WebThe large grain and preferential growth of Sb2S3 thin film were implemented by crystallization and cooling techniques, respectively. The corresponding devices were gradually optimized with a power conversion efficiency of similar to 3.5%, almost three times of planar devices fabricated by vacuum method. Web1 Apr 2024 · In this study, a magnetron-sputtered Cu-Nb nanolayered composite having an amorphous interface between Cu and Nb with a high density of aligned growth twins in Cu is subjected to severe surface deformation. The material is loaded using indentation and cyclic shear under tribological testing.
Web7 Apr 2008 · The alloys function as a growth catalyst and provide Mo-rich chemical environments during the growth, which guide the formation of pentagon-heptagon defects with Mo-Mo homo-elemental bond (Mo 5 7) by yield > 95 %. In particular, we found that GBs with high tilt angle ( θt > 34°) relieve strains by deformation-twining, instead of forming a ... WebPrevious studies have established that pentacene films deposited on silicon oxide consist of a substrate-induced "thin-film" phase, with the bulk phase of pentacene detected in thicker films only. We show that the bulk phase nucleates as early as the first monolayer, and continues to nucleate as film growth progresses, shadowing the growth of the thin-film …

Grain …
WebThe structural and chemical analysis revealed that Cu was very effective in promoting the transformation to the L1 0 ordered phase and to suppress the grain growth of the L1 0 ordered phase when films were annealed at 400 °C-700 °C in vacuum. During the annealing, Cu atoms diffused onto the film surface, probably yielding many defects remain ...
