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.
