Lund University was founded in 1666 and is repeatedly ranked among the world’s top universities. The University has around 46 000 students and 8 500 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.
The PhD position is placed at the Division of Solid State Physics at the Department of Physics, a division with around 100 employees where extensive research is carried out centered on various aspects of nanophysics, ranging from materials science to bio- and quantum physics to various applications. The division is a central part of NanoLund, Lund University's large interdisciplinary research Centre on nanoscience and nanotechnology.
The division hosts the research group of Prof Vanya Darakchieva whose research over the past twenty years on the fabrication and advanced characterization of wide- and ultra-wide bandgap semiconductors has been at the international forefront.

As a doctoral student, you are both admitted as a student and employed at Lund University.
As a doctoral student, you will be trained in a scientific approach. In short, you will be trained to think critically and analytically, to solve problems independently using the right methods, and to develop an awareness of research ethics. In addition, you will have the opportunity to work on projects, to develop your leadership and pedagogical skills. Throughout your studies, you will be guided by supervisors. Doctoral studies end with a thesis and a doctoral degree.

The project aims to establish a deterministic approach for creating quantum defects in AlN for room temperature applications. The focus is on the development of a closed-loop research framework that combines advanced MOVPE growth using carbon-free (halide-based) precursors, machine-learning-driven optimization based on Bayesian methods, and a novel THz spectroscopic that directly probes defect properties. The project builds on Lund University's strong expertise in MOVPE of III-nitrides and III-oxides, enabling high-purity materials and improved device performance. The work will be conducted in close collaboration with Chalmers University to develop ML approaches that accelerate materials synthesis by efficiently navigating high-dimensional, strongly coupled process spaces. The position is part of a larger initiative within the Wallenberg scholar program on next-generation UWBG semiconductors for quantum technologies and green electronics.
You will primarily devote yourself to your doctoral programme, which includes participation in research projects as well as third cycle courses, seminars and conferences.
The work duties include MOVPE growth of AlN and Sc-alloyed AlN for systematic mapping of the growth parameter space, including temperature, pressure, precursor flow rates, and the V/III ratio. In addition, structural characterization by X-ray diffraction, Atomic Force Microscopy, and electrical characterization by C-V. The work will also include developing a multi-objective Bayesian optimization framework to simultaneously reduce native defect formation and unintentional impurity incorporation.
The duties also include participation in teaching and other departmental work (however, a maximum of 20% of working hours).
To be eligible for admission and employment as a doctoral student, you must fulfil the requirements below.
