In case you missed it: #QuMat seminar with Giulio Cerullo Ultrafast dynamics of 2D semiconductors and their hetero-structures Now on youtube! - https://lnkd.in/dn7xvJec Host: Zeila Zanolli Layered materials are solids consisting of crystalline sheets with strong in-plane covalent bonds and weak van der Waals out-of-plane interactions. These materials can be easily exfoliated to a single layer, obtaining two-dimensional (2D) materials with radically novel physico-chemical characteristics compared to their bulk counterparts. The field of 2D materials began with graphene and quickly expanded to include semiconducting transition metal dichalcogenides (TMDs). 2D materials exhibit very strong light-matter interaction and exceptionally intense nonlinear optical response, enabling a variety of novel applications in optoelectronics and photonics. Furthermore, stacking 2D materials into heterostructures (HS) offers unlimited possibilities to design new materials tailored for applications. In such HS the electronic structure of the individual layers is well retained because of the weak interlayer van der Waals coupling. Nevertheless, new physical properties and functionalities arise beyond those of their constituent blocks, depending on the type, the stacking sequence and the twist angle of the layers. This talk will review our recent studies on the ultrafast non-equilibrium optical response of TMDs and their HS. Using high time resolution ultrafast transient absorption (TA) spectroscopy, we monitor the ultrafast onset of exciton formation in TMDs [1] and the dynamics of strongly coupled phonons [2, 3]. Using helicity resolved TA spectroscopy we time-resolve intravalley spin-flip processes [4]. In HS of TMDs we measure ultrafast interlayer hole transfer [5], interlayer exciton formation [6] and use two-dimensional electronic spectroscopy to dissect interlayer electron and hole transfer processes [7].

Let us draw your attention to a recent publication on 𝗨𝗦𝗣 𝗹𝗮𝘀𝗲𝗿 𝗽𝗿𝗼𝗰𝗲𝘀𝘀𝗶𝗻𝗴 by the University of Applied Sciences Aschaffenburg, featuring the 𝗫𝗔𝗥𝗜𝗢𝗡 𝗢𝗽𝘁𝗶𝗰𝗮𝗹 𝗠𝗶𝗰𝗿𝗼𝗽𝗵𝗼𝗻𝗲 𝗘𝘁𝗮𝟰𝟱𝟬 𝗨𝗹𝘁𝗿𝗮. This research demonstrates the capabilities of our technology in monitoring micro-layer ablation on semiconductor components. Here are some key points: - Ultra-short-pulsed laser ablation of thin multilayer materials can be monitored using XARION’s Eta450 Ultra Optical Microphone. - Monitoring the material transition between polymer and copper during laser ablation is facilitated by observing a broad acoustic frequency spectrum between 100 kHz and 2 MHz in air, coupled with detecting a sudden change in acoustic energy. - A direct correlation was found between increased detected acoustic energy and a higher ablation rate.   We extend our appreciation to the team at TH Aschaffenburg University of Applied Sciences for their remarkable research, and we're honored to contribute to the advancement of real-time laser processing quality control. Stay tuned for further developments!   #XARION #THAschaffenburg #USPLaserProcessing #OpticalMicrophone #SemiconductorIndustry #Research #Innovation

The semiconductor and consumer electronics industries are two prominent adopters of laser microprocessing. These sectors benefit from the advantages that industrial lasers provide for various processes in the manufacture and refinement of wafers, displays, circuit boards, and other core components. The architectures of electronic components, in particular, consist of multiple layers, each potentially made of very different materials. Additionally, cleanliness must be ensured throughout the manufacturing process. Antonio Castelo, PhD explores the factors that compound the challenges faced by laser systems tasked with enabling such precision processing. And highlights companies that excel in this challenge like Litilit, Synova SA, Femtum, Center for Physical Sciences and Technology (FTMC), Akoneer, Precitec - Laser Material Processing, New Imaging Technologies (NIT) and PULSATE.

"As advancements in laser microprocessing flourish in the semiconductor sector, process monitoring, including via SWIR imaging, is further increasing the chances to achieve favorable outcomes in processing compact components. " "In the imaging domain, SWIR cameras are favored for semiconductor inspection due to the capability of SWIR light to "see" inside silicon to detect cracks and other potential wafer defects, or defects to solar cell panels. SWIR imagers are further used to perform failure analyses of integrated circuits. New Imaging Technologies’ (NIT’s) line-scan array camera solution, for example, which is based on an indium gallium arsenide detector, provides extremely sharp images of defects in materials at high throughput. This system achieves 2K resolution (2048 × 1 pixels at 7.5-μm pixel pitch). NIT has also recently launched a high resolution SWIR sensor for the most demanding inspections in this field, with an 8-μm pixel pitch and 2-MP resolution at 1920 × 1080 pixels. This solution achieves ultralow noise of 25 e- to ensure image clarity even in challenging environments."

𝗦𝗲𝗰𝗿𝗲𝘁 𝗼𝗳 𝗠𝗲𝗺𝗿𝗶𝘀𝘁𝗼𝗿 𝗠𝗮𝘁𝗲𝗿𝗶𝗮𝗹 𝗥𝗲𝘃𝗲𝗮𝗹𝗲𝗱 🔊 A memristor that stores digital and analogue data and inherently processes has never been existed before in this form. Until Prof. Dr Heidemarie Schmidt and her team at the Helmholtz-Zentrum Dresden-Rossendorf conducted research into the magnetic properties of materials - and in 2011 discovered an iron-based material that corresponded to the theoretical properties of a memristor described by global science. The newly discovered material offered all the prerequisites for an electronic device with a unique device-specific link between electric charge and magnetic flux. With the help of SPRIND - Bundesagentur für Sprunginnovationen, we managed to get a strong partner on board with whom we are able to think bigger and to address the special aspects of industrial production. With our TiF-MEMRiSTOR semiconductor material innovation, TECHiFAB is among the top three leap innovations supported by SPRIN-D and has since been on its way out of the laboratory and into the industrial upscaling of memristor production. First TiF-MEMRiSTOR chips and the corresponding measurement device are available and can be ordered from TECHiFAB. #hardware #electronics #edgeai #memristor #sensorics
