Fluorinated hybrid solid-electrolyte-interphase for dendrite-free lithium deposition
Nature Communications, 2020 Here the authors report a simple method to create a solid electrolyte interphase that is tightly anchored onto the surface of lithium metal anode. This artificial structure suppresses dead and dendrite Li and stores Li via formation of alloys, enabling ...

Si(Li) detectors with thin dead layers for low energy X-ray detection [PDF]
IEEE Transactions on Nuclear Science, 1991 Regions of incomplete charge collection, or dead layers, are compared for Si(Li) detectors fabricated with Au and Pd entrance-window electrodes. The dead layers were measured by characterizing the detector spectral response to X-ray energies above and below the Si K alpha absorption edge.
