See below for further details.

2 PhD Studentships in Dynamic Tuning of Plasmonic Structures and Metamaterials
Stipend: €16,000 per annum for 4 years in addition to tuition fees.
Funding is available for Irish and EU students.
International applicants with full funding are welcome to apply. Proof of funding will be required at application stage.
Applications are invited for two four-year PhD studentships in the Nanophotonics and Plasmonics research team of Prof. Louise Bradley in the School of Physics, Trinity College Dublin. Successful applicants will join a vibrant team of students and postdoctoral researchers.  Trinity College Dublin, the University of Dublin is ranked 1st in Ireland and in the top 100 world universities by the QS World University Rankings. Further information on the Bradley group can be found at https://www.tcd.ie/Physics/research/groups/bradley-photonics/.


Project Description
Post-fabrication tuning of plasmonic structures and metamaterials across the visible and near-infrared spectral ranges continues to pose significant challenges. This research will consider different options for controlling the plasmonic properties of noble metal antenna coupled to quantum emitters, for example phase change materials or 2D materials. One of the PhD positions will concentrate on phase change materials with the other on 2D materials. Both material options are promising routes to dynamic electrical controlled of plasmonic coupled systems, but significant research is required to determine the optimal implementation.
Each project will involve experiments and simulation. The successful applicants will develop skills in materials growth via sputtering and/or plasma laser deposition, He-ion and e-beam lithography and imaging as well as optical and electrical characterisation of plasmonic devices coupled to emitters such as quantum dots. Complementary simulations to design structures and interpret experimental observations will be performed using finite difference time domain software, which is available within the group.
These studies will provide an excellent base for a career both in academia and in high-value industry. The research is funded by Science Foundation Ireland.
The successful candidates will be highly self-motivated and have a first class or upper-second class honours degree from an Irish university, or an equivalent from another country, in Physics, Theoretical Physics, Material Science or Nanoscience, with a strong interest in photonic materials and applications. Knowledge of Chemistry would also be helpful but not essential. A M.Sc. in a related area would be an advantage. A high level of written and oral communication skills in English is essential.


How to Apply
Prospective candidates should send a detailed CV, a covering letter outlining their educational background, research interests and motivations, transcript of your marks if available, and the names and contact details of three academic referees to Prof. Louise Bradley (bradlel@tcd.ie). Following receipt of your application, Prof. Bradley will be available to discuss the research programme in further detail. The anticipated start date of the project is December 2017 but this can be flexible to the timetable of the successful candidate. 
All applicants whose first language is not English and who have not been educated through the medium of English must present one of the following qualifications in the English language to be eligible for registration in the University:

  • IELTS: Grade 6.5 overall
  • TOEFL: 88 internet-based, 570 paper-based, 230 computer-based
  • University of Cambridge: 
    Proficiency Certificate, Grade C or better (CEFR Level C1 or C2) 
    Advanced Certificate, Grade C or better (CEFR Level C1 or C2) 
  • Pearson Test of English (Academic) - PTE Academic: a minimum score of 63 to be eligible (with no section score below 59)

Please note that test scores are only valid for 2 years.

 

Other PhD Opportunities

The group has a range of projects areas and is always interested in recruiting motivated students. If you have other full funding or are EU students interested in submitting an Irish Research Council scholarship application contact Prof. Bradley. The IRC deadline for the current year is November 1st, 2017.

Please send a CV and a brief cover letter, including name and contact details of at least two referees who can provide academic references on your behalf.

Post-doctoral Researcher position in Electrical Control of Plasmon-Emitter Coupled Systems

Salary range: €36489 to €43,349 per annum.
Salary is point is determined by experience and number of years post-PhD.

Applications are invited for a Post-Doctoral Researcher position in the Nanophotonics and Plasmonics research team of Prof. Louise Bradley in the School of Physics, Trinity College Dublin. The appointment will be for two years with the possibility for a further two years subject to performance and funding. The successful applicant will join a vibrant team of students and postdoctoral researchers.  Trinity College Dublin, the University of Dublin is ranked 1st in Ireland and in the top 100 world universities by the QS World University Rankings. Further information on the Bradley group can be found at https://www.tcd.ie/Physics/research/groups/bradley-photonics/.

Project Description
The project will explore dynamic electrical control of plasmon-emitter coupled systems. Routes to electrical tuning of the near-field properties of plasmonic structures will be investigated. In particular, the project will consider plasmonic systems modulated by the properties of phase change materials and novel 2D materials. Experience in the theoretical modelling and numerical simulation techniques, such as finite different time domain or finite element modelling is essential. These techniques will be used to identify optical structures for electrically tuneable properties of plasmonic and metamaterials as well as their impact on the emission quantum emitters. Examples of relevant publications from the group are given below.The successful applicant must be able to work well within a team and to work closely with experimentalists for practical realisation of theoretical results and interpretation of experimental data. There is also the possibility for the successful applicant to be involved in complementary experimental research, and relevant experimental experience in materials growth and optical characterization of nanophotonic structures would be an advantage. .
These studies will provide an excellent base for a career both in academia and in the high-value industry. The research is funded by Science Foundation Ireland.
The successful candidates will be highly self-motivated and able to work independently. They have a first class or upper-second class honours degree from an Irish university, or an equivalent from another country, in Physics, Theoretical Physics, Material Science or Nanoscience. They must have a Ph.D. in a topic relevant to the needs of this project, with experience of developing theory and/or numerical simulations of plasmon coupled systems. Relevant experimental experience in Physics or Knowledge of Chemistry would also be helpful but not essential. A high level of written and oral communication skills in English is essential. The candidate must be interested in assisting Ph.D. and short-term project students working on related topics in the group.
