Structure-driven analog optical control in ion-pumped SrFeO thin-film devices
Alicia Ruiz-Caridad, Paul Nizet, Francesco Chiabrera +4
Electrochromic devices (ECDs) offer a compelling route toward low-power, non-emissive optical modulators with nonvolatile states. However, their widespread implementation is hinder…
Investigating oxides by electrochemical projection of the oxygen off-stoichiometry diagram onto a single sample
Alexander Stangl, Alexander Schmid, Adeel Riaz +10
The oxygen stoichiometry is an essential key to tune functional properties of advanced oxide materials and thus has motivated numerous studies of the oxygen off-stoichiometry diagr…
Real time observation of oxygen diffusion in CGO thin films using spatially resolved Isotope Exchange Raman Spectroscopy
Alexander Stangl, Nicolas Nuns, Caroline Pirovano +4
The exploitation of advanced materials for novel energy, health and computing applications requires fundamental understanding of enabling physicochemical mechanisms, including ioni…
Analog control of electrical conductivity in La0.5Sr0.5FeO3-δ through oxygen deficiency induced magnetic transition
Paul Nizet, Francesco Chiabrera, Nicolau López-Pintó +9
Switchability of materials properties by applying controlled stimuli such as voltage pulses is an emerging field of study with applicability in adaptive and programmable devices li…
Solid-State Oxide-Ion Synaptic Transistor for Neuromorphic Computing
Philipp Langner, Francesco Chiabrera, Nerea Alayo +5
Neuromorphic hardware facilitates rapid and energy-efficient training and operation of neural network models for artificial intelligence. However, existing analog in-memory computi…
Optoionic Impedance Spectroscopy (OIS): a model-less technique for in-situ electrochemical characterization of mixed ionic electronic conductors
Paul Nizet, Francesco Chiabrera, Yunqing Tang +5
Functional properties of mixed ionic electronic conductors (MIECs) can be radically modified by (de)insertion of mobile charged defects. A complete control of this dynamic behaviou…
