• Radiative signatures of the jet launching region in astronomical objects 

  O' Riordan, Michael (University College Cork, 2018)

  Relativistic jets are observed in a wide range of accreting black hole systems, from stellar-mass black holes in X-ray binaries (XRBs), to supermassive black holes in active galactic nuclei (AGN). However, despite decades ...
• Thermoelectric properties of PbTe-based materials driven near the ferroelectric phase transition from first principles 

  Murphy, Aoife Rose (University College Cork, 2017)

  The thermoelectric figure of merit, ZT, is a dimensionless parameter used to characterise the efficiency of a thermoelectric material. One of the most common techniques to improve ZT is to suppress lattice thermal conductivity ...
• Monolithic integration of photonic devices for use in a regrowth-free coherent WDM transmitter 

  Kelly, Niall (University College Cork, 2017)

  In this communication age, consumer internet traffic continues to grow at an exponential rate year on year. As a result, networks need to be continually upgraded to keep up with ever increasing bandwidth demands. Diverse ...
• Low-linewidth optical comb sources based on gain-switched lasers 

  Alexander, Justin K. (University College Cork, 2017)

  As the number of internet users continues to grow, along with the increase in bandwidth demanding services, the optical communications network struggles to keep up. Upgrading the optical fibre network is a costly endeavour, ...
• A study of the elastic and electronic properties of III-nitride semiconductors 

  Tanner, Daniel Stephen Patrick (University College Cork, 2017)

  In this work, a theoretical study of the elastic and electronic properties of III-N semiconductors is made. Particular attention is given to wurtzite quantum wells (QWs) based on the technologically important InxGa1_xN ...
