Creating spin-polarized two-dimensional hole gases in nitride heterostructures 

Can high hole densities indeed induce room-temperature ferromagnetism in GaN?
This prediction, made by the p-d Zener model, has not been really tested due to the difficulty in achieving sufficiently high hole densities in GaN. In this project, the successful candidate will answer this scientifically intriguing and technologically significant question by utilizing polarization-induced two-dimensional hole gases formed in Mn-delta-doped nitride heterostructures.

These structures will be grown using molecular-beam epitaxy. Achieving ferromagnetism in such systems could significantly impact the development of multi-functional advanced devices on well-established nitride-based platforms.

This advancement will lead to new types of memory devices, logic circuits, and quantum computing elements with enhanced performance and new functionalities.

 

Your responsibilities

  • Growth of nitride heterostructures by molecular beam epitaxy
  • Sample characterization by x-ray diffractometry, atomic force microscopy, and magneto-transport and C-V measurements
  • Fabrication of gated-Hall bars
  • Band diagram simulation using 1D Poisson-Schrödinger solver
  • Data analysis and planning of experiments
  • Assisting in the preparation of proposals for external funding
  • Presentation of results at conferences and in publications

 

Your profile

  • PhD degree in condensed matter physics, electrical engineering, materials science, or a related field
  • Preferentially background in spintronics or device physics
  • Hands-on experience with nitride-MBE is advantageous

Position and salary

This position is available from October 01, 2024 and is limited to a 2-year period initially with excellent chance to be extended.

Salary and benefits are according to the Treaty for German public service (TVöD Bund) to a level of E13 (100%), taking work experience and special professional skills into account.
