2D materials display very promising intrinsic material properties, with multiple applications in electronics, photonics, and sensing. In particular layered platinum diselenide has shown high potential due to its layer-dependent tunable bandgap, low-temperature growth, and high environmental stability.

In this article published in Advanced Functional Materials, partner UniBW demonstrates the viability of this new approach to controlled fabrication of hybrid devices with 2D material by the manufacture of a highly sensitive ammonia sensors channel with 3D topography and fully integrated infrared-photodetectors on silicon photonics waveguides.

The new developed methodology demonstrates versatility and applicability and lays the foundation for new design routes for the synthesis of more complex hybrid structures with 2D materials.
