The Leibniz-Institut für Kristallzüchtung (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). You can find more details on the institute webpage: https://www.ikz-berlin.de. 

Commencing as soon as possible there is an opening for a 

 

PhD position (f/m/d)

for the topic:

“Growth and characterization of homoepitaxial gallium oxide films”

The development of innovative solutions for efficient power electronics plays a crucial role in connection with the energy transition. The novel semiconductor material gallium oxide (β-Ga2O3) has the potential for low-loss and cost-effective power electronics and could therefore make a decisive contribution to such a solution. However, a clear consensus on the optimum surface orientation for lateral power devices has not been reached so far. Therefore our recently granted DFG project aims to provide a comparative studies of devices on different substrate orientations. The main aspects of the project are distributed over bulk and thin film growth (IKZ/Berlin), device processing (FBH/Berlin) and device characterization/testing (TUB/Berlin). The advertised position deals with the homoepitaxial growth of β-Ga2O3 by MOVPE with the goal to develop a process to produce high-quality β-Ga2O3 layer structures with optimized interface properties and homogeneous thickness and doping concentration on (100) and/or (010) β-Ga2O3 semi-insulating wafers. This work package thus represents the link between bulk crystal growth and device processing.

Applicants Responsibilities:

  •       epitaxial growth of β-Ga2O3 by MOVPE on differently oriented substrates
  •          development of growth models
  •          process-accompanying standard characterization (e.g. AFM, Ellipsometry, XRD)
  •          wet chemical substrate pre-treatment

Applicants should have:

  •           a MSc degree or a Diploma in physics, chemistry, materials science or a related discipline
  •           expertise in the field of oxides, thin film growth and thin film characterization
  •           the capability to scientifically work on an independent basis; carry out structured scientific work within a highly motivated team of researchers and technicians
  •           good English language skills to work in an international environment.  

What we offer

The position is limited to three years, an extension for another year is possible. Payment is according to TVöD Bund (E13 75%) (Collective agreement for the public sector). The contract includes the usual social benefits (30 vacation days in a 5-day week, flexible working hours). The Leibniz-Institut für Kristallzüchtung actively promotes the development of young scientists and follows the guidelines of the Leibniz Association.

 

The Leibniz-Institut für Kristallzüchtung actively supports a healthy work-life balance and is an equal opportunities employer. Female candidates are encouraged to apply and will be given preference if suitably qualified. Among equally qualified candidates, preference will be given to candidates with disabilities. IKZ promotes diversity. We welcome every qualified application, regardless of age, belief, disabilities, ethnic origin, gender, nationality, religion, or sexual orientation.
