DESCRIPTION:Speaker: Sam Stranks\nhosted by Zhanybek Alpichshev\nAbstract: 
 Halide perovskites are generating enormous excitement owing to their use i
 n high-performance device platforms including solar cells\, LEDs\, X-ray d
 etectors and quantum emitters. However\, there remains performance losses 
 and operational instability pathways in devices that limit their true pote
 ntial. This talk will outline a series of multimodal microscopy approaches
  to unveil nanoscale insights into perovskite devices\, providing detailed
  information about the impact of defects on both performance and stability
 . Correlations between local structural and carrier trapping measurements 
 reveal nanoscale sites that act as carrier traps and sites that seed degra
 dation. At low temperature\, these same defects also show fascinating quan
 tum emission behaviour. I will also show our latest understanding on local
  octahedral correlations that impact optoelectronic properties. Finally\, 
 I will demonstrate how controlled layer-by-layer epitaxial vapour growth l
 eads to high-quality 2D/3D heterojunctions\, making the building blocks fo
 r tuneable multi-quantum well structures.
