The Maser lab at Saarland University (UdS) has an opening for a PhD candidate, salary in accordance with the German TV-L salary scale, pay grade: E13 TV- L, duration of employment: 3 years, volume of employment: 75 % of standard working time. During this PhD project a miniaturised chip-scale diamond maser device is developed. The candidate will represent a synergetic link between natural and applied science, translating a laboratory scale experiment towards a fully integrated microchip technology.

The UdS Maser lab has expertise in studying and characterising room-temperature solid-state masers, within the framework of cavity quantum electrodynamics. A miniaturisation into a hand-held device relies on this deep understanding of the physical principles, presenting an optimal starting point for this project. A novel integrated maser device has great potential applications in sensing, communication, timekeeping and quantum technologies.

Translating the bulky maser laboratory experiment onto a chip-scale platform will be conducted in close collaboration with the Institute of Smart Sensors at the University of Stuttgart. There, a chip-scale microwave resonator circuit will be developed and optimised for the use with two maser gain media, pentacene doped p-terphenyl and NV-centres in diamond. The characterisation methodology will be developed, feeding into the creation of a prototype device.

• Characterisation of novel chip-scale maser devices, based on integrated circuits
• Perform experiments using steady-state microwave spectroscopy, as well as time-resolved spectroscopy methods
• Design and development of new experimental setups for characterisation
• Perform data analysis and simulations to complement experimental work
• Help produce independent and original research within the UdS Maser lab, submit publications to peer-reviewed journals
• Contribute to the induction of other research staff and students
