a Three-dimensional schematic of a metal/h-BN/metal structure. b Cross-sectional TEM image of the multilayer CVD-grown h-BN stack, c top view optical microscope image of an array of metal/h-BN/metal memristors. d Forming plots of several Au/Ti/h-BN/Au devices, and the (e) reset and (f) set plots showing a few non-volatile bipolar RS in a single device. g Cross-sectional TEM image of the multilayer mechanically exfoliated h-BN stack, h top view optical microscope image of a metal/h-BN/metal memristor, i forming plot of the device corresponding to (g), and j topographic AFM map after the spot showing irreversible breakdown by material removal (i.e., crater formation).
