Abstract:

Graphene and related two-dimensional materials like MoS2 or WSe2 have emerged some 15 years ago as promising options for electronic, photonic and sensor devices. Possible applications in these fields include solutions for continuing the down-scaling of logic devices (Moore’s law), high frequency electronic circuits, ultrafast optoelectronics for optical communication and flexible electronics. In this talk I will give an overview on the field in these areas including recent results, outlining not only the potential of 2D materials but also the challenges and main limitations. 

One key requirement for a commercial success of these devices is large volume production, i.e. wafer-scale processing, which needs to be developed and mastered. While wafer scale growth of graphene and related 2D materials has been demonstrated by means of chemical vapor deposition or similar methods, the transfer of such grown 2D layers to target substrates still faces severe challenges related to contamination, mechanical stress and reproducibility. In addition, defining and controlling quality, yield and reproducibility of (opto-)electronic devices is at a very early stage.
