Electron-hole diffusion lengths > 175 μm in solution-grown CH3NH3PbI3 single crystals
TL;DR: It is found that the diffusion lengths in CH3NH3PbI3 single crystals grown by a solution-growth method can exceed 175 micrometers under 1 sun (100 mW cm−2) illumination and exceed 3 millimeters under weak light for both electrons and holes.
Journal ArticleDOI
In Situ Quantification and Visualization of Lithium Transport with Neutrons
TL;DR: Using in situ neutron depth profiling (NDP), the onset of lithiation in a high-capacity Sn anode is probed and the enrichment of Li atoms on the surface followed by their propagation into the bulk is visualized.
Journal ArticleDOI
Investigation by slow positron beam of defects in CLAM steel induced by helium and hydrogen implantation
TL;DR: In this article, the authors analyzed the Doppler broadening of gamma-rays generated in positron annihilation, showing that the induced defect size has obvious variation with depth, taking values that interpolate between surface and bulk values, and depend mainly on helium ion fluences.
Journal ArticleDOI
He and H-implanted CLAM steel investigated by positron-annihilation spectroscopy
TL;DR: The distribution and nature of defects induced by H ion, He ion, and mixed-beam H and He ion implantation in China low-activation martensitic (CLAM) steel were studied by positron-annihilation spectroscopy.
Journal ArticleDOI
Neutron irradiation effects on gallium nitride-based Schottky diodes
TL;DR: In this paper, the effect of fast versus thermal neutrons on metal-GaN Schottky diodes was investigated using depth-resolved cathodoluminescence spectroscopy (DRCLS) and X-ray photoemission spectrograms.
