N-Heterocyclic Carbenes on a III-V Semiconductor: From Chain Formation to Ordered Monolayers.
Article in Angewandte Chemie (International ed. in English), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
N-Heterocyclic carbenes (NHCs) are established ligands for various surfaces, known for their strong binding, ability to form self-assembled monolayers, and modular structure. However, semiconductor surface modification with NHCs is still in its infancy despite its technological importance. Although previous studies focused on silicon, III-V compound semiconductors offer direct bandgaps and high electron mobilities, making them ideal for (opto-)electronics. This study examines the adsorption of different NHCs on GaAs, a prototypical III-V material, using scanning tunneling microscopy, density functional theory, X-ray photoelectron spectroscopy, low-energy electron diffraction, and reflectance anisotropy spectroscopy. Covalent binding to the surface and the formation of well-ordered NHC monolayers are observed, along with exceptionally large work function reductions. The unique structural features of NHCs enable precise control over film structure, ordering, and electronic properties.
