  "abstract": "Substrate strain offers a route to control deformation in supported metallic nanoparticles, provided that interfacial coupling transmits the imposed loading into the particle. We assess this feasibility using five static Cu/Si(111) configurations spanning 0-2% biaxial tensile substrate strain. A 211,288-atom Cu particle is supported by a nominally 50 x 50 x 20 nm Si slab with its bottom 1 nm fixed, using the Jelinek modified embeddedatom potential. Relative to the relaxed supported 0% state, Cu-only local fits reveal heterogeneous, anisotropic deformation: particle-wide mean hydrostatic strain is negative at every nonzero loading, from -3.12 x 10 -6 to -8.84 x 10 -6 , while the upper-particle mean varies nonmonotonically. Simulated Bragg CDI of Cu( 111), obtained by inversion of known complex atomic scattering amplitudes, maps loading-dependent projected displacement and strain. The combined atomistic and Bragg CDI representations provide strong preliminary support for the feasibility of substrate-mediated strain transfer in this idealized system and identify spatial signatures for experimental investigation. Experiments remain indispensable to confirm transfer in real Cu/Si(111) nanoparticles and determine its magnitude.",
