PhD in Strain tuning of HTS thin films for clean energy

Information about the project
In cuprate High critical temperature superconductors (HTS) the superconductive phenomenon emerges from a metallic state, named “strange metal”, with properties that cannot be accounted for by conventional condensed matter theories. The highest superconductive temperature in HTS corresponds to the region of doping where the strange metal phase is most robust. It is believed that the route towards room temperature superconductivity goes through the understanding of the physics principles governing the strange metal phase, still unkown.

Our group has recently achieved research breakthroughs by using the strain induced by the substrate to tune the properties of the strange metal phase and of the superconductive state. The focus of the PHD position will be to go beyond conventional strain modification by patterning periodic nanostructures on the surface of the substrate. Nm thick films of HTS superconductors will be strongly affected by the superstructure which will change the ground state, possibly giving hints on how to increase the superconducting critical temperature towards room temperature.

Within this project, the student will lead this new experimental approach which will involve nanostructuring of substrates, thin film deposition and transport properties of nanoscale devices. We have a strong consortium consisting of expertise in superconducting materials (Chalmers), which can benefit from the theoretical support of various national (KTH, Uppsala, Chalmers) and international collaborations. The research is conducted at the Department of Microtechnology and Nanoscience – MC2. MC2 is a unique research department in the areas of micro- and nano-technology, housing more than 200 employees and PhD students. The research focus at MC2 is future nano- and quantum electronics, high speed electronics and photonics, and bio- and nano-systems.

All early-stage researchers recruited into the WISE program will be a part of the WISE Graduate School, an ambitious nationwide program of seminars, courses, research visits, and other activities to promote a strong multi-disciplinary and international network between PhD students, postdocs, researchers, and industry.

Major responsibilities
Your major responsibilities are to pursue your own doctoral studies. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing. The position generally also includes teaching on Chalmers' undergraduate level or performing other duties corresponding to 20 percent of working hours.

Qualifications
To qualify as a PhD student, you must have a master's level degree corresponding to at least 240 higher education credits with a strong background in Physics and Engineering.

Applicants should ideally have:
- Performed high-quality research in the area of nanoelectronics
- Experience in nanofabrication of electronic devices (cleanroom environment)
- Experience in growth of thin films/nanoribbons
- Experience in low-level electronic measurements at cryogenic temperatures
- Strong inner driving force and capabilities for independent work
- Excellent collaboration skills in a research team
- Potential to reach excellence in the research field

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.

The position requires sound verbal and written communication skills in English. If Swedish is not your native language, Chalmers offers Swedish courses.

Contract terms
Full-time temporary employment. The position is limited to a maximum of five years.

This recruitment is connected to the Wallenberg Initiative Materials Science for Sustainability (WISE). WISE, funded by the Knut and Alice Wallenberg Foundation, is the largest-ever investment in materials science in Sweden and will encompass major efforts at Sweden’s foremost universities over the course of 10 years. The vision is a sustainable future through materials science.
