Scientific Member of Staff / PhD Student (m/f/d) - Gallium Oxide for Power Electronics

The Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH) is an application-oriented research institute in the fields of high-frequency electronics, photonics and quantum physics. It researches electronic and optical components, modules and systems based on compound semiconductors. These devices are key enablers that address the needs of today’s society in fields like communications, energy, health, and mobility. It covers the entire value chain from design to ready-for-delivery systems.

In our Wide-Bandgap Electronics Department we evaluate new semiconductor materials and transistor devices towards their potential for power electronic switching applications. In this context, we are looking for a

Scientific Employee (m/f/d),

to start as soon as possible.

Reference number 22/26

Your tasks

• Design and fabrication of lateral gallium oxide-based switching transistors for fast-switching and efficient power converters
• Fabrication of the devices on the FBH semiconductor process line and static and dynamic measurements of their electrical characteristics
• Publication of the results in scientific journals and presentation at conferences
• Use the results for your PhD thesis

Your profile

• A master’s degree or equivalent in electrical engineering, physics, or a related field
• Knowledge or experience in the field of semiconductor devices as well as in power electronics is required
• Initial experience with the processing and electrical characterization of electronic semiconductor devices is advantageous
• You are scientifically motivated by an interdisciplinary topic that encompasses aspects of power electronics, high-frequency electronics, and new semiconductor materials beyond Si, SiC, and GaN.
• You are dedicated, work meticulously and independently, and have a very good command of written and spoken English. Suitability for working in cleanrooms is required.

Our offer

• A versatile position at a leading research institute
• A workplace with ideal public transportation connections, employer subsidy for a job ticket, and bicycle parking spaces
