Unveiling the interaction mechanisms of electron and X-ray radiation with halide perovskite semiconductors using scanning nano-probe diffraction
Jordi Ferrer Orri, Tiarnan A. S. Doherty, Duncan Johnstone +5
The interaction of high-energy electrons and X-ray photons with soft semiconductors such as halide perovskites is essential for the characterisation and understanding of these opto…
Local Nanoscale Defective Phase Impurities Are the Sites of Degradation in Halide Perovskite Devices
Stuart Macpherson, Tiarnan A. S. Doherty, Andrew J. Winchester +12
Halide perovskites excel in the pursuit of highly efficient thin film photovoltaics, with power conversion efficiencies reaching 25.5% in single junction and 29.5% in tandem halide…
Scanning electron diffraction tomography of strain
Robert Tovey, Duncan N. Johnstone, Sean M. Collins +4
Strain engineering is used to obtain desirable materials properties in a range of modern technologies. Direct nanoscale measurement of the three-dimensional strain tensor field wit…
Density-based clustering of crystal orientations and misorientations and the orix python library
Duncan N. Johnstone, Ben H. Martineau, Phillip Crout +2
Crystal orientation mapping experiments typically measure orientations that are similar within grains and misorientations that are similar along grain boundaries. Such (mis)orienta…
Ultrafast long-range energy transport via light-matter coupling in organic semiconductor films
Raj Pandya, Richard Y. S. Chen, Qifei Gu +29
The formation of exciton-polaritons allows the transport of energy over hundreds of nanometres at velocities up to 10^6 m s^-1 in organic semiconductors films in the absence of ext…
Crystallographic relationships of T-/S-phase aggregates in an Al-Cu-Mg-Ag alloy
Jonas K. Sunde, Duncan N. Johnstone, Sigurd Wenner +3
T-(Al20Cu2Mn3) phase dispersoids are important for limiting recovery and controlling grain growth in Al-Cu alloys. However, these dispersoids can also reduce precipitation hardenin…
