Electrochemical dynamics of nanoscale metallic inclusions in dielectrics
Yuchao Yang,Peng Gao,Peng Gao,Linze Li,Xiaoqing Pan,Stefan Tappertzhofen,Shinhyun Choi,Rainer Waser,Ilia Valov,Wei Lu +9 more
TL;DR: It is demonstrated that nanoscale inclusions in dielectrics dynamically change their shape, size and position upon applied electric field, revealing the microscopic origin behind resistive switching, and providing general guidance for the design of novel devices involving electronics and ionics.
Journal ArticleDOI
Nanobatteries in redox-based resistive switches require extension of memristor theory
Ilia Valov,Eike Linn,Stefan Tappertzhofen,Sebastian Schmelzer,J. van den Hurk,Florian Lentz,Rainer Waser +6 more
TL;DR: It is shown on both a theoretical and an experimental level that nanoionic-type memristive elements are inherently controlled by non-equilibrium states resulting in a nanobattery.
Journal ArticleDOI
Beyond von Neumann—logic operations in passive crossbar arrays alongside memory operations
TL;DR: It is demonstrated here that 14 of 16 Boolean functions can be realized with a single BRS or CRS cell in at most three sequential cycles, making logic-in-memory applications feasible.
Journal ArticleDOI
Generic Relevance of Counter Charges for Cation-Based Nanoscale Resistive Switching Memories
TL;DR: It is demonstrated that the formation of metallic cations proceeds in parallel to reduction of moisture, supplied by the ambient, and this results contribute to the microscopic understanding of the resistive switching phenomena in cation-based ReRAMs.
Journal ArticleDOI
Switching kinetics of electrochemical metallization memory cells
TL;DR: This study provides new insights into the understanding of the limiting electrochemical processes determining the switching kinetics of ECM cells.
