
  • Prof. Michael Moseler, Functional Nanosystems Group, Universität Freiburg

The TU-Braunschweig is developing new fabrication and processing paradigms for GaN nanowires as well as tailoring their surface properties via chemical modification to produce highly selective and sensitive gas sensors especially toward NOx family of toxic gases (e.g. NO2, NO, etc.). TU-Munich subproject is investigating the synthesis of Carbon nanotubes on large area substrates. The University of Kassel is modeling possible device component geometries using complex multiscale simulation. The University of Freiburg is developing theoretical approaches to predict the selectivity and sensitivity of such nanosensors, which is particularly helpful for a specific device designs. The research of WireControl project will initiate a reliable basis for future industry-led implementation of nanowire technology in products.

Interested industrial partners are invited to contact the WireControl consortium.
