Reza Arkani

Marie Curie Early Stage Researcher

As a Marie Sklodowska-Curie early stage researcher in Photonics Theory Group of Tyndall National Institute, Reza undertook the project on “Design and Analysis of Hydrogenated Dilute Nitride Semiconductors”. This project aims to investigate the electronic structure of dilute nitride metamorphic nanostructures grown across the PROMIS consortium as an Initial Training Network funded by the EU Horizon 2020 Marie Skłodowska-Curie Actions. I undertake calculations to establish the impact of N on the electronic structure of dilute nitride GaSbN and InGaAsN layers grown on GaAs and of InAsSbN grown on AlInAs.

The results of these calculations will be used as input to higher level models to:

  • design and optimise the emission characteristics of In(N)AsSb/AlInAs metamorphic structures grown by Lancaster University for mid-infrared light emitting diode applications.
  • optimise the electronic and optical properties of type-II GaSb/GaAs quantum rings for intermediate band solar cells.
  • support the design and analysis of single photon sources operating at telecommunication wavelengths with the collaboration with University of Rome La Sapienza.

His research interests mainly involve modelling of photonic devices; e. g. solar cells, light emitting diodes, semiconductor lasers.
