PhD student position in Thermal management in next generation of highly integrated RF front-ends


The Department of Microtechnology and Nanoscience focuses on research, innovation and education within the fields of future electronics, photonics, bio- and nanosystems. A close collaboration with Swedish and international partners within academia, industry and society enables scientific excellence and creates an innovative environment. In addition to the 200 researchers and PhD students, MC2 houses a cleanroom for micro- and nanofabrication with the latest equipment.

Information about the Microwave Electronics Laboratory (MEL)

The Microwave Electronics Laboratory (MEL) at the Department of Microtechnology and Nanoscience emplys more than 40 people performing world-class research on high speed electronic components, circuits, and systems for a wide range of communication and sensing applications in the frequency range from 1 GHz to 500 GHz and beyond. Our facilities include a uniquely well-equipped laboratory for advanced millimeter wave measurements and a state-of-the art cleanroom facility.

There is an increasing demand in society for more capacity in the mobile network, as well as smaller and multi functional sensors. This for applications such as autnomous cars, low latency communication for medical applications, as well as security. Next generation of highly integrated mm‐wave frontends for communication and sensors could potentially be designed using the semiconductor technology GaN. The move to higher frequencies for some applications could also make is beneficial to integrate more than one transmitter/receiver per die, hence the circuits will couple both electrically as well as thermally on the chip. The on‐chip thermal management will therefore be increasingly important, and optimization of it needed for certain applications.

In recent years, electronic devices and circuits based on wide bandgap semiconductors such as SiC and III-nitrides (GaN) have demonstrated disruptive performance in terms of frequency, power, and efficiency figure of merits. We now investigate advanced device concepts to further harvest the potential of III-nitride devices and circxuits.

Major responsibilities

This PhD-student position will focus on research on III-nitride devices and circuits for new communication and sensor systems. The student will explore new cooling concepts as well as material compositions to optimize the die-level thermal properties to improve high frequency operation, output power, linearity, and efficiency. The goal is to push the limits of III-nitride semiconductor devices. The research will therefore include a wide range of activities such as advanced characterization, modeling and simulations. The PhD-student will perform extensive experimental and theoretical investigations to understand the fundamental and practical limits of the electrical as well asl thermal properties of electronics based on III-nitride semiconductors.

The PhD-student will be a member in a team of other PhD students and senior researchers, both from industry and academia, working with semiconductor technology development, circuit design, and realization of complete wireless system demonstrators. The PhD student will mainly perform research combined with some teaching and collaborative activities with partners. A PhD student position at Chalmers commonly consists of 4 years of research and courses plus 1 year of departmental work (teaching, external projects etc.)

Position summary

Full-time temporary employment. The position is limited to a maximum of five years.


To qualify, you should hold a MSc degree in physics or electrical engineering (or equivalent), generally not older than two years. Experiences in device characterization and thermal simulations are meritorious.

Important qualities are enthusiasm, to be able to drive and conclude projects independently, take own initiatives and discuss/develop own ideas, be creative and have a problem-solving mindset. The project is in collaboration with other researchers and industry. Therefore, excellent cooperation and social abilities are important.

The position requires sound verbal and written communication skills in English.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
