2 Δεκ 2020 · This showcases how ionic defect equilibria influence the electronic charge transfer in confined oxide systems already at temperatures much lower than observed in the bulk and how the balance of electronic and ionic species is jointly responsible for the rich physics of oxide heterostructures.
5 Αυγ 2024 · 2.2 ECMs for Oxide Layers and Charge Transfer Reactions. The above-discussed ECMs are directly applicable to describe the response of electrodes without charge transfer reactions and without oxide coverage.
17 Ιουν 2022 · In this work, we use such a scheme to study how the NQEs and the H-bond network affect the photoexcited charge transfer at the CH 3 OH/TiO 2 interface. The interface is chosen as a prototypical system for the following reasons. TiO 2 has important applications in photocatalysis and photovoltaics.
6 Ιαν 2020 · Constructing a pathway for mixed ion and electron transfer reactions for O 2 incorporation in Pr 0.1 Ce 0.9 O 2−x. Di Chen, Zixuan Guan, Dawei Zhang, Lena Trotochaud, Ethan Crumlin,...
1 ημέρα πριν · The photocathode was obtained by depositing catalyst ink (average catalyst loading of 2 mg cm −2) by drop-casting on carbon felt (CF) with an area of 5 cm 2, and then drying in an oven at 60 °C for 12 h. A home-made liquid zinc-air battery with a polished Zn foil anode (0.25 mm thickness) and a photocathode air electrode was used to conduct ...
Beyond electronic phenomena, ionic charge-transfer also yields new opportunities to tailor and functionalize the ionic properties of oxide interfaces: by forcing charge-transfer to take place primarily via exchange of ions from one side of the interface to the other, one may tailor the ionic conductivity along the interface (Fig. 1b).
In this paper, we propose a simple scheme to predict band alignment and charge transfer in complex oxide interfaces. For semiconductor heterostructures, band-alignment rules like the well-known Anderson or Schottky-Mott rule are based on comparison of the work function or electron affinity of the bulk components.
