	Band Gap Dependence on Cation Disorder in ZnSnN 2 Solar Absorber Tim D. Veal , Nathaniel Feldberg , Nicholas Quackenbush , Wojciech M. Linhart , David O. Scanlon , Louis Piper , Steven M. Durbin Advanced Energy Materials 5 (24) DOI: 10.1002/aenm.201501462 Open Access Show Abstract ▼ Abstract: The band gap of earth-abundant ZnSnN2 can be tuned between 1 and 2 eV by varying the growth conditions and resulting cation disorder. The optical absorption edges and carrier densities fall between model curves for cation-ordered orthorhombic and disordered wurtzite ZnSnN2. Hard X-ray photoemission spectra suggest different degrees of cation disorder from comparison with hybrid DFT-calculated densities of states.	Dec 2015
	Lithiation-Induced Dilation Mapping in a Lithium-Ion Battery Electrode by 3D X-Ray Microscopy and Digital Volume Correlation David S. Eastwood , Vladimir Yufit , Jeff Gelb , Allen Gu , Robert Bradley , Stephen J. Harris , Daniel J. L. Brett , Nigel P. Brandon , Peter Lee , Philip Withers , Paul Shearing Advanced Energy Materials 4 (4) DOI: 10.1002/aenm.201300506 Show Abstract ▼ Abstract: Recent advances in high-resolution 3D X-ray computed tomography (CT) allow detailed, non-destructive 3D structural mapping of a complete lithium-ion battery. By repeated 3D image acquisition (time lapse CT imaging) these investigations of material microstructure are extended into the fourth dimension (time) to study structural changes of the device in operando. By digital volume correlation (DVC) of successive 3D images the dimensional changes taking place during charge cycling are quantified at the electrode level and at the Mn2O4 particle scale. After battery discharging, the extent of lithiation of the manganese (III/IV) oxide grains in the electrode is found to be a function of the distance from the battery terminal with grains closest to the electrode/current collector interface having the greatest expansion (≈30%) and grains furthest from the current collector and closest to the counter electrode showing negligible dilation. This implies that the discharge is limited by electrical conductivity. This new CT+DVC technique is widely applicable to the 3D exploration of the microstructural degradation processes for a range of energy materials including fuel cells, capacitors, catalysts, and ceramics	Mar 2014
I16-Materials and Magnetism	The Nanoscale Morphology of a PCDTBT:PCBM Photovoltaic Blend Paul Staniec , Andy Parnell , Alan Dunbar , Hunan Yi , Andrew Pearson , Paul Hopkinson , Tao Wang , Christy Kinane , R Dagliesh , Athene Donald , Anthony Ryan , Ahmed Iraqi , Richard Jones , David Lidzey Advanced Energy Materials DOI: 10.1002/aenm.201100144 Show Abstract ▼ Abstract: Neutron reflectivity and X-ray scattering have been used to characterise the structure of photovoltaic optimised PCDTBT:PCBM (1:4) blend films. A negative gradient of the PCBM forms spontaneously upon film casting a fortuitous structure that is well matched for efficient charge extraction. Mild thermal annealing at 70 °C does not significantly modify the film structure, and any improvement in device efficiency is likely to be through the removal of trapped casting solvent.	Apr 2011
