SnSi nanocrystals of zinc-blende structure in a Si matrix
epitaxy, density functional theory, zinc-blende, Si–Sn alloy
A zinc-blende (sphalerite) crystallographic structure of SnSi nanocrystals in a Si matrix is revealed by transmission electron microscopy. The effect of compressive strain due to the matrix stabilizes the unusual zinc-blende structure of SnSi nanocrystals, as revealed by ab initio density-functional modeling.
