Industry Advisory Board:

The Industry Advisory Board advises the Research Unit and discusses all issues concerning its work, in particular those relevant to the transfer of results into application.

The members of the Industrial Advisory Board are:

  • XFAB Silicon Foundries SE (supporting the research group in the development of integrated sensor and evaluation solutions),
  • Umwelt- und Sensortechnik UST GmbH (viewpoint of industry-related sensor technology),
  • FBGS Technologies GmbH (market leader for the development of sensor fibers as well as the integration of sensory components in optical fibers),
  • Analytik Jena (support in the field of combustion analyzers).

Contents and goals

2D materials consist almost exclusively of surfaces and therefore interact extremely strongly with their environment. This makes them ideal for nanoscale and quantum-sensitive applications. Due to their strong interaction between light and matter, it is equally possible to read their status even from a distance.

Other properties of TMDs that are of particular interest for 2D sensing include:

  • Strong interaction with gases already at room temperature,
  • Possibility of realizing controllable emitters for quantum light,
  • Extremely strong optical nonlinearities.
 

The aim of 2D-Sens is to exploit the properties of transition metal dichalcogenides (TMDs) specifically for gas sensors and to design, fabricate and characterize four types of innovative TMD-based gas sensors.
