PhD Candidate in Physics: AI-Accelerated MOCVD Growth of AlN

Popis:

Lund University was founded in 1666 and is consistently ranked as one of the world's leading universities. Here, approximately 46,000 students and 8,500 employees work in Lund, Helsingborg, and Malmö. We are united in our mission to understand, explain, and improve our world and people's conditions. Description of the Activities The PhD position is affiliated with the Division of Solid State Physics at the Department of Physics, a division with approximately 100 employees conducting extensive research focused on various aspects of nanophysics, from materials science to bio- and quantum physics with various applications. The division is a central part of NanoLund, which is Lund University's major interdisciplinary research center for nanoscience and nanotechnology. The division is home to Prof. Vanya Darakchieva's research group. Research over the past twenty years on the fabrication and advanced characterization of semiconductors with wide and ultra-wide bandgap has been at the international forefront.

As a research student, you will be trained in a scientific approach. In short, you will gain practice in critical and analytical thinking, you will learn to solve problems independently using appropriate methods, and you will develop research ethics awareness. Additionally, as a PhD candidate, you will have the opportunity to work on projects, develop your leadership skills, and strengthen your pedagogical abilities. Throughout your studies, you will be guided by an advisor. Doctoral studies conclude with a dissertation and a doctoral degree. More about being a PhD candidate at LTH: lth.se Subject and Project Description The project aims to develop a deterministic method for creating quantum defects in AlN for room-temperature applications. The focus is on how a combination of advanced MOVPE growth with halide-based precursors (halogen-free), machine learning-driven optimization based on Bayesian methods, and a new THz spectroscopy that directly examines defect properties form a closed-loop research framework. The project builds on Lund University's strong expertise in MOVPE of III-nitrides and III-oxides, enabling materials with high purity and improved performance of electronic components. The work will be conducted in close collaboration with Chalmers University of Technology to develop machine learning methods that accelerate materials synthesis by efficiently navigating high-dimensional, strongly coupled process spaces. This position is part of a larger initiative within the Wallenberg Scholar program on next-generation ultra-wide bandgap semiconductors for quantum technology and green electronics. Duties You will primarily focus on your doctoral research, which includes participation in research projects, doctoral courses, seminars, and conferences. The duties include MOVPE growth of AlN and Sc-doped AlN for systematic mapping of growth parameters, including temperature, pressure, precursor flow rates, and the V/III ratio. Additionally, structural characterization using X-ray diffraction and atomic force microscopy and electrical characterization with IV measurements are included. The work will also include developing a framework for multi-objective Bayesian optimization to simultaneously reduce the formation of native defects and unintentional impurity incorporation. The duties also include participation in teaching and other departmental activities (however, no more than 20% of work time). Qualifications To be admitted and employed as a PhD candidate, you must meet the requirements below. Eligibility Requirements You meet the basic eligibility requirement for doctoral-level studies if you have: completed a degree at advanced level, or completed course requirements of at least 240 higher education credits, of which at least 60 credits at advanced level, or acquired equivalent knowledge by other means. You meet the specific eligibility requirement for physics if you have: at least 30 higher education credits at advanced level relevant to the subject area, including a thesis of at least 15 advanced-level credits, or a degree in technical physics or a related field, or a master's degree in physics or a related field. Other Requirements To benefit from the current doctoral education, the following are also required: strong ability to work independently and ability to formulate and approach scientific problems. strong written and verbal communication skills good collaboration skills very good knowledge of English, both spoken and written Meritorious Qualifications For this doctoral education, the following are considered meritorious: experience with epitaxial growth of semiconductors with extremely wide bandgap experience with structural and electrical characterization of epitaxial semiconductors with extremely wide bandgap experience with AI methods for materials synthesis in-depth knowledge of semiconductor physics knowledge of semiconductors with ultra-wide bandgap See the full announcement on Lund University's website / About the University / Work with Us.
