The Leibniz-Institute for Crystal Growth (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 ( and a member of the Leibniz Association You can find more details on the institute webpage:

We are offering a

PhD Student position (m/f/d)

for the topic:

“In-situ calorimetry in the transmission electron microscope”

The Leibniz Institut für Kristallzüchtung recently has a strong focused activity to develop novel  oxides for power electronic applications that can outperform  known materials such as SiC and GaN. The System (SiGeSn)O2 is a hot candidate since it holds the promise to allow for p-type doping, which is rare in oxide semiconductors. Understanding the phase diagram of this materials system is a prerequisite to realize epitaxial layer and heterostructures. The goal of the present project is to develop in-situ calorimetry in the transmission electron microscope to gain quantitative insights into the mechanisms of phase formation and phase transition at the atomic scale by in-situ transmission electron microscopy. IKZ has excellent expertise and facilities in this field, among them an aberration corrected TEM/STEM with fast camera and in-situ holders for heating and biasing. The task of the PhD includes the TEM studies, image simulations and modelling. Collecting and evaluating in-situ data is of particular importance here.

The PhD project is performed in the framework of a joint project of IKZ with two Paul-Drude-Institut, where materials growth is done and Ferdinand-Braun-Institut, where devices are realized. The project is part of the Leibniz Science Campus GraFox “Growth and fundamentals of oxides for electronic applications”, which seizes to fuse the excellent individual activities and competences in Berlin. Details can be found on The project will benefit from IKZs participation in FAIRmat, a consortium that aims at establishing a comprehensive and interdisciplinary data infrastructure in materials science (
