The Leibniz Institute for Crystal Growth (IKZ) is a leading research institution in the field of science & technology as well as service & transfer of crystalline materials. Our goal is to enable solutions for pressing societal challenges (e.g. communication, artificial intelligence, climate protection, health, etc.) through modern electronic & photonic technologies. The work covers the entire spectrum from basic and applied research to pre-industrial development and is carried out in cooperation with national and international partners from universities, academies and industry. The institute is part of the Forschungsverbund Berlin (https://www.fv-berlin.de/) and a member of the Leibniz Association (https://www.leibniz-gemeinschaft.de).

The Leibniz-Institut für Kritallzüchtung currently looking for a

Student assistant (f/m/d)

with the possibility of a subsequent Master's thesis on the subject:

 

Electro- and Photoluminescence Studies of UV LED Degradation.

We are seeking a highly motivated Master's student to join our research team for a thesis project focused on electroluminescence and photoluminescence studies of UV LED degradation. This position offers an exciting opportunity to work on cutting-edge optoelectronic light emitting diodes operating in the UV including device reliability analysis.

The efficiency and longevity of ultraviolet (UV) light-emitting diodes (LEDs) are critical for applications in sterilization, water purification, and sensing technologies. However, performance degradation over time remains a significant challenge in this field. This project aims to investigate the degradation mechanisms of UV LEDs mainly through detailed electroluminescence (EL) and photoluminescence (PL) spectroscopy, identifying key factors affecting their stability and efficiency.

Responsibilities

  • Conduct in-situ electroluminescence and photoluminescence measurements on UV LEDs while aging in a home-built setup.
  • Analyze emission spectra and identify degradation trends.
  • Correlate optical properties with electrical and structural changes.
  • Working with a multidisciplinary team to help interpret experimental data.
  • Contribute to research publications.

Requirements

  • Bachelor's degree in Physics, Electrical Engineering, Materials Science, or a related field.
  • Programming skills, ideally Python.
  • Knowledge of semiconductor optoelectronics and solid-state physics.
  • Experience with optical spectroscopy techniques is an advantage.
  • Strong analytical skills and ability to work independently.
  • Interest in experimental research.

What We Offer

  • Hands-on experience with state-of-the-art spectroscopic techniques.
  • Opportunity to contribute to impactful research in UV LED technology.
  • Collaboration within an interdisciplinary research team.
  • Access to advanced laboratory facilities and mentorship from experts.
  • Possibility of publishing research findings in scientific journals.
  • 8 hours per week (by arrangement) a 13,69 €.
