Nanoscale resistive switching in electrodeposited MOF Prussian blue analogs driven by K-ion intercalation probed by C-AFM
L. B. Avila, O. de Leuze, M. Pohlitz +12
K-ion intercalation in Prussian blue analogs (PBAs) is a well-established charge storage mechanism in potassium-ion batteries; here, we demonstrate that this same ion intercalation…
Model-derived conversion formula for real-time gas monitoring based on chemiresistive sensors
Fernando Massa Fernandes, Benoît Hackens
Chemiresistive gas sensors transduce gas adsorption into changes in the electrical resistance across a pair of electrodes connected by a sensitive layer of material. This type of s…
Elucidating different sensing mechanisms in oxidized PbS nanocrystals
Fernando M. Fernandes, Fouad El Haj Hassan, Sophie Hermans +1
In this work we provide an in-depth analysis of the sensing mechanisms of by lead-sulfide nanocrystals (PbS-NCs). A detailed model for the sorption mechanism is proposed,…
Fast hydrogen atom diffraction through monocrystalline graphene
Pierre Guichard, Arnaud Dochain, Raphaël Marion +5
We report fast atom diffraction through single-layer graphene using hydrogen atoms at kinetic energies from 150 to 1200 eV. High-resolution images reveal overlapping hexagonal patt…
Inter-flake transport and humidity response of Ti3C2Tx MXene at the nanoscale
Oriane de Leuze, Maxime Berthe, Sophie Hermans +1
Understanding charge transport in networks of two-dimensional crystals is essential for developing reliable applications such as chemiresistors or electromagnetic shields. For this…
Thermal transport mapping in twisted double bilayer graphene
Roop Kumar Mech, Alessandra Canetta, Yubin Huang +13
Two-dimensional (2D) materials have attracted significant interest due to their tunable physical properties when stacked into homo- and hetero-structures. Twisting adjacent layers…
