Doctoral student in Physics: Atomic scale dynamics of nanostructures for photonics and electronics

Updated: 2 months ago
Job Type: FullTime
Deadline: 05 May 2021

The Division of Synchrotron Radiation Physics (www.sljus.lu.se ) is a part of the Department of Physics and has about 50 employees. The focus of the research is on experimental studies of electronic, structural, and chemical properties of materials, as well as on accelerators and instrumentation for Synchrotron radiation. The division has many connections to the MAX IV laboratory (www.maxiv.lu.se/ ) situated in Lund, which holds a 4th generation synchrotron as well as to Lund Laser Center (www.llc.lu.se ) providing advanced laser sources. In addition, the division host one of Sweden's largest facilities for scanning tunneling microscopy (STM) and atomic force microscopy (AFM).

NanoLund (www.nano.lu.se ) is the Centre for Nanoscience at Lund University. NanoLund is today Sweden’s largest research environment for nanoscience, engaging approximately 270 PhD students and scientists in the Faculties of Engineering, Science, and Medicine. It also operates Lund Nano Lab, a state-of-the-art cleanroom for the synthesis, processing, and characterization of semiconductor nanostructures.

Work duties

The project center on studies and control of dynamics down to the atomic length (nano/picometer) and time (femto/attosecond) scales through excitation by advanced light sources such as ultrafast lasers and/or electrical operation of nanoscale devices. A broad range of nanostructures and devices will be explored, with a focus on 0D, 1D and 2D metal-semiconductor hybrid systems with potential novel applications in renewable energy and computation.

III-V semiconductor nanowires constitute a central sample platform which is unique due to its wide range of highly reproducible atomically precise complex lateral and vertical heterostructures. It can be combined with single crystalline metal nanostructures, functional Oxides, 2D materials, and Silicon. The successful candidate will work with fabricating devices and samples based on these nanostructures as synthesized by local and international partners. The work include nanolithography, nanoprobe manipulation, ion beam milling and various types of evaporation of materials. Nanoscale imaging will be done by PhotoEmission Electron Microscopy (PEEM) using a mobile setup that can be placed at several specialized laser sources that allow studies of femtosecond and attosecond phenomena. This will be correlated to a detailed understanding of chemistry and electronic structure to the few nm level on the very same objects, using for examples Scanning Probe Microscopy and synchrotron based methods.

The work will be done in collaboration with senior scientists as well as graduate students providing expertise, equipment and nanomaterials within photonics/electronics, advanced lasers, synthesis as well as characterization.

This work will be embedded in the NanoLund (www.nano.lu.se ) Centre for Nanoscience and it will involve researchers and facilities from the Lund Laser Centre (www.llc.lu.se ).

The main duties of doctoral students are to devote themselves to their research studies which includes participating in research projects and third cycle courses. The work duties can also include teaching and other departmental duties (no more than 20%). Participation in several PhD schools (e.g. on nanoscience, experimental methods and analysis and advanced microscopy) is offered.

Admission requirements

A person meets the general admission requirements for third-cycle courses and study programmes if he or she:

  • has been awarded a second-cycle qualification, or
  • has satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the second cycle, or
  • has acquired substantially equivalent knowledge in some other way in Sweden or abroad.

A person meets the specific admission requirements for third-cycle studies in Physics if he or she has:

  • passed an independent project (e.g.degree project) of at least 30 credits in a relevant subject

Equivalent knowledge acquired through corresponding programmes will be assessed individually. In order to enable interdisciplinary initiatives and important specialisations in certain areas, students with qualifications in subjects other than Physics may be considered for admission.

Finally, the student must be judged to have the potential to complete the programme.

Additional requirements:

  • Very good oral and written proficiency in English.

Other assessment criteria are experience and ability in

  • Working with nanofabrication of nanophotonic/electronic devices.
  • Understanding on electron dynamics in nanoscale systems.
  • Working with advanced laser systems
  • Laboratory work, including advanced surface microscopy and ultrahigh vacuum technology.
  • In the scientific interaction with researchers from other disciplines and from other countries.

Basis of assessment

Selection to postgraduate studies is based on the expected ability to perform well in the studies. The evaluation of the ability to perform well is based primarily on the results of studies at the basic and advanced levels, in particular:

  • Knowledge and skills relevant to the thesis project and the subject of the study.
  • An assessment of ability to work independently and to formulate and tackle research problems.
  • Written and oral communication skills
  • Other experience relevant to postgraduate studies, such as professional experience.
  • Consideration will also be given to good collaborative skills, drive and independence, and how the applicant, through his or her experience and skills, is deemed to have the abilities necessary for successfully completing the third cycle programme.

    Terms of employment

    Only those admitted to third cycle studies may be appointed to a doctoral studentship. Third cycle studies at LTH consist of full-time studies for 4 years. A doctoral studentship is a fixed-term employment of a maximum of 5 years (including 20% departmental duties). Doctoral studentships are regulated in the Higher Education Ordinance (1993:100), chapter 5, 1-7 §§.

    Instructions on how to apply

    Applications may be written in English and include a cover letter stating the reasons why you are interested in the position and in what way the research project corresponds to your interests and educational background. The application must also contain a CV, degree certificate or equivalent, and other documents you wish to be considered (grade transcripts, contact information for your references, letters of recommendation, etc.).

    The English version of this announcement is an interpretation of national formalities expressed in the Swedish text. In case of uncertainties, the Swedish text applies.
