Confined in a molecular corral: A supramolecular network changes the mechanism by which underpotential deposition (UPD) of copper proceeds on a gold electrode modified by a self-assembled monolayer (SAM). Lateral diffusion of Cu adatoms is suppressed between adjacent cells of a network/SAM hybrid structure. Instead, UPD occurs by direct deposition into the SAM filled pores of the network, where the Cu adatoms are confined.

Article Synopsis
  • Self-intercalation in two-dimensional (2D) materials can create ultrathin covalently bonded materials, offering a new avenue for studying quantum-confined materials with multifunctional capabilities.
  • Understanding the synthesis mechanisms of these self-intercalated 2D materials at the atomic scale is challenging, but the authors successfully synthesized ic-2D thin films from transition metal dichalcogenides (TMDCs) using thermal annealing inside an electron microscope.
  • Their findings show that the self-intercalation process is influenced by both thermodynamic and kinetic factors, allowing for precise control over the arrangement and properties of the resulting materials, which could lead to advancements in their practical applications.

Structure and Defect Identification at Self-Assembled Islands of CO Using Scanning Probe Microscopy.

Understanding how carbon dioxide (CO) behaves and interacts with surfaces is paramount for the development of sensors and materials to attempt CO mitigation and catalysis. Here, we combine simultaneous atomic force microscopy (AFM) and scanning tunneling microscopy (STM) using CO-functionalized probes with density functional theory (DFT)-based simulations to gain fundamental insight into the behavior of physisorbed CO molecules on a gold(111) surface that also contains one-dimensional metal-organic chains formed by 1,4-phenylene diisocyanide (PDI) bridged by gold (Au) adatoms. We resolve the structure of self-assembled CO islands, both confined between the PDI-Au chains as well as free-standing on the surface and reveal a chiral arrangement of CO molecules in a windmill-like structure that encloses a standing-up CO molecule and other foreign species existing at the surface.

Quantum-Confined Lifshitz Transition on Weyl Semimetal -MoTe.

Adsorption of alkali atoms onto material surfaces is widely utilized for controlling electronic properties and is particularly effective for two-dimensional materials. While tuning the chemical potential and band gap and creating quantum-confined states are well established for alkali adsorption on semiconductors, the effects on semimetallic systems remain largely elusive. Here, utilizing angle-resolved photoemission spectroscopy measurements and density functional theory calculations, we disclose the creation of two-dimensional electron gas and the quantum-confined Lifshitz transition at the surface of a Weyl semimetal -MoTe by potassium adsorption.

Hybrid DFT calculations are employed to compare the adsorption and stabilization of Cu, Ag, and Au atoms on graphitic CN and on the heterojunction formed by g- CN and TiO. While Cu and Ag can be strongly chemisorbed in form of cations on g- CN, Au is only weakly physisorbed. On g- CN/TiO, all coinage metal adatoms can be strongly chemisorbed, but, while Cu and Ag forms cations, Au form an Au species.
