Solid-state dewetting of Pt on (100) SrTiO3

Grain growth: The key to understand solid-state dewetting of silver thin films

“…This diffusion was found to depend on the surrounding atmosphere [6,9]. Atiya et al [16,17] showed that the dewetting of platinum thin films supported on SrTiO 3 (100) is clearly impacted by the orientation of the substrate. They observed that grains having specific crystallographic orientations play an important role in hole propagation morphology and kinetics.…”

“…More recently, the role of grains in dewetting of polycrystalline layers started to be discussed in the literature [10,15,16,17]. In this regard, new insight on the role of grains and dewetting in general was brought by in situ techniques, naturally allowing for more accurate kinetic data compared to interrupted annealing [18] Kosinova et al [6,9] studied hole propagation by in situ Atomic Force Microscopy (AFM).…”

Engineering crystalline Au nanoparticles of anisotropic shape in epitaxially grown high-index SrTiO3

“…The growing number of LSPR potential application areas is based on rapid advances in particle fabrication. There are different possibilities to produce particles-using chemical syntheses [10], lithography [7,8], dewetting processes [11][12][13], or self-organized preparation within matrices [14][15][16][17]. All of these methods allow fabricating different kinds of particles but with different complexity.…”

“…It can be used for a variety of applications such as for optic-electronic devices [18] and high-Tc superconducting materials [19]. In [13], for instance the solid state dewetting process of thin continuous platinum (Pt) films-also an fcc metal like Au-on STO substrates was investigated, respectively, the formation of particles and of an interfacial phase at 1150°C. The change of material properties using amorphous or crystalline matrices such as SiO 2 or TiO 2 was studied for instance in [12,16,[20][21][22] in order to investigate a variation in plasmonic properties of the particle/layer system.…”

Optical characterization of YBa2Cu3O7− thin film modified gold nanoparticles

“…In order to overcome the complicated and time consuming multiple fabrication steps, a preparation of particles directly at the surface would reduce preparation time and costs. For example, nanoparticles can be prepared directly at the substrate surface by a dewetting process of thin metal films [1][2][3][4]. Furthermore, in recent years different multilayer systems have been manufactured with various physical vapor deposition (PVD) methods to produce Au or Ag nanoparticles on surfaces.…”
