Join a cutting-edge project focused on advancing Electron Spin Resonance (ESR) technology! ESR is a powerful tool for studying materials with unpaired electrons, revealing critical insights in chemistry, biology, physics, nanosciences, and quantum mechanics. However, current commercial spectrometers require large sample sizes due to limited sensitivity, hindering small-scale research. Our project plan to harness the recent breakthroughs of the superconducting quantum technologies at 10mK and extend them to a wider temperature range. We aim to develop an ESR spectrometer using high critical-temperature superconductor (HTS) microwave resonators. These HTS resonators promise to enhance spin sensitivity up to liquid nitrogen temperature, by bridging and thus overcoming the limitations of existing technologies. As an intern, you’ll engage in designing, fabricating, and characterizing traditional metallic resonators, and later apply your expertise to HTS resonators. You’ll measure their microwave responses under cryogenic conditions (down to ~6K) and benchmark their performance against traditional resonators. Your work will push the boundaries of spin sensitivity, opening doors to studying innovative small-scale samples. This hands-on experience will immerse you in the exciting realms of microwaves, superconducting technologies, quantum devices, and spin materials, potentially leading to publication and a financed PhD in this pioneering field.
