Scientist / Postdoc (m/f/d)

for the topic:

Digital Workflow Ontologies and Machine Learning for Epitaxial Processes

- Internal Job Posting -

Epitaxial layers are the key functional parts in electronic and opto-electronic a BMFTR funded project digital twins will be developed for MOCVD processes and will be used for optimizing the process along the process chain up to the device including by means of machine learning. The industrial partner is AIXTRON one of the leading companies for MOCVD reactors.

The digital twin will be developed for the industry-established process of GaN layers and devices as well for Ga₂O₃ an emerging material of high interest for high-power applications.

Your tasks:

Defining the meta data space for the epitaxy of Ga₂O₃layers in an AIXTRON reactor
Generalizing the meta data for epitaxial processes of semiconductors with large band gap
Developing an ontology for the workflow
Developing machine learning exploiting the meta data of the processes

Meta data will be defined in the NOMAD Oasis framework.

Your requirements:

Completed academic study in physics chemistry mathematics or related fieldsat least a master degree
Knowledge in materials science
Experience with machine learning
Experience with NOMAD oasis would be beneficial
