2022 Virtual EDS Brazil Mini-colloquium (part 1)
On August 22nd the Centro Universitario FEI ED Student Branch Chapter organized the 2022 EDS (Virtual) Brazil Mini colloquium. The Mini colloquium will have 4 presentations given by EDS Distinguished Lecturers, covering state-of-art topics in micro/nanoelectronics, from modeling of nanosheets to heterogeneous integration, passing on neuromorphic computing, quantum computing, and 2D materials.
Because of the outbreak restrictions, the Mini colloquium will be held virtually. Also, it will be broadcasted live via Brazilian Microelectronics Society social media.

Augmenting silicon technologies with graphene
Harnessing graphene’s properties on a silicon platform could augment integrated technologies with a broad range of novel miniaturized functionalities. We will review the learnings from the development of our epitaxial graphene on silicon carbide on silicon technology and some of its most promising applications. This platform allows to obtain any complex graphene -coated silicon carbide 3D nanostructures in a site – selective fashion at the wafer -scale and with sufficient adhesion for integration. Key capabilities for nano-optics and metasurfaces in the MIR are specifically unlocked by the graphene/silicon carbide combination. We have recently demonstrated that the sheet resistance of epitaxial graphene on 3C-SiC on silicon is comparable to that of epitaxial graphene on SiC wafers, despite substantially smaller grains. We also indicate that the control of the graphene interfaces, particularly when integrated, can be a more important factor than achieving large grain sizes. In addition, we show that well- engineered defects in graphene are preferable to defect -free graphene for most electrochemical applications, including biosensing. Promising examples of application of this technology in the More than Moore domain include integrated energy storage, MIR sensing and detection, and sensors for electro-encephalography.
Biography:
Francesca Iacopi received her MSc in Physics from Roma La Sapienza University, Italy (1996), her PhD in E.E./Materials Science from the Katholieke Universiteit Leuven, Belgium (2004), and she is currently Professor of Nanoelectronics, in the Faculty of Engineering and IT of the University of Technology Sydney, and Chief Investigator of the ARC Centre of Excellence in Transformative Meta-Optical Systems (TMOS). Iacopi has over 20 years’ R&D experience in semiconductor Industry and Academia. Her research focus is the translation of basic scientific advances in nanomaterials and novel device concepts into industrial processes. Her seminal work at IMEC on low-k dielectrics for on-chip interconnects over the 1999-2009 decade has informed the industrial uptake of porous dielectrics into modern semiconductor microprocessors. More recently, she invented a process to harness the properties of graphene on silicon for integrated micro-technologies. Major awards include a Gold Graduate Student Award from the Materials Research Society (2003), a Future Fellowship from the Australian Research Council (2012-2016), a Global Innovation Award (TechConnect, 2014) and was listed among the 30 most innovative Australian engineers in 2018. Prof. Iacopi is a Fellow of the Institute of Engineers Australia, serves in the Board of Governors of IEEE EDS (2021-23), as well as in various technical and strategic committees for IEEE and the Materials Research Society, and was selected as EDS Distinguished Lecturer in 2021.

New Applications of 2D Materials from Wearable Health to Memory Devices and 5G Switches
This talk will present our latest research adventures on 2D nanomaterials towards greater scientific understanding and advanced engineering applications. In particular, the talk will highlight our work on flexible electronics, zero-power devices, single-atom monolayer memory, non-volatile RF/5G/6G switches, and wearable tattoo sensors for mobile health. Non-volatile memory devices based on 2D materials are an application of defects and is a rapidly advancing field with rich physics that can be attributed to metal adsorption into vacancies. The memory devices can be used for neuromorphic computing and operate as switches up to 500GHz. Likewise, from a practical point, electronic tattoos based on graphene have ushered a new material platform that has highly desirable practical attributes including optical transparency, mechanical imperceptibility, and is the thinnest conductive electrode sensor that can be integrated on skin for physiological measurements including blood pressure monitoring with Class A performance. Much of these research achievements have been published in leading journals.
