Here, we propose an approach for controlling the layer thickness and crystallographic stacking sequence of multilayer graphene films at the wafer scale via Cu-Si alloy formation using direct chemical vapour deposition. C atoms are introduced by tuning the ultra-low-limit CH 4 concentration to form a SiC layer, reaching one to four graphene ...
28. Juli 2022 · a) Release of the freestanding oxide membranes (yellow, red) by dissolving the sacrificial layer (blue), b) stack of freestanding films, c) twisting the vertically stacked films. Although many novel functionalities have been recently discovered in the freestanding oxide membranes, [ 17 , 19 , 22 - 26 ] the assembling and stacking of these oxide thin films directly into heterostructures has not ...
15. Apr. 2022 · The optical constants of films (type 1–3) were measured in the wavelength range from 400 to 1600 nm (Fig. 1b,c). Film type4 was not investigated, because its carrier concentration was too high ...
11. Aug. 2014 · Cadmium telluride (CdTe) is a p-type semiconductor used in thin-film solar cells. To achieve high light-to-electricity conversion, annealing in the presence of CdCl2 is essential, but the underlying mechanism is still under debate. Recent evidence suggests that a reduction in the high density of stacking faults in the CdTe grains is a key process that occurs during the chemical treatment. A ...
3. Apr. 2015 · A novel nanoparticle-stacking thin film (NPSTF) of Pt-Ni alloy for highly active oxygen reduction reaction (ORR) electrocatalyst was synthesized.
A novel nanoparticle-stacking thin film (NPSTF) of Pt-Ni alloy for highly active oxygen reduction reaction (ORR) electrocatalyst was synthesized. The Pt mass activity of the synthesized Pt-Ni NPSTF were 10-fold higher than commercial carbon-supported Pt catalysts. The remarkable ORR activity enhancement of the Pt-Ni NPSTF was attributed to the modified electronic properties of the surface Pt ...
1. März 2024 · The film's luminous modulation increased from −2.05 % to + 1.86 %, and its solar modulation increased to 8.35 % with luminous transmittance of 57.18 % at 30 °C, which was the best experimental result reported for a single layer film structure of the same thickness. Also, this study offered a new approach for improving the relationship between luminous transmittance and solar modulation ...
