Pre-selection is in progress for foreign students applying for a position in a PhD Program for the Academic Year 2011/12.The number of positions funded by the University will be established by the Graduate School after 10 June 2011. Foreign students wishing to apply for admission to a PhD Program for the Academic Year 2011/12 must submit an application no later than 25 April 2011.Some doctoral courses have specific conditions of admission. Those will be advertised on the following web page: (These conditions may include the primary language of the program and its educational activities — e.g., English or Italian).

Foreign students will be evaluated by submitting an online application by 25 April 2011. At the conclusion of the online application process, applicants must attach in electronic format a “pdf” file with a maximum size of 15 MB containing:
1. A Curriculum Vitae with details of achieved degree(s), relevant examination results and/or results of degree requirements with assessment and/or grade (i.e., transcript details), and the date of degree achievement.
2. A research proposal (maximum size of one (1) page on A4 paper)
3. A List of Publications
Foreign students are required to provide two recommendation forms & corresponding letters from two university professors either in Italy or abroad.
Eligible candidates whose application has passed preliminary screening will be invited to take part in a Skype interview with the Coordinator (or their delegate) of the applicant’s desired program of study.
The Doctoral School will publish the list of candidates granted a Skype interview and the timetable of those interviews.

Doctoral Scholarship in GaN-based Single Photon Emitters, Germany: Quantum Metrology

The interest in single-photon-emitters rises continuously since quantum communication based on the polarization of single photons has already been demonstrated. Unfortunately up to now almost all single-photon sources are pumped optically which makes the realization of a widespread communication network very complex.

For this reason it would be of great advantage to fabricate electrically pumped single-photon-sources. This can be realized e. g. by fabricating LED structures with active regions, where only single ions are incorporated, leading to single photon emission. The LEDs could be driven electrically and the optical energy of the LED is transferred to the single transition available in the active region of the LED. Today, only very few reports on electrical single photon sources are available.

Zinc is a very promising candidate as a single photon emitter in GaN based LEDs. Zn acceptors show efficient emission in the blue spectral range. Zn creates a deep acceptor level 0.3 eV – 0.4 eV above the valence band. Furthermore, Silicon-codoping is required for efficient optical emission, resulting in a very bright photo-luminescence at 2.9 eV (~ 430 nm) which has been assigned to donor-acceptor (DA) transitions.

The goal of this thesis is to investigate single transitions in GaN based LEDs with Zn and Si co-doping. LEDs will be fabricated by MOCVD and processed in house. A thorough analysis of the relevant optical transitions by time resolved optical characterization will allow to get information on the nature and characteristics of the transitions, as well as on the emission statistics in order to get a quantitative handle on the statistical quality of single photon emission correlated with that.

Roskilde International Doctoral Summer School, Denmark: Education, Migration, Literature, Technologies

The aims of the Roskilde Summer School are threefold:
– to help students grasp and critically engage with the notions of identity and intercul-turality and see how they are related
– to get to know various research methods that can help students to work within cul-tural and social complexity
– to discuss their own research topics and to get to test various research tools that can help them to move on in/improve their research
The Summer School is meant to be transdisciplinary, and the target group is PhD students from all disciplinary backgrounds who are especially interested in methodologies related to this field of study.

Scholarship Application Deadline: 28 February 2011
