Hybrid session live-streaming from in-person workshop "Novel (2D) Materials & Their Applications" in Aachen, Germany


The 2D-PL workshop Advanced Characterisation Methods workshop highlights the latest innovations in analysing and advancing 2D materials, presented in a hybrid format with live streaming as it is embedded in the in-person workshop "Novel (2D) Materials and Their Applications" in Aachen. The session opens with an introduction to the 2D-Pilot Line project, the follow-up to the 2D-EPL, focusing on scalable production and integration of 2D material technologies. Abbas Mohtashami from TNO, one of the new partners of the 2D-PL, presents advancements in Scanning Nitrogen-Vacancy Microscopy as a high-resolution characterisation tool for 2D material devices. The final talk, contributed by Gertjan van Baarle (LPM) and project partner of 2D Engine, delves into in-situ tools for real-time characterization and manipulation of 2D materials during and after growth on liquid metal catalysts via CVD. Join us online and gain valuable insights into the forefront of 2D materials research and technology.

Scanning Nitrogen-Vacancy Microscopy: A developing tool for characterisation of 2D material devices (Abbas Mohtashami)

Abstract: Scanning nitrogen-vacancy microscopy (SNVM) is emerging as a novel metrology tool for the characterisation of 2D-material based devices. In this talk, I will introduce the principles of NV microscopy and demonstrate its application for in-operando mapping of current density in 2D-material devices. The unique ability of SNVM to image current distribution with high spatial resolution, even through optically non-transmissive layers, provides critical insights on local defects and charge transport mechanisms in 2D devices, making SNVM a valuable tool for advancing the development of 2D devices and electronics.

Development of in-situ tools for characterization and manipulation of 2D materials during and after growth on liquid metal catalysts by CVD (Gertjan van Baarle)

Abstract: In this talk we discuss the development of CVD reactors for 2D material growth on liquid metal catalysts compatible with in-situ characterisation of the growth. The in-situ characterisation includes X-ray and optical techniques. We will show examples of how such tools can greatly enhance understanding of the nucleation and growth modes and is a great tool for the optimisation of the growth recipe, yielding fully covered samples with low-defect density graphene. We will also present the in-situ tools we developed allowing mechanical interaction with the as grown graphene on liquid Cu. Finally, we will discuss the ongoing developments on extending the work on other 2D materials.
