Enhanced conductivity in pulsed laser deposited Ce0.9Gd0.1O2−δ/SrTiO3 heterostructures

Electrochemical stability of (La,Sr)CoO3−δ in (La,Sr)CoO3−δ/(Ce, Gd)O2−δ heterostructures

“…Satellite peaks of CGO and LSC are visible at higher and lower angles with respect to the main reflection peaks, indicating high-quality of the heterostructures. 16,18,48,49 The values of full width at half maximum (FWHM) are between 0.5°<2 < 1.3° (Figure 1b), suggesting a high degree of crystallinity and low structural and microstructural mosaic disorder in the films. Especially, the crystallinity of the films improves by decreasing N and increasing the thickness This effect is likely due to the theoretical mismatch between CGO and LSC is 0.92%.…”

When two become one: An insight into 2D conductive oxide interfaces

“…In Kant et al, we used highly coherent CGO thin films of 250 nm on buffered MgO(001)/STO substrates to evaluate the effect of strain in highly coherent interface using several thicknesses at STO buffer (10, 20 and 50 nm) [117,118]. Fig.…”

Study on Zinc Oxide-Based Electrolytes in Low-Temperature Solid Oxide Fuel Cells

“…This partly manifests that the migration of ions at the grain boundary is less resistive in the composite. We attributed this phenomenon to the heterophasic interfacial conduction effect at semiconductor oxide/ionic conductor oxide interface regions in hetero-structured composite material [19,50]. Such behavior has been reported in many semiconducting ionic systems, such as La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3−δ -Ca 0.04 Ce 0.8 Sm 0.16 O 2−δ (LSCF-SCDC), YSZ-SrTiO 3 , and CoFe 2 O 4 -GDC [15,20,51].…”
