Leibniz Institute for Crystal Growth (IKZ), Berlin

The Leibniz-Institut für Kristallzüchtung (IKZ) is a leading research institution in the area of science & technology as well as service & transfer of crystalline materials. Our goal is to enable solutions for urgent societal challenges (e.g. communication, artificial intelligence, climate protection, health etc.). by modern electronic & photonic technologies. The work covers the full spectrum from basic over applied research up to pre-industrial development and is performed in collaboration with national and international partners from university, academy and industry. The institute is part of the Forschungsverbund Berlin (https://www.fv-berlin.de/) and the Leibniz Association www.leibniz-gemeinschaft.de. You can find more details on the institute webpage: www.ikz-berlin.de.

The Section Fundamental Description at the Leibniz-Institut für Kristallzüchtung is looking for a

PhD Student (m/f/d)

for the topic:

"Kinetic Monte Carlo Simulations for the Homoepitaxy of Ga₂O₃”

Ga₂O₃ is a highly promising candidate for high-power electronics and IKZ is developing processes for industrial scale. This requires also fundamental investigations of the growth kinetics.

Within the BMFTR project Epi-Techno-Digital with total six partners one goal is the optimization of the MOCVD process of Ga₂O₃ layers. The process will be developed for a recently installed AIXTRON showerhead reactor and will be supported by developing a digital twin, employing machine learning and numerical computations of atomistic processes.

At IKZ, a kinetic Monte Carlo tool has been developed in the programming language julia. This allows a very flexible use and extension. In particular, the work covers

• developing an appropriate model to represent the main possible processes at the surface in close cooperation with the SOLgroup at the Humboldt-Universität zu Berlin, where DFT calculations will be performed.
• running simulations and compare them to experimental results in close cooperation with the experimental group at IKZ.
• applying machine learning tools on the experimental and numerical data.

Requirements

• Master degree in physics, chemistry, mathematics or related fields
• Knowledge in materials science
• Knowledge of python
• good English language skills to work in an international environment

What we offer

The position is funded by the Federal Ministry of Research, Technology and Space (BMFTR) and is limited to three years. 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).
