About the project

Superconductivity is a macroscopic quantum phenomenon with outstanding properties and impact in many applications. Since high temperature superconducting (HTS) cuprate materials were discovered 30 years ago, they had to face unknown science and new materials engineering complexities [1].

HTS are strongly correlated systems, showing unconventional superconductivity and their microscopic theory is still unidentified. In addition, they need to be doped to be superconductors and exhibit novel vortex phases. Disorder is a strong enemy for the superconducting state of HTS, but if properly designed, it can be used as an outstanding source for vortex pinning, as we showed in [2,3].

Beyond the still unsolved questions about HTS, nowadays, the international community is able to fabricate HTS tapes for high current energy efficient applications (high power cables, wind generators, electrical aviation) and large scale infrastructures (fusion, circular colliders, NMR beyond 1 GHz), one of the remaining issues being the need to reduce the cost/performance ratio of the fabrication process. We have developed a novel high throughput process, called Transient Liquid Assisted Growth (TLAG) process [4], which is able to grow epitaxial superconducting films at 100 times faster than standard methods [5] with high performances, and therefore overcoming the market obstacles.

The PhD project is addressed towards the understanding of the TLAG growth mechanisms, tuning of material microstructure to boost the superconducting properties and understanding of vortex physics in TLAG films. Advanced growth facilities (including in-situ XRD synchrotron), last generation Transmission Electron Microscopes and ultrahigh magnetic field installations 16T at cryogenic temperatures will be available for this project.

Job positions description

The project aims to engage talent young students for a Materials Science doctorate in the field of High Temperature Superconductors (HTS), by investigating the novel high-throughput TLAG growth process. They will be integrated in a large interdisciplinary and international group, with different background expertise in the field of HTS materials developing cutting-edge research in the synthesis, microstructural and physical understanding of high temperature superconductors. The goal is to unravel the growth mechanisms of TLAG and boost the superconducting properties at high magnetic fields by designing the material microstructure landscape. This research was initiated with an ERC-Advanced Grant which was followed by two ERC-Proof-of-Concepts.

Requirements

We offer 3 positions with the following requirements:

  • Bachelor and master in material science, physics, chemistry, chemical engineering, nanoscience or related fields.
  • Good knowledge in Condensed Matter Physics, nanomaterials or metal-organic synthesis.
  • A high level of English. All working meeting are held in English.
  • High motivation to experimental research.
  • Working aptitudes in a collaborative group.

What do we offer

ICMAB Institute offers excellent conditions for PhD students, including:

  • a creative, world-class interdisciplinary research environment for fundamental and applied nanoscience state-of-the-art infrastructure for the preparation and characterization of nanostructured materials.
  • a highly regarded scientific education.
  • a strong international nanoscience network.
  • Experience and knowledge on superconductivity, superconducting materials and electron microscopy characterization techniques will be valuable.
  • The PhD will be integrated in a very international group of PhD students and Postdocs with backgrounds in chemistry, materials science and physics of superconducting materials.

About the SUMAN group

Superconducting Materials and Large Scale Nanostructures, SUMAN department has been active in the field of superconducting materials since the discovery of High Temperature superconductors, more than 20 years ago, it has widely contributed to the field of vortex pinning analysis and materials development for more than 15 years and more recently, since about ten years, it has shifted its interests towards the chemical solution approaches to superconducting thin films and coated conductors, due to its high potential in terms of cost-effectiveness for practical applications. [Continue reading]
