Aurophilicity is a well-known phenomenon in structural gold chemistry and is found in many crystals of Au(I) complexes. However, these attractive dispersion forces between and within complexes containing Au(I) moieties have not been well studied in ultrathin films. In this paper, we elucidate the interaction of chlorido(2-naphthyl isonitrile)gold(I) on and with Au(110) surfaces. Already during physical vapor deposition, the condensation of ultrathin films is monitored by photoelectron emission microscopy (PEEM) and by incremental and spectrally resolved changes in the optical reflectance (DDRS). Additional structural data obtained by STM and LEED reveal that the "crossed swords" packing motif known from the bulk is also present in thin films. The molecular arrangement changes several times during thin-film deposition.

Van der Waals (vdW) dielectrics are extensively employed to enhance the performance of 2D electronic devices. However, current vdW dielectric materials still encounter challenges such as low dielectric constant (κ) and difficulties in synthesizing high-quality single crystals. 2D rare-earth oxyhalides (REOXs) with exceptional electrical properties present an opportunity for the exploration of novel high-κ dielectrics.

Freestanding networked nanoparticle (NP) films hold substantial potential due to their high surface areas and customizable porosities. However, NPs with high surface energies and heterogeneous sizes or shapes present considerable challenges as they tend to aggregate, compromising their structural integrities. In this study, we report the scalable fabrication of ultrathin, bicontinuous, and densely packed carbon NP films via Pickering emulsion-mediated interfacial assembly.

Carbon fiber (CF) has been widely used in aerospace, military, infrastructure, sports, and leisure fields owing to its excellent mechanical properties, superior corrosion and friction resistances, excellent thermal stability, and lightweight. However, the ultrablack appearance derived from the extremely strong absorption of light throughout the entire visible region makes it difficult to satisfy the aesthetic and pleasurable demands of the colorful world and limits their applications in a broader field. Herein, inspired by the , a double-layer ultrathin AlO/TiO composite structure was fabricated on CFs by the atomic layer deposition method.

For weakly interacting adsorbate/substrate systems, the integer charge transfer (ICT) model describes how charge transfer across interfaces depends on the substrate work function. In particular, work function regimes where no charge transfer occurs (vacuum level alignment) can be distinguished from regions where integer charge transfer by electron tunneling from substrate to adsorbate or vice versa takes place (Fermi level pinning). While the formation of singly integer charged molecular anions and cations of organic semiconductors on various substrates has been well described by this model, the double integer charging regime has so far remained unexplored and experimentally elusive.
