Volatile Memristive Devices With Tunable Temporal Dynamics For Event‐Based Sensing

Advanced Materials, EarlyView.
Tunable volatile memristive devices can serve various neural‐inspired tasks that require different time windows of information retention. The ionic‐based volatility of the presented Pt/a‐STO/TaOx/Ta device stack can be reproducibly and controllably tuned in multiple ways.

Connectivity Times for Mobile D2D Networks [PDF]

2018 IEEE International Conference on Communications (ICC), 2018
Connectivity questions for mobile D2D networks are often approached by considering steady state performance metrics. This is due to the difficulty in handling a finite time horizon with random mobility. Hence, in this paper we create a framework to evaluate connectivity time in closed form over a finite time horizon for mobile devices. The basic metric

TiO6 as a Compensatory Structural Unit in Co‐Free, High‐Ni Layered Oxide for Durable Lithium‐Ion Batteries

Advanced Science, EarlyView.
Ti substitution stabilizes Co‐free high‐Ni layered oxides through both structural and electronic effects. TiO6 octahedra act as compensatory structural units that help interrupt cooperative Jahn–Teller distortion and suppress detrimental phase transitions, while the electron‐withdrawing inductive effect of Ti stabilizes the oxygen lattice. As a result,

Lattice Disorder in CuI Enables Filament‐Free Transparent Memristors

Advanced Science, EarlyView.
Transparent Cu1‐xAgxI thin‐film memristors rely on internal ion transport to produce reversible resistive‐switching effects. Direct elemental characterizations observe obvious Cu and Ag redistribution driven by applied bias, proving mobile ions drive the device's resistive‐switching responses.
