PhD student in Physics at the Department of Physics and Astronomy

Published: 2024-03-12

The research conducted at the Department of Physics and Astronomy encompasses a wide range of physics topics, distributed over nine divisions. The department is located in the Ångström laboratory and employs nearly 400 people, 100 of whom are doctoral students. It offers a broad physics curriculum to undergraduate and graduate students, participation in nationally and internationally leading projects for researchers, and opportunities for partnership with industry and various outreach activities.

The Ion Physics group within the Department of Physics and Astronomy investigates advanced materials for applications in fusion energy, smart windows, hydrogen storage & nanoelectronics in particular using beams of swift ions to link structure and composition on a true atomistic scale with physical properties and macroscopic functionality. The group also performs fundamental investigations of the interaction of ions in matter to obtain a better understanding of the underlying physics and improved methods. These methods permit to determine concentrations and depth profiles of atoms and molecules in a material with very high accuracy for samples from biological, environmental and technological contexts. They can also be used to tailor material properties such as crystallinity or local chemical composition. A 5 MV tandem accelerator, a 350 kV high current ion implanter and a Low-Energy Ion Scattering System form the experimental platform.

Uppsala University hereby declares a PhD student position, at the Department of Physics and Astronomy, to be open for application. The PhD-studies will focus on investigating dynamic phenomena induced in the electronic systems of materials by ultrashort ion pulses impinging on the material. An improved understanding of the underlying complex many-body physics provides unique benchmarking information for advanced time-dependent computational approaches and is of ultimate relevance for tailored materials modification and analysis using ion beams used from cancer therapy to synthesis of electronic compounds. The work will be of primarily experimental character.

Duties
The project is focused on experimental studies of the interaction of energetic ions with materials. Specifically, this will include:

• Experiments to measure energy loss and charge state distributions of ions as well as secondary particles emitted upon ion impact in the interaction with complex self-supporting crystalline target systems.
• Operation and development of Time-of-flight spectrometers and corresponding ion accelerators.
• Preparation of ultrathin, high quality target systems ranging from self-supporting single crystalline thin films to 2D-materials.
• Handling and analysis of complex datasets, evaluation and simulation using Monte-Carlo and Molecular dynamics approaches.

The PhD position is for four years, extendable to a maximum of five years including departmental duties at a level of at most 20% (typically teaching). Information about doctoral education, eligibility requirements and admission rules can be found on the web site of the Faculty of Technology http://www.teknat.uu.se/utbildning/forskarniva/ .

Requirements
To meet the entry requirements for doctoral studies, you must

• hold a Master’s (second-cycle) degree in natural science discipline;
• be able to demonstrate excellent communication skills in English as well as excellent academic records;
• personal capabilities necessary to carry out fully the duties of the appointment.

Appointment as a graduate student requires that the holder is admitted or will be admitted to PhD studies, where the applicant’s ability to successfully complete the doctoral studies will be decisive.

Additional qualifications
It is considered advantageous a background in either a Physics, Material Science or equivalent; strong data analysis skills; past experiences in vacuum systems. Experience in materials research with ion beams is beneficial.

Rules governing PhD students are set out in the Higher Education Ordinance chapter 5, §§ 1-7 and in Uppsala University's rules and guidelines .

About the employment
The employment is a temporary position according to the Higher Education Ordinance chapter 5 § 7. Scope of employment 100 %. Starting date 6 May 2024 or as agreed. Placement: Uppsala

About the application: Applications should include a brief description of research interest and past experience, a CV, copies of exams, degrees and grades, a copy of your Master thesis (or a draft thereof) and other relevant documents.
