WebNitride hydrides are a largely unexplored class of materials with promising applications in solid-state hydrogen fuel cells. Here, we use first-principles calculations to characterize defects and ionic mobility in Sr2LiH2N (SLHN), a nitride hydride that has previously been synthesized but has not yet been evaluated as a hydride conductor. Calculating defect … Web14 de out. de 2024 · The sign of the lattice mismatch, minus (−) or plus (+), is also important. For example, it was determined that the thickness of the pseudomorphous growth, i.e. the critical thickness h c, is larger when the lattice mismatch is negative and the film is growing under tensile strain than in the case of a positive lattice mismatch when the layer is …
