| Mohammad SAMIZADEH NIKOONanyang Technological University, Singapore Mohammad Samizadeh Nikoo is a Nanyang Assistant Professor in the School of Electrical and Electronic Engineering (EEE) at Nanyang Technological University (NTU), Singapore. He is the founding director of the Innovative Electronic & Electromagnetic Device Laboratory (i–Lab). He received his PhD from EPFL, Switzerland, in 2022. In the same year, he joined the Integrated Systems Laboratory at ETH Zurich as a research scientist, before beginning his tenure-track appointment at NTU in 2023. Dr. Samizadeh Nikoo is a Fellow of the National Research Foundation, Singapore (Class of 2024). He has received several distinctions and awards and currently serves as the lead principal investigator (PI) on multiple national research projects. His research focuses on developing a new generation of high-frequency semiconductor components for future information technologies. Speech Title: High-Performance Electronic Metadevices for Millimeter-Wave and Terahertz Integrated Circuits Abstract: Approaching the terahertz band from the electronics side is of great technological importance, with the promise of advancing next-generation wireless communication systems toward 6G and beyond. However, inherent limitations of high-speed transistors, the primary building blocks of monolithically integrated high-frequency circuits, have hindered the realization of high-performance terahertz electronics. Electrical metastructures offer an alternative paradigm, in which modulation of the conductivity of a semiconducting layer controls collective quasi-electrostatic responses within a lumped structure, enabling electronic functionalities such as switching, mixing, and parametric amplification. Compared with conventional transistors, electrical metastructures enable ultra-low contact resistances, leading to record-high switching cutoff frequencies well beyond 10 THz in a compact device platform, referred to as electronic metadevices. The first part of this talk highlights recent advances in III-nitride electronic metadevices operating up to 1 THz and introduces a new generation based on quasi-one-dimensional electrical metastructures with enhanced electrical performance. We present theoretical insights into the collective responses governing the operation of electronic metadevices and elucidate their ultimate performance limits. In the second part, we introduce a metastructure-based paradigm for directly realizing high-performance millimeter-wave and terahertz components with ultracompact footprints, demonstrated the compatibility of metatronic devices with commercial silicon processes. |
| Eleni MAKARONAInstitute of Nanoscience and Nanotechnology, NCSR “Demokritos”, Greece Dr. Eleni Makarona is Director of Research at the Institute of Nanoscience and Nanotechnology, NCSR "Demokritos", Greece. She holds a PhD in Physics from Brown University (USA), where she trained under Prof. Arto V. Nurmikko on III-nitride optoelectronics, supported by a competitive graduate fellowship awarded to the top 10% of international applicants. Her research spans two parallel axes maintained continuously for nearly two decades: silicon photonic biosensors, and chemically synthesized metal oxide nanostructures. Her work on photonic sensors spans applications in biodiagnostics, food safety and quality assurance, and environmental monitoring. Moreover, she is co-inventor of the Broadband Mach-Zehnder Interferometer and Broadband Young Interferometer detection architectures — novel sensing principles that progressed from fundamental invention through patents to international prototype deployment. In metal oxide nanostructures, her work follows a material-first philosophy in which device concepts emerge from deep understanding of defect-driven mechanisms, spanning optoelectronics, sensing, energy harvesting, and hardware security. She has led or coordinated competitive research programs across European and national frameworks, and has delivered invited presentations at international conferences. She was awarded the Greek L'Oréal–UNESCO Award For Young Women in Science in 2010. Speech Title: Scalable Functional Devices Based on Chemically Synthesized ZnO Nanostructures: Bridging Synthesis and Device Functionality Abstract: Low-cost, chemically synthesized metal oxide nanostructures offer a compelling pathway toward scalable, cost-efficient, and sustainable electronic and sensing devices. However, building functional devices from such nanostructures requires more than mastering fabrication and compatibility with standard micro/nanofabrication processes — it demands a deeper understanding of the underlying physical mechanisms governing the material itself and of how these translate into, and ultimately dictate, device performance. This talk presents a device-oriented framework in which zinc oxide (ZnO) serves as a representative material platform. Central to this framework is the systematic investigation of defect-driven mechanisms emerging from the growth environment — mechanisms that, contrary to conventional device design assumptions, are shown to be the dominant determinants of functional behavior rather than structural geometry or intentional doping alone. This perspective enables the development of functional systems across diverse application domains. Representative implementations span ZnO-based homojunction devices, sensing platforms exploiting defect-mediated mechanisms, energy harvesting systems, and hardware security elements. Collectively, these demonstrate a coherent, fabrication-compatible, and scalable pathway for functional device realization from chemically synthesized nanostructures — one that redefines material imperfection not as a limitation to be suppressed, but as a design parameter to be understood, controlled, and exploited. |
