The CVD-based growth of 2D-materials, such as TMDs, used to be spray&pray. Crystals would grow all over your sample, without any measure of control. In a new publications in Small Methods, we show controlled and localized growth of monolayer MoS2 and MoSe2 and optical & optoelectronic apps.

This semester has seen the prototype instalment of our new "Experimental Quantum Technology" lab course. We think it was great and will be the first of many. Fraunhofer IOF shares or thoughts and ideas and even released a press stament on the matter.

We can announce the start of the BMBF-funded joint research project tubLAN Q.0​, in which we will focus on the fiber intergration of single photon sources.
Exposed core fibers functionalized with 2D-Materials are scalable platform for photonics.

The first part of the prototype lab course "Experimental Quantum Technologies" is finished. We did a hands-on demonstration of quantum enhanced phase sensing and solved equations with Grover's algorithm. Student Results have been great. Teaching materials available.
