The Greater Copenhagen Nanoscience Seminar
This seminar series is organized by the three nanoscience hubs located in the Copenhagen-Lund area. The aim is to to increase awareness about our mutual capabilities and to inspire collaborations.
Within a radius of just 25 km, the Copenhagen-Lund region features three strong hubs for nanoscience, with complementary strengths, scientific focus and capabilities:
- the Nano-Science Center at the University of Copenhagen
- NanoLund at Lund University
- a cluster of groups at the Technical University of Denmark
Each hub comprises more than 30 research groups from several disciplines and several hundred staff, has developed advanced facilities for synthesis, characterization and fabrication of nanostructures, has a strong track record in translating discoveries into new technologies, and each is heavily engaged in education at all levels.
Our joint vision is to discover, invent and develop nanosystems with functionalities that emerge from the designed interaction between highly controlled and tunable building blocks.
By combining highly controlled building blocks from very different material systems to realize advanced, functional systems, we aim to jointly address challenges that are out of reach for an individual center.
The aim of this seminar series is to increase awareness about our mutual capabilities and to inspire collaborations.
Scheduled talks: once a month on a Friday at 15:15
Next seminars: 18th June, and 24th September.
18th June 2021: Jesper Nygård (KU): Still going strong - Old nanowires, new tricks
Semiconductor nanowires were pioneered in Lund 20 years back. During the past decades these nanomaterials have been implemented in several branches of physics, photonics, bioscience and nanotechnology. I will give a few key examples from the research on quantum devices in Copenhagen; hybrid quantum dot systems, superconducting devices and units for quantum computing/simulations . In the second part, I will present some of the new nanowire-based structures that were developed for these experiments, e.g. double-wires, kinks, superconducting core-shell structures, shadow junctions, and cross sections [2-4]. Hopefully, that this can lead to a joint discussion on how some of these advances in materials science and nanofabrication might find applications also outside the field of quantum devices. The talk will be 30 minutes followed directly by this discussion.

Short Bio: Jesper Nygård, Professor, Center for Quantum Devices & Nano-Science Center, Niels Bohr Institute, University of Copenhagen
Jesper Nygård is a professor of condensed matter physics at the Niels Bohr Institute. He holds a PhD in experimental physics (2000) and has worked at CNRS (France), Harvard and Berkeley University (US). His research has focused on electron transport in low-dimensional semiconductors, superconductors and nanostructures, bridging the areas of materials science and quantum devices. For the past decade his group has developed novel devices based on semiconductor nanowires. He is co-founder of the Center for Quantum Devices (qdev.dk) and former head of the Nano-Science Center, Copenhagen.
In order to achieve effective cross-fertilization, we will test a seminar format of two parts, where the first consists of 30 min lecture and 15 min questions and the second a 30 min “collaboration-space” where you are invited to stay on in Zoom for discussing ideas and possible collaborations. The total time for the event is between 75 and 90 minutes, depending on the topic and the arrangement with the speaker.
The Zoom link will be e-mail to all members of the three research environments. in case you are interested and have not received the link, please contact: Gerda [dot] Rentschler [at] ftf [dot] lth [dot] se
