Abstract: Two dimensional materials exhibit exceptional physical and chemical properties which can be further enhanced and enriched via the controlled functionalization with molecules and (supra)molecular assemblies thereof yielding hybrid systems with ad hoc characteristics for applications in (opto)electronics, sensing and energy. Molecules can be designed and synthesized in order to physisorb or chemisorb onto 2D materials in a controlled fashion.
In my lecture I will review our recent findings on the functionalization of 2D materials to engineer hybrid systems via:
- physisorption of molecular switches onto the two surfaces of scotch tape and CVD 2D ambipolar semiconductors, following a Janus approach, as a route to confer two distinct and additional properties to WSe2, rendering the 2D material-based transistors capable to respond to three different independent stimuli.
- chemisorption of doubly-thiolated molecules onto solution-processed semiconducting transition metal dichalcogenides as a way to simultaneously heal sulfur vacancies in metal disulfides (MS2) and covalently bridge adjacent flakes, thereby promoting percolation pathways for the charge transport, leading to an increase by one order-of-magnitude in field-effect mobility, ION / IOFF ratio, and switching times of liquid-gated transistors.
Our modular strategies relying on the combination of 2D material with molecules offer a simple route to generate multifunctional 2D materials-based coatings, foams and nanocomposites with pre-programmed properties to address key global challenges in electronics, sensing and energy applications.
Bio: Dr. Zhenxing Wang, head of the Graphene Electronics Group at AMO GmbH, is a new member of the Aachen Graphene & 2D Materials Center.
Wang’s research activity focuses on the development of graphene-based electronics, especially for high frequency applications, as well as on the wafer scale integration of graphene material. He is leading different German national projects (e.g. DFG project: HiPeDi, MOSTFLEX) as well as EU international projects from AMO side (Graphene Flagship, 2D-EPL, G-Imager, WiPLASH and GreEnergy – starting in Jan. 2021).
On his background, Wang has a PhD from Peking University on radio-frequency electronics based on graphene and carbon nanotubes, and a Post-Doc at the University of Erlangen- Nuremberg, where he also worked on graphene and self-assembled monolayers.
Abstract: Graphene has great potentials for applications in different fields such as electronics, optoelectronics, and sensors. However, the final functional application still relies on the state-of-the-art platform such as silicon technology process line, due to its maturity for circuit and system realization. Therefore, a path to integrate graphene to such traditional fabrication platform needs to be developed, in order to make the fancy material closer to reality. In this presentation, graphene processing will be introduced from different technology aspects, such as material growth, transfer, interface treatment, doping control, electrical contact optimization. The status and progress at AMO will be introduced. The new project 2D Experimental Pilot Line will be introduced, the target of which is to facilitate Graphene foundry service to public in Europe.
Bio: Titus Neupert has worked as a professor of theoretical solid state physics at the University of Zurich since 2016. His research investigates the topological phases of matter using analytical and numerical methods. He completed his studies at the University of Zurich in 2009 before taking a one-year guest researcher position at RIKEN in Japan. In 2013, he finished his doctorate at the University of Zurich. His doctoral research, mainly conducted at the Paul Scherrer Institute, focused on the realization of fractional quantum Hall phases in lattice models. Titus Neupert then spent three years as a postdoctoral researcher at the Princeton Center for Theoretical Science, USA, where he analyzed Weyl semimetals and platforms for topological quantum computers in superconductors. Back at the University of Zurich as a professor, he established the working group Condensed Matter Theory and received an ERC Starting Grant in 2017, which supports his research on higher-order topological insulators.
Abstract: Topological quantum matter is a very active research direction in condensed matter physics. Over the past two decades, many topological materials have been identified in a tight interplay between theory and experiments. In this process, the theoretical framework, in particular topological band theory, has been continuously refined. In this talk I will give an overview of our current understanding of topological classifications of electronic bands, with a focus on two-dimensional materials. In particular, I will discuss the differentiation between atomic insulators, so-called delicate topology and fragile topology. As a concrete example, I will discuss how graphene, when decorated with adatoms, can host fragile topological flat bands. I will contrast these bands with the ones arising in moiré heterostructures.
Bio: Talieh S. Ghiasi received her Bachelor’s and Master's degrees in solid-state physics at Iran University of Science and Technology (2014). She got her second Master's degree in Nanoscience at the University of Groningen, the Netherlands (2016). For her Ph.D., she worked with Prof. Bart van Wees at Zernike institute. The highlights of her Ph.D. research (2016-2020) are the proximity-induced spin-orbit coupling and magnetism in graphene, including the experimental realization of anisotropic spin transport, charge-to-spin conversion mechanisms, spin-polarization of conductivity, and spin-dependent Seebeck effect in graphene. She is currently a postdoctoral researcher at the University of Groningen, working on spin and magnon transport in two-dimensional magnetic materials.
Abstract: In graphene-based van der Waals heterostructures, the superior spin and charge transport properties of graphene are enriched via the proximity to other 2D materials. By the proximity effects, one can induce spin-orbit and magnetic exchange interactions in the graphene which provide strong coupling between charge and spin currents. In particular, our recent investigation of spin transport in graphene in the proximity of a 2D interlayer antiferromagnet CrSBr has shown strong spin polarization of conductivity in graphene (∼14%). The spin-dependent conductivity arises from a large induced exchange interaction that also results in the observation of spin-dependent Seebeck effect in graphene. This is the first-time experimental realization of the active role of magnetic graphene in the electrical and thermal generation of spin currents, addressing the most technologically relevant aspects of the induced magnetism. The spin-dependent conductivity and Seebeck coefficient, together with the long-distance spin transport introduce magnetic graphene as an ultimate building block for ultra-compact magnetic memory and sensory devices and can provide substantial advances in 2D spintronic/caloritronic technology.
