PhD student positions in Semiconductor devices for future terahertz electronics

4 weeks ago


Gothenburg, Sweden Chalmers tekniska högskola Full time

We are looking for two highly motivated and skilled PhD students to join our team and contribute to our exciting research in terahertz electronics. In this project, you will investigate cutting-edge semiconductor devices and circuits for future high-frequency electronics. Moreover, as part of a European project and an industry competence centre, you will collaborate with key actors in the field, from both industry and academia.

Project description The PhD positions are related but with an individual focus on two different types of semiconductor devices. One doctoral thesis aims to demonstrate the first indium phosphide-based cryogenic amplifier on silicon. In this first European Chips Act project at Chalmers, you will closely collaborate with the Swedish company Low Noise Factory AB, world's leading industrial producer of cryogenic low-noise amplifiers, and the key European actors in the field in Europe. The other doctoral thesis aims to explore new receiver architectures for submillimetre wave applications using low-noise semiconductor diode mixers. This project is part of the Wireless Infrastructure Technology Centre at Chalmers (), and you will closely collaborate with Swedish industry and the American company Virginia Diodes, Inc., a world leader producer of millimetre wave and terahertz devices, components and systems.

Information about the division and the department
is a unique research environment in micro- and nanotechnology, housing more than 250 researchers and PhD students. At the , our main research activities are new materials, devices and circuits for applications ranging from basic science to future sensors and communication systems (6G). We are at the forefront of innovation in terahertz electronics, working on projects that push the boundaries of what is possible, aiming for the next generation of wireless systems, remote sensing and space terahertz instrumentation. You will be part of an inspiring and collaborative research environment and benefit from fruitful discussions with our industrial collaborators.

Major responsibilities
Your primary responsibility as a PhD student is to pursue your doctoral studies. You are expected to develop your scientific concepts and communicate the results of your research verbally and in writing. The position includes teaching at Chalmers' undergraduate level, which equates to 20 per cent of working hours.

Your research will be directed toward advancing terahertz semiconductor device electronics for sensor applications. It will be pursued at the Terahertz and Millimetre Wave Laboratory. You will fabricate demonstrators in our state-of-the-art and perform experiments in the terahertz characterisation facility ().
