Shimul Kanti Nath, Sanjoy Kumar Nandi, Xiao Sun, Sujan Kumar Das, Bin Gong, Nicholas J. Ekins-Daukes, Deepak Mishra, Mahesh P. Suryawanshi, William D. A. Rickard, Songyan Yin, Michael P. Nielsen, Robert G. EllimanThree-dimensional ToF-SIMS uncovers oxygen retention in the top Pt electrode and unexpected Pt migration into the oxide. This coupled exchange reshapes filament chemistry and may critically influence memristor reliability.
