Description du poste
The Fraunhofer-Gesellschaft (www.fraunhofer.com) is one of the world's leading organizations for application-oriented research. 74 institutes develop pioneering technologies for our economy and society – more precisely: 30 000 people from technology, science, administration and IT. They know: Anyone who comes to Fraunhofer wants to and can make a difference. For themselves, for us and for the markets of today and tomorrow.
**INNOVATIONS FROM A SINGLE SOURCE**
CHANGE STARTS WITH US
At the Fraunhofer Institute for Applied Solid State Physics IAF we know our technologies like the back of our hand. Because we are one of the few scientific institutions worldwide to conduct research along the entire semiconductor value chain and on tailor-made synthetic diamonds. Whether high-frequency circuits for communications technology, voltage converter modules for electromobility, laser systems for measurement processes, or innovative hardware and software for quantum computers and quantum sensors: we develop tomorrow’s technology in-house for a sustainable and secure society.
How can GaN-based transistors for high-frequency applications be made more reliable? In your PhD research, you’ll get to the bottom of this question: You’ll investigate degradation mechanisms and develop approaches to specifically improve the devices. In doing so, you’ll work closely with colleagues from the fields of technology, epitaxy, and measurement technology.
**Be part of change**
* You’ll conduct reliability tests, analyze degraded devices, and actively contribute to identifying physical failure mechanisms.
* Using simulations, you will optimize the devices and develop them further in a targeted manner.
* You will develop robust methods for electrical characterization and reliability assessment.
* Planning, conducting, and monitoring technology experiments for the fabrication of GaN HEMTs with improved reliability is also part of your responsibilities.
**What you contribute**
* A master’s degree in electrical engineering, microsystems engineering, physics, or a related field, as well as, ideally, knowledge of solid-state and semiconductor physics.
* A passion for experimental research, an interest in analysis and simulation, and some experience in programming and data analysis.
* An independent, structured, and scientific approach to work; the ability to quickly familiarize yourself with new research questions; and strong teamwork and communication skills.
* Very good German and good English skills for working in an international environment.
**What we offer**
* State-of-the-art research infrastructure with unique facilities spanning the entire value chain
* Opportunities for specialization and interdisciplinary work through a wide range of research areas
* Ongoing participation in current research discourse and freedom in conducting one’s own research
* Collaboration with colleagues within the Fraunhofer Society as well as with other scientific institutions a
