A Doctoral Student Position in Probing the Electronic Structure of Semiconductor Heterojunctions via Time-resolved Spectroscopies

 

We, at the University of Oulu, work as part of the international science community to produce new scientific information and science-based solutions. We are committed to educate future pioneers to build a more sustainable, intelligent and humane world. Creating new, taking responsibility and succeeding together are values that build a strong foundation for all our actions. Our university's several specialized research and service units enable extensive and diverse development and career opportunities for experts in various fields. The university is an international scientific community, with 15,000 students and 3,000 employees. More information http://www.oulu.fi/english/    Heterogenous and heterojunction semiconductors are believed to have superior properties over their individual components due to their specific electronic structure. Experimental investigations of the unique but fundamental features are important in exploring the mechanisms leading to the enhanced performance.  We are now looking for a Doctoral student in spectroscopic investigation of electronic structures of semiconductor heterojunctions by time-resolved spectroscopies. You will focus on spectroscopic investigation of electronic structures and excitonic behaviors of semiconductor heterojunctions. The experimental work is expected to be performed by means of in house and synchrotron-based photoluminescence spectroscopy, both in steady state and time-resolved mode. The work will be carried out as a part of an international and multidisciplinary research team dedicated both to experiment and theory. The tasks of the candidate also include publishing results in leading international scientific journals, obtaining course credits in according to the PhD training plan, and completing the doctoral degree by the due time.   Description of the research environment The work is carried out in the Functional Materials Group (FunMaters, https://www.oulu.fi/en/research-groups/functional-materials) of Nano and Molecular Systems Research Unit (NANOMO, http://www.nanomo.fi) at University of Oulu. The group consists of one associate professor, seven postdoctoral researchers and three PhD students. The group is chairing one ERC-Consolidator Grant, one Business Finland Research-to-Business funding, one EIT Raw Materials funding and hosting one Spanish Margarita Salas Fellowship. The research of the group covers a wide domain in materials physics, with special emphasis on photocatalysis, bio-inspired surface treatment, and advanced metals. The NANOMO research unit focuses on molecular scale materials physics and novel applications of spectroscopic and imaging techniques. The research topics include electronic structure research in nanomaterials, functional materials (e.g. steel, carbon negative materials, and nanocatalysts), biomedical research, mesoscopic quantum structures in materials, and physics didactics. The main external funding sources are the European Union ERC, Horizon2020 programs, EU EIT-RawMaterials and ERDF funds, Academy of Finland and other national and international funds. The unit coordinates Finnish national participation in the MAX IV Laboratory synchrotron radiation facility, participates in the operation of the FinEstBeAMS beamline, and contributes to the European Free Electron Laser Eu-XFEL project.   Requirements for the post Master’s degree in physics, chemistry, or another relevant field The degree must be completed with good grades, latest by the start of the employment Good proficiency in the English language (both written and spoken) Good communication skills and the ability to work as a part of team and independently   Assessment criteria and other qualifications The candidates will be evaluated based on their qualifications, suitability for the research topic, and potential as researchers. The following merits are seen as a strong advantage: Experience in time-resolved luminescence spectroscopy technique under photo-, laser and X-ray excitations. Good knowledge of synchrotron radiation and experience in synchrotron-based experiments. Experience in chemical synthesis of inorganic materials. Good knowledge in materials characterization methods including XRF, microscopy, mass spectroscopy, XRD, etc.   What we offer You will be a part of a highly talented research group. You will receive support from your team and supervisor, so that you can excel in your studies and research In addition to modern research facilities, we offer you personnel benefits such as occupational healthcare and sport and culture benefits The position is expected to start from 01.05.2022. However, due to possible travel restrictions and administration issues, a delay of couple of months may also be within considerations.   The position is fixed-term for 4 years, the trial period of 6 months is applied to the position. The salary for doctoral student will be in accordance with the Finnish universities salary system for teaching and research personnel): demand level 2 – 4. In addition, a personal salary component based on work performance will be paid (maximum of 50% of the job-specific component). Typical salary for a Doctoral Student is 2400- 2700 € per month (before taxes).   How to apply Applications, together with all relevant appendices, should be submitted using the electronic application form by 15th March, 2022 at 23:59 (EET). The application should be written in English and include the following: 1) A motivation letter (max. 2 pages) summarizing the applicant’s professional experience and expertise and describing why the applicant is interested in this position.
