Postdoc position on Ultra-low-noise HEMT amplifiers

4 days ago


Gothenburg, Sweden Chalmers tekniska högskola Full time

at Chalmers University of Technology explores electronics for very low noise and very high frequencies. During academic year 24/25, we have an open position for a postdoctoral fellow for exploring HEMT technologies in ultra low-noise amplifiers. The applications are found in quantum computing and mm-wave instrumentation.

In recent years, we have advanced state of the art for the InGaAs HEMT transistor and the low-noise amplifier both with respect to noise and dc power dissipation. We are fabricating own devices in a state-of-the-art HEMT process and have advanced characterization labs. Together with our industrial partner, a full MMIC process and cryogenic industrial testing are available.

Project description The postdoc position is focused on experimental work in advancing low-noise InGaAs HEMTs for cryogenic applications 1-100 GHz. Depending on the background of the applicant, the research can be focused on device physics and engineering or the full HEMT LNA. We have international collaborations with US and South Korea and participates in the EU Chips JU project Move2THz for exploring InP HEMTs on silicon bulk.

Major responsibilities
Your major responsibility as postdoc is to perform your own research in a research group. The position may also include supervising master's and/or PhD students to a certain extent. Another important aspect involves collaboration within academia and with society at large. The position is meritorious for future research duties within academia as well as industry/the public sector.

Qualifications
Applicants should have (or planning) a Ph.D. degree in (compound) semiconductor electronic devices and/or microwave engineering. The position can be started during academic year 24/25 and is a full-time employment.

To qualify for the position of postdoc, you must hold a doctoral degree awarded no more than three years prior to the application deadline (according to the current agreement with the Swedish Agency for Government Employers). Exceptions from the 3-year limit can be made for longer periods resulting from parental leave, sick leave or military service*.

The position requires sound verbal and written communication skills in English. Swedish is not a requirement but Chalmers offers Swedish courses.

You are expected to be somewhat accustomed to teaching, and to demonstrate good potential within research and education.

* The date shown in your doctoral degree certificate is the date we use, as this is the date you have met all requirements for the doctoral degree.

Contract terms
This postdoc position is a full-time temporary employment for twoyears.
We offer Chalmers offers a cultivating and inspiring working environment in the coastal city of .
