PhD position: STM and AFM Studies of Cross Sections Containing Embedded Nanostructures, Aalborg University, Denmark

Position No.

At the Faculty of Engineering and Science, Department of Physics and Nanotechnology a number of PhD stipends are available within the general study programme in Mathematics and Physics. The stipends are open for appointment from 1st of December 2010.

Job description
The projects will be closely related to ongoing research project in the fields of light emitting semiconductor nanostructures, enhancement of light absorption in solar cells by plasmons, and fabrication and testing of active plasmonic structures.
The PhD projects should be described within the following fields:

1. Growth and optical characterization of nanocrystalline Si layer for photovoltaics. Nanocrystalline Si is a very promising material as active layer in solar cells. In the project such layers should be synthesized and characterized. In particular the optical properties should be investigated as a function of various parameters such as size and surface terminations of the nanocrystals.
2. STM and AFM studies of cross sections containing embedded nanostructures. The functionality of embedded nanostructures intended for instance for light scattering and field enhancement in solar cells depends strongly on size, shape, position, and in some cases also structure of the nanostructures. In the project the possibilities for using scanning probe techniques for characterization of nanostructures embedded in both insulating and semiconducting layers should be investigated.
3. Coupling of light emission from nanostructures to plasmonic waveguides. An important element in the development of active plasmonic components, for instance for sensor technology, is integration of light emitting elements that couple directly to plasmons and to guiding structures. In the project light emitting semiconductor nanostructures should be synthesized on or deposited on plasmonic structures and the coupling of light to plasmons should be characterized.

Research at Department of Physics and Nanotechnology covers various aspects of nanotechnology in relation to optics, materials, biotechnology, and molecular engineering. Existing strengths in the fields of optics and materials cover theoretical studies of electronic and optical properties of nanostructures, linear and nonlinear optical properties of nanostructures (thin films, wires and dots, plasmonic structures), electronic and magnetic properties of nanostructures, photovoltaic cells, diffractive optical components, and different aspects of surface physics.

You may obtain further information from Professor Kjeld Pedersen , Department of Physics and Nanotechnology , phone: +45 9440 9220 , email: kp@nano.aau.dk concerning the technical aspects of the stipend.

PhD stipends are allocated to individuals who hold a Masters degree. PhD stipends are normally for a period of 3 years. It is a prerequisite for allocation of the stipend that the candidate will be enrolled as a PhD student at the Doctoral School of the Faculty of Engineering and Science, in accordance with the regulations of Ministerial Order No. 18 of January 14, 2008 on the PhD Programme at the Universities. According to the Ministerial Order, the progress of the PhD student shall be assessed every six months. It is a prerequisite for continuation of salary payment that the previous progress is approved at the time of the evaluation.

The qualifications of the applicant will be assessed by an assessment committee. On the basis of the recommendation of the assessment committee, the Dean of the Faculty of Engineering and Science will make a decision for allocating the stipend.

For further information about stipends and salary contact Ms. Maj-Britt Trolle Ståhl, The Faculty of Engineering and Science, email: mts@adm.aau.dk, phone: +45 9940 7582.

The faculty have a research school, The Doctoral School of Engineering, Science and Medicine: www.phd.ins.aau.dk and a Network for all PhD students: www.pau.aau.dk

Appointment and salary as a PhD fellow are according to the Ministry of Finance Circular of October 1, 2008 on the Collective Agreement for Academics in Denmark, Appendix 5, regarding PhD fellows, and with the Ministry of Finance Circular of June 13, 2007 on the employment structure at Danish Universities.
