Atomically precise manufacturing (APM) is a key technique that involves the direct control of atoms in order to manufacture products or components products. It has been developed most successfully using scanning probe methods and received particular attention for developing atom scale electronics with focus on silicon-based systems. This review captures development silicon atom-based divided into several sections will cover characterization manipulation surfaces tunneling microscopy atomic...
Engineering low-band-gap π-conjugated polymers is a growing area in basic and applied research. The main synthetic challenge lies the solubility of starting materials, which precludes advancements field. Here, we report an on-surface synthesis protocol to overcome such difficulties produce poly(p-anthracene ethynylene) molecular wires on Au(111). To this aim, quinoid anthracene precursor with =CBr
Abstract Bare silicon dimers on hydrogen-terminated Si(100) have two dangling bonds. These are atomically localized regions of high state density near to and within the bulk band gap. We studied bare as monomeric units. Silicon dimer wires much more stable than composed individual Dimer 1 5 were intentionally fabricated characterised by STM techniques combined with functional theory provide detailed insights into geometric electronic structure. Structural dynamic qualities displayed short...
The single molecule magnet (SMM) bis(phthalocyaninato)terbium (III) (TbPc$_2$) has attracted steady research attention as an exemplar system for realizing molecule-based spin electronics. In this paper, we report on the spontaneous formation of Tb$_2$Pc$_3$ species from TbPc$_2$ precursors via sublimation in ultrahigh vacuum (UHV) onto Ag(111) surface. molecules surface are inspected using combined scanning tunneling (STM) and non-contact atomic force microscopies (nc-AFM) at 5 Kelvin....
Understanding the nucleation and growth kinetics of thin films is a prerequisite for their large-scale utilization in devices. For self-assembled molecular phases near thermodynamic equilibrium nucleation–growth kinetic models are still not developed. Here, we employ real-time low-energy electron microscopy (LEEM) to visualize phase transformation induced by carboxylation 4,4′-biphenyl dicarboxylic acid on Ag(001) under ultra-high-vacuum conditions. The initial (α) transformed (β)...
Abstract Engineering low‐band‐gap π‐conjugated polymers is a growing area in basic and applied research. The main synthetic challenge lies the solubility of starting materials, which precludes advancements field. Here, we report an on‐surface synthesis protocol to overcome such difficulties produce poly( p ‐anthracene ethynylene) molecular wires on Au(111). To this aim, quinoid anthracene precursor with =CBr 2 moieties deposited annealed 400 K, resulting anthracene‐based polymers....
We investigate the possibility of functionalizing Au tips by N2O molecules deposited on a Au(111) surface and their further use for imaging with submolecular resolution. First, we characterize adsorption species means atomic force microscopy CO-functionalized density functional theory (DFT) simulations. Subsequently devise method attaching single to metal tip apex benchmark its high-resolution spectroscopic capabilities using FePc molecules. Our results demonstrate feasibility imaging....
Abstract Atomic scale defects significantly affect the mechanical, electronic, and optical properties of π‐conjugated polymers. Here, isolated atomic‐scale are deliberately introduced into a prototypical anthracene‐ethynylene polymer, its local density states is carefully examined on atomic to show how individual modify inherent electronic magnetic this one‐dimensional systems. Scanning tunneling force microscopy experiments, supplemented with functional theory calculations, reveal existence...

We report on the formation of fullerene-derived nanostructures Au(111) at room temperature and under UHV conditions. After low-energy ion sputtering fullerene films deposited Au(111), bright spots appear herringbone corner sites when measured using a scanning tunneling microscope.

Atomar präzise Ethinylen-verbrückte Anthracen-Polymere wurden auf Edelmetall-Substraten aus Chinoid-Präkursoren, die mit =CBr2-Gruppen ausgestattet sind, hergestellt. In ihrer Zuschrift S. 6631 zeigen J. Björk, P. Jelínek, N. Martín, D. Écija et al., dass Abscheidung dieser Präkursoren Au(111) bei Raumtemperatur und anschließendes Erhitzen über 400 K zur Bildung langer defektfreier eindimensionaler Polymere durch Homokupplung Aromatisierung führt.
