Postdoctoral Researcher in Quantum Circuits: Detectors using Topological Materials

Aalto University

An experimental postdoctoral position in the field of superconducting hybrid detectors using topological materials is available in the NANO group, Department of Applied Physics at Aalto University, Finland. We are leading research in the field of quantum circuits and superconducting hybrid devices based on novel materials, including two-dimensional van der Waals materials. These hybrid circuits form a promising direction within the emerging field of quantum technologies, which enables among others supersensitive sensors for detection flux, charge, phonons at the sensitivity limits governed by quantum mechanics. This field of research has made tremendous progress during recent years, and presently offers plenty of exciting opportunities for young scientists, in both academia and industry.
This position is part of the Academy of Finland’s programme RADDESS (Radiation Detectors for Health, Safety and Security). The goal is to develop ultrasensitive detectors based on novel carbon materials in superconducting hybrid structures. Recently, we have developed supeconducting carbon nanotube devices which display record-high supercurrents for their size. Such carbon nanotubes, or their superconducting 2D-material counterparts, will be employed as ultrasensitive bolometers. This work is a collaborative effort where the partner groups are the QCD group of Prof. Mikko Möttönen (Aalto University) and the Terahertz group of Dr. Visa Vesterinen (VTT Technical Research Centre of Finland Ltd). This work parallels the efforts in Academy of Finland’s Center of Excellence “QTF”, Quantum Technology Finland, the synergy of which will speed up progress and offer complementary solutions.
As a postdoctoral researcher, you will design, fabricate and characterize your own devices using in-house state-of-art micro and nano-fabrication. The electrical measurement will be performed down to 10mK and, when needed, in magnetic fields as high as 14T. You will be involved in quantum detection experiments at microwave frequencies, which will be carried out using state of the art techniques, including Josephson parametric amplifiers. You will also be involved in the programme of European Microkelvin Platform (, 2019-2022), within which various nanodetector projects are ongoing.
We are looking for a bright, motivated researcher to join our team. We expect you to have an excellent research record in solid-state physics or related disciplines during your PhD work and during your earlier postdoctoral appointments if any. Prior laboratory experience in the fields of mesoscopic physics, nanoelectronics, cryogenics, microwave electronics, circuit design, clean-room techniques, and instrument programming is a plus.
Our research group is a member of the Academy of Finland’s Center of Excellence “QTF”, Quantum Technology Finland. The work takes place in Low Temperature Laboratory and Micronova nanofabrication center, which are part of the national OtaNano research infrastructure. The group is also part of the Centre for Quantum Engineering at Aalto University
The starting salary of a postdoctoral researcher is 3620 €/month (gross), and it increases as you progress in your research and prove your excellence. Following the standard practice in the Department of Applied Physics, the contract will be made initially for two years, with a possible extension of 1-3 years depending on your performance.
The position is funded by the Academy of Finland under RADDESS programme.
