Now available: Seminar by Giulio Cerullo, coordinator of QUONDENSATE and professor atPolitecnico di Milano. His talk, titled "Ultrafast dynamics of 2D semiconductors and their heterostructures," was held at Utrecht University in February. In his talk, Giulio Cerullo reviewed recent studies on the ultrafast non-equilibrium optical response of TMDs and their heterostructures. Key points included monitoring the ultrafast onset of exciton formation in TMDs using ultrafast transient absorption (TA) spectroscopy, time-resolving intravalley spin-flip processes through helicity resolved TA spectroscopy, measuring ultrafast interlayer hole transfer and interlayer exciton formation in heterostructures of TMDs, and utilizing two-dimensional electronic spectroscopy to analyse interlayer electron and hole transfer processes. Host: Zeila Zanolli Abstract: Layered materials, consisting of crystalline sheets with strong in-plane covalent bonds and weak van der Waals out-of-plane interactions, exhibit unique physico-chemical properties when exfoliated to single layers, known as two-dimensional (2D) materials. These materials, including semiconducting transition metal dichalcogenides (TMDs), demonstrate strong light-matter interaction and intense nonlinear optical responses, enabling novel applications in optoelectronics and photonics. Moreover, stacking 2D materials into heterostructures (HS) offers vast opportunities to design new materials with tailored applications. The electronic structure of individual layers is preserved due to weak interlayer van der Waals coupling, while new physical properties and functionalities emerge based on the type, stacking sequence, and twist angle of the layers. hashtag #QUONDENSATE #2Dmaterials #Optoelectronics #Photonics #Semiconductors #Research #Innovation #ScienceEvents #Utrecht The full Seminar is available on Youtube: https://lnkd.in/dn7xvJec

Tuesday publication update! 📖 This publication in Small delves into the intricate world of 2D materials! Using the FusionAX, material behavior under high bias conditions can be observed at the nanoscale. ⚡️The structural evolution of monolayer MoS2 under intense biasing conditions was meticulously dissected at the atomic scale. The researchers captured and analyzed the dynamic interplay of electrons, shedding light on crucial insights that pave the way for transformative advancements in electronics and optoelectronics. 🔬One of the key things that was observed: Mo nanoclusters stemming from the disintegration of MoS2 and sulfur depletion, driven by the intense heat generated during biasing. This thermal stress left its mark in the form of long cracks, both in situ and ex situ. Join us in the pursuit of knowledge as we try and scale bulk experiments to nano, accelerate productivity and foster collaboration and growth!

Researchers developed a recipe for the room-temperature stabilization of thin films of α-Sn, a form of elemental tin that exhibits a variety of topologically nontrivial phases, but only at low temperatures. The study is an important contribution to the quest for new materials capable of replacing silicon in next-generation microelectronics. https://lnkd.in/gi-2sGNU

Check out our latest article at https://lnkd.in/eAUxWaXW, in which Tobias Bucher and co-workers answer a question that has been with the 2D-materials community for more than five years: Can we couple the valley degree of freedom of 2D-materials to a nanoantenna, to make it really usable for applications? Sadly, the answer is: NO. Why that is and what we learned on the way is dicussed in this collaboration work of the Friedrich-Schiller-Universität Jena, Abbe Center of Photonics, Max Planck School of Photonics, Fraunhofer IOF, FLEET: the ARC Centre of Excellence in Future Low-Energy Electronics Technologies, and Stanford University Department of Chemical Engineering. Congrats all the co-authors: Zlata Fedorova, Mostafa Abasifard, Rajeshkumar Mupparapu, Ph. D., Matthias Wurdack, Emad Najafidehaghani, Ziyang Gan, Dr. Heiko Knopf, Antony George, Thomas Pertsch, Andrey Turchanin, and Isabelle Staude. Should you not have time to read, here are my key takeaways: (1) coupling moving excitons to a stationary nanoantenna is like catching flies with your hands tied against your back. You are just too slow. (2) Results that defy your original goal need a lot of time to analyse. In this case the patience to stick with the experiments paied off. (3) Although ultimately successful and very rewarding for the PIs, data that needs five years (and many smart people) to understand can be a liabilty for PhD-students on strict 3-year tenures.

Solution-processable two-dimensional materials (2DMs) are attracting significant attention for their potential applications in logic, memory, and sensing devices.

How can we tell if a new technology is useful or useless? Here’s a story I’ve told in the past: Herbert Kroemer was a German-American physicist who received the Nobel Prize in Physics in 2000 for developing semiconductor heterostructures used in high-speed electronics and optoelectronics. But in 1963, he was working at Varian (one of the first high-tech companies in Silicon Valley) and proposed the concept of double heterostructure (DH) lasers. He wrote a paper and submitted it to APL where it was rejected. He then re-submitted it to APL where it was rejected again. He then re-submitted it to IEEE Letters where it was published, but ignored. When he proposed developing DH laser technology, he was refused the resources to do so on the grounds that “this device could not possibly have any practical applications.” Today, the entire optoelectronics industry depends on this technology. In life and in business, one of the most difficult things is to see opportunity. It’s the fog that stands between us and the future. As our world progresses, it is more important than ever to remind ourselves that we cannot judge the value of technology solely on the basis of how it can be used today. Imaginative people — once they have access to the technology — will always find a way to leverage it and bring them to a new horizon.
