Postdoctoral fellow in Physics: novel ultra-wide bandgap semiconductor technology

Description of the workplace
The position is placed at 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 large bandgap semiconductors has been at the international forefront.

Subject description
The subject of this project is to develop novel ultra-wide bandgap semiconductor technology based on AlN and related alloys. This includes growth by metalorganic vapor phase epitaxy and developing AI approaches for deterministic synthesis to achieve n- and p-type conductive AlN and related UWBG Al containing alloys. Doping and processing of ultra wide bandgap semiconductors present challenges, but it can enable electronic devices with substantially better performance as compared to traditional power electronic devices based on Si and SiC. The position is part of a large initiative funded by KAW to develop a comprehensive platform that will enable, for the first time, deterministic control of atomic configurations in UWBG materials. The project combines leading expertise and unique know-how in theory, modelling, synthesis, atomic-scale imaging and spectroscopy, and nanoelectronics aiming to unlock the potential of AlN and UWBG materials for next-generation energy technologies.

The research work will be conducted in close collaboration with PhD-students and researchers working with power electronic devices within the competence center for III-Nitride technology C3NiT and within a European network within the WBG Pilot Line, but also with experienced researchers within materials growth and materials characterization, at the departments of solid state physics and synchrotron radiation physics.

Work duties
The main task of a postdoctoral fellow is to conduct research. You will work closely with other postdoctoral fellows and with doctoral students, and there is thus the possibility of earning merit as a supervisor. Teaching may also be part of the duties, but not more than one fifth of the working hours. Within the framework of the position, there is an opportunity for three weeks of training in higher education pedagogy. The purpose of the position is to develop independence as a researcher and create conditions for further merit.

The research tasks will include:

• Epitaxial growth of AlN, AlGaN and related device heterostructures by MOCVD  (Lund Nano Lab).
• Development of data-driven and AI approaches for deterministic synthesis of AlN during MOCVD to establish atomistic understanding and control of growth.
• Develop innovative strategies to control of doping and native defects in AlN and high-Al content AlGaN.
• Advanced structural and spectroscopic characterization of defects in AlN and high-Al content AlGaN.

Qualification requirements
Appointment to a post-doctoral position requires that the applicant has a PhD, or an international degree deemed equivalent to a PhD, within the subject of the position. The certificate proving the qualification requirement is met, must be received before the employment decision is made. Priority will be given to candidates who have graduated no more than three years ago before the last day for application. Under special circumstances, the doctoral degree can have been completed earlier.

Additional requirements:

• Very good oral and written proficiency in English.
• Substantial hands-on experience of epitaxial growth of AlN or related materials by MOCVD.

 
Assessment criteria
This is a career development position primarily focused on research. The position is intended as an initial step in a career, and the assessment of the applicants will primarily be based on their research qualifications and potential as researchers. Particular emphasis will be placed on research skills within the subject.

For appointments to a post-doctoral position, the following shall form the assessment criteria:

• A good ability to develop and conduct high quality research.
• Teaching skills.

Other qualifications:

• Experience of epitaxial growth of AlN, AlGaN and related device heterostructures by MOCVD.
• Advanced structural and spectroscopic characterization of defects in AlN and high-Al content AlGaN.
• Deep knowledge of semiconductor physics.
• Keen interest and/or experience in application of AI approaches.
• Knowledge of ultrawide bandgap semiconductors.
• Proven experience in writing scientific papers.

Consideration will also be given to how the applicant’s experience and skills complement and strengthen ongoing research within the department, and how they stand to contribute to its future development.

We offer
You will be included in a team of researchers at NanoLund, a highly visible nanoscience center that offers excellent career development, an open and inclusive research environment with an active community of PhD students and postdocs, and access to a wide range of state-of-the-art capabilities within characterization, nanofabrication and modelling.

Lund University is a public authority which means that employees get particular benefits, generous annual leave and an advantageous occupational pension scheme.
