PhD Position - Spin-Orbit entangled states in complex oxide thin films

Jülich Research Centre (FZJ)

Jülich, Germany

Work group:

PGI-7 – Elektronische Materialien

Area of research:

PHD Thesis

Job description:

The Peter Grünberg Institute (PGI) is the central platform for basic research in the field of nanoelectronics and combines cutting-edge research, technology development and innovative device concepts. Our strong basic research in solid state physics and materials science paves ground for the discovery and use of novel electronic phenomena, methods, and materials. At Electronic Materials Department (PGI-7), our research focuses on the fabrication of oxide thin films and nanoelectronic devices for novel computing paradigms such as neuromorphic computing. At Quantum Theorie of Materials Department (PGI-1), we calculate and analyze theoretically the complex structural, electronic and magnetic quantities of solids and molecules – for fundamental research and practical applications.

Your Job:

The PGI-7 and PGI-1 are offering an interdisciplinary PhD position, combining theory and experiments on spin-orbit entangled states in oxides. The chosen materials such as iridates will be grown and characterized within the Electronic Oxide Cluster tool (EOC), models for their description will be set up in conjunction with first-principles calculations. In this PhD project, we will in particular address the role of defects in materials close to the quantum spin-liquid state and elucidate possible ways to engineer their functional properties by certain defect arrangements. Your tasks in detail:

  • Synthesis of tailored epitaxial thin films and heterostructures with atomic precision

  • In situ characterization within the Electronic Oxide Cluster (EOC) tool

  • Characterization of low temperature transport and magnetisms

  • Advanced spectroscopy at different synchrotron facilities (e.g. BESSY, ELETTRA)

  • Analyzing and optimizing structural, electronic and magnetic material properties through model Hamiltonians and DFT calculations

  • Programming small computer codes (or routines to be included in the existing codes) needed for the theoretical analysis of the obtained results

  • Presentation, communication, and publication of cutting-edge research in international environment

Your Profile:

  • Excellent University degree in physics or material science
  • Profound knowledge in Solid State Physics
  • Experience in either experimental or theoretical solid state physics
  • Interdisciplinary and cross-topical thinking
  • Team-minded, self-reliant, and highly motivated character
  • Good communicational skills in English (German in addition will be preferred)

Our Offer:

  • At PGI, we offer a world-leading, interdisciplinary and international research environment, provided with state-of-the-art experimental equipment and versatile opportunities to grow as a curious researcher.
  • A highly motivated group as well as an international and interdisciplinary working environment at one of Europe`s largest research establishments
  • Chance of participating in (international) conferences and project meetings
  • Continuous, professional support by your scientific supervisor
  • Further development of your personal strengths, e.g. via a comprehensive further training programme
  • Pay in line with 75 % of pay group 13 of the Collective Agreement for the Public Service (TVöD-Bund)
  • Usually a contract for the duration of 3 years
