Engineering Synaptic Dynamics in Ag-Modified TaO Memristive Devices
R. Leal Martir, W. Quiñonez, A. J. T. van der Ree +4
Engineering not only the magnitude but also the dynamics of synaptic weight updates is an important challenge for memristive neuromorphic hardware. Here, we show that Ag modificati…
Device-area selection of memristive transport regimes in epitaxial -based ferroelectric devices
Priscila A. Tapia Presas, Lautaro Galarregui, Wilson Román Acevedo +5
Ferroelectric memristive devices based on hafnia are promising systems for neuromorphic electronics, yet the interplay between polarization-modulated resistive changes and defect-m…
Oxygen vacancy engineering in pulsed laser deposited BaSnO thin films on SrTiO
Wilson Román Acevedo, Myriam H. Aguirre, Beatriz Noheda +1
We demonstrate the tunability of oxygen content in pulsed laser deposition (PLD)-grown barium stannate (BaSn, BSO) thin films by precisely controlling the background oxygen pr…
Electrically-driven control of nanoscale chemical changes in amorphous complex oxide memristive devices
Wilson Román Acevedo, Myriam H. Aguirre, Diego Rubi
Our study demonstrates that strong cationic segregation can occur in amorphous complex oxide memristors during electrical operation. With the help of analytic techniques, we observ…
