Wednesday 1 December; Delft, Nanoscience Seminar Richard Warburton 'Single spins in InGaAs quantum dots'



Time: 16:00 hrs

Location: Zaal E, TNW, Delft


The search for a highly coherent electronic spin in the solid state has led most spectacularly to the NV colour centre in diamond. Have self-assembled quantum dots, InGaAs in GaAs, been left behind? The advantages of self-assembled quantum dots are considerable - strong optical transition, heterostructure technology, post-growth processing techniques - but so far the spin coherence has been at best modest. This talk will present some possible ways to out fox the decoherence processes in a semiconductor with the goal of creating a highly coherent spin.
