PhD Studentship in Ocean Biogeochemistry, MPI-M, Germany

/ February 28, 2011 Leave a Comment

The applicant will be part of the Research Group Ocean Biogeochemistry in the Department The Ocean in the Earth System. The research will focus on reconstructing the ocean carbon cycle and its interactions with climate during the Paleocene-Eocene Thermal Maximum. The main tool will be the existing Earth system model of the MPI-M, which includes the ocean biogeochemistry model HAMOCC. One of the objectives of the project will be to improve our understanding of the PETM and its potential to serve as an analogue of the future climate perturbations due to anthropogenic CO2 emissions.

Requirements: We are looking for a highly motivated individual with a M.Sc. or diploma in Geosciences, Oceanography, Environmental Sciences, Physics or a related field. Experience, or a strong interest in biogeochemistry and modeling is of advantage. Good programming skills (FORTRAN on Unix platforms) are desirable, since the applicant will use facilities of the high performance computing centre. The working language is English. The MPI-M encourages doctoral students to participate in the International Max Planck Research School on Earth System Modeling.

Scholarship Application Deadline: before 15th of March 2011

2011- 2012 PhD Studentships in Law at Kent Law School, UK

/ February 28, 2011 Leave a Comment

Kent Law School (KLS) invites applications for full time research studentships leading to the degree of PhD commencing in September 2011. Candidates will initially register for a full time MPhil research degree at the University of Kent at Canterbury. One of these studentships will be awarded specifically for research in the area of International Law and, although the recipient will be part of the Canterbury campus postgraduate community, the associated teaching responsibilities will take place at the University’s Medway campus. The funding will be available for one year in the first instance, extended (for registered students only) for a second year providing verifiable progress has been made (in teaching and research), and extended for a third year providing the candidate has upgraded from MPhil to PhD.
The successful applicants for the studentships will receive a maintenance grant equivalent to that offered by ESRC (£13,590 in 2010/11) and tuition fees paid at the home/EU rate (£3,950 in 2010/2011).Those awarded a studentship will normally be expected to teach a maximum of four hours per week in term time on an undergraduate English law module, at the direction of the Head of Department.  Some bursaries (for example, reducing overseas fee to home fee rate) may also be available.

Scholarship Application Deadline: 15 April 2011

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

/ February 28, 2011 Leave a Comment

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.

Scholarship Application Deadline: 31 March 2011
