Fig. 1

A Device schematic showing various layers in the stack. B SRIM simulations showing proton straggling for 0.06 MeV (cyan) and 1.0 MeV (green) protons. Vacancy profiles are overlaid on the straggling images. NIEL and IEL profiles for the various irradiation scenarios considered are shown in (C) and (D). By selecting the two radiation conditions (energy and fluence) shown with dashed lines in (C), the NIEL created in each cell is the same, whereas the IEL increases up to a factor of 27.5 greater for increasingly higher energy dosing as shown in (D). This enables us to tune the IEL/NIEL ratio. Source data are provided as a Source Data file.
