Post-doctoral position in nano-optics - Hiring in process/Finished, not possible to apply

The research at the division of Solid State Physics is focused around different aspects of semiconductor physics, ranging from materials science to quantum physics, to different applications. The division also leads NanoLund, the major interdisciplinary research environment within nanoscience and nanotechnology at Lund University. Lund Nano Lab is a central key facility for fabrication of material and devices on the nanoscale. The division is also heavily involved in the undergraduate education, especially within the “Engineering Nanoscience” program.

The last decade, our research within the area of one-dimensional semiconductor structures, so called nanowires, has been at the international forefront. So far, our three main areas have been: epitaxial growth of nanowires, fundamental properties studied with transport physics and optical physics, and more applied nanoelectronics.

Subject description The position involves optical studies of nanostructures in semiconductors

Work duties The main duties involved in a post-doctoral position is to conduct research. Teaching may also be included, but up to no more than 20% of working hours. The position shall include the opportunity for three weeks of training in higher education teaching and learning. The postdoctoral fellow is expected to interact with the master students and the PhD students in the research group and contribute to meetings and seminars.

This position will involve studies of III-V nanowires with control over the crystal phases. In particular, the interfaces between wurtzite and zinc-blende GaAs and InP will be studied with the purpose of understanding the exciton gas which is bound to this interface. Studies of quantum wells defined by crystal phases, so-called polytype quantum wells, will also be performed. Also in this case, exciton gases will be studied. The long-term goal is to find new electronic phases at the exciton gas. The excitation gas can also be charged both positively and negatively. The experimental work will involve studies of individual nanowires, requiring good experience of optical micro-spectroscopy at low temperatures.

The optical techniques that will primarily be used are photoluminescence, excitation spectroscopy, selective excitation, Raman scattering and resonant Raman scattering. These techniques will be combined with electron microscopy such as scanning and transmission electron microscopy (SEM and TEM) such that the optically measured wires can be studied structurally. Certain theoretical calculations will be made with regards to electron structure. A close collaboration with theoretical physicists and crystal growers is expected.

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, completed no more than three years before the last date for applications. Under special circumstances, the doctoral degree can have been completed earlier.

Additional requirements:

• The subject of the doctorate degree should be physics or equivalent with focus on optical studies of low-dimensional semiconductors.
• Very good oral and written proficiency in English.

Assessment criteria and other qualifications 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.

Additional assessment criteria:

• Experience of photoluminescence, excitation spectroscopy and (resonant) Raman scattering of single nanowires.
• Experience in the construction of optical setups, including the controlling software.

The research is to a large extent interdisciplinary, and a broad competence profile and experiences from relevant areas of physics, materials science and nanoscience are of special value. Consideration will also be given to good collaborative skills, drive and independence, 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.

Terms of employment This is a full-time, fixed-term employment of a maximum of 2 years. The period of employment is determined in accordance with the agreement “Avtal om tidsbegränsad anställning som postdoktor” (“Agreement on fixed-term employment as a post-doctoral fellow”) between Lund University, SACO-S, OFR/S and SEKO, dated 4 September 2008.

Instructions on how to apply Applications shall be written in English. Please draw up the application in accordance with LTH’s Academic qualifications portfolio – see link below. Upload the application as PDF-files in the recruitment system. Read more:
