These agglomerates, consisting of smaller grains separated by ridges, resemble the surface morphology of 300 nm thick polycrystalline Sb2S3 films grown via thermal evaporation and annealed for 10 min at 300 °C in N2 [35], and that of metal halide perovskites obtained by Volmer–Weber growth

• length for the growth species at the surface is larger and nucleation occurs more separated in space (similar to the Volmer–Weber growth). Nanoflakes can grow subsequently from these nucleation sites leading to the formation of straight CNWs. This process is similar to the model suggested by Kondo and co

• relatively low and cohesion of Ag adatoms dominates to induce Volmer–Weber growth. During the deposition process, clusters of silver adatoms behave as liquid droplets with high wetting angle. The measured height of these islands was 18.6 nm in the case of depositing an equivalent of 12 nm thick silver layer

• deposition of silver on a hot substrate results in weaker wetting. Thus, even though germanium was utilized, silver formed islands during the deposition process – a transition from Frank–van der Merve to Volmer–Weber growth mode. This resulted in increasing the rate of the segregation process, since

Stranski–Krastanov growth is obtained with αu(i < ic) = 0, αd(i ≤ ic) >> 1, αu(i ≥ ic) >> 1 and αd(i > ic) = 0, where ic is the critical thickness above which 3D islands form.

Conclusion Films formed by codeposition were similar to those formed by LBL in that they were composed of nanocrystallites and were not conformal films produced by a van der Merwe growth mechanism.

• . Such a spherical morphology suggests a Volmer–Weber growth mechanism of Pd. Such a formation of 3D islands is due to the high difference of surface energies between the metallic Pd and the oxidized support [39][40]. The formation of 3D islands can also be supported by the H-hfac ligands that are
