PhD Scholarship Position in Next Generation Iii-nitride Millimeterwave Devices and Integrated Circuits

Chalmers University of Technology is pleased to invite applicants to apply for a PhD position in nanotechnology. Successful candidate will have funding to work and study for 4 years in Sweden. The deadline for applying is January 10, 2019.

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 division

The Microwave Electronics Laboratory (MEL) at the Department of Microtechnology and Nanoscience employs 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.

A major part our research is targeting new semiconductor materials and devices to enable higher capacity and improved energy efficiency in a wide range of future microwave and millimeter systems. 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 circuits.

Major responsibilities

This PhD-student position will focus on research on III-nitride devices and circuits. We will explore new concepts in material and device processing to optimize different important properties, such as high frequency operation, output power, linearity, and efficiency, of importance in high frequency systems. The goal is to push the limits of III-nitride semiconductor devices. New epitaxial designs will be grown by our collaborative partners and HEMTs will processed as well as characterized and evaluated by us at Chalmers. The goal to optimize high frequency performance will involve aggressive lateral and vertical down-scaling of important transistor features.

The research will therefore include a wide range of activities such as epitaxial design, device processing, and characterization. The PhD-student will perform extensive experimental and theoretical investigations to understand the fundamental and practical limits of high frequency electronics based on III-nitride semiconductors. The PhD-student will use our advanced device processing and advanced characterization facilities to connect theoretical predictions with experimental verification.

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.

Full-time temporary employment. 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.)


To qualify, you should hold a MSc degree in physics or electrical engineering (or equivalent), generally not older than two years. Experiences in semiconductor processing in cleanrooms and device characterization are meritorious. Well-documented capability of communicating in English, both spoken and written, are required.

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.

Chalmers offers a cultivating and inspiring working environment in the dynamic city ofGothenburg.
