We report on the self-assembly of linear three-ring aromatic thiols on Au(111)/mica substrates. Our study examines terphenylthiol (TPT) derivatives with distinct terminal groups −F (FTPT), −CF 3 (CF 3 TPT) and −NO 2 (NTPT) as well as a pyridinebiphenyl (PyBPT) compound. Using complementary surface science…

Surface enhanced Raman spectroscopy (SERS) is an established technique for specific detection of fingerprint spectra of molecules at lowest concentrations. In particular, the application of silver‐based SERS substrates is promising due to their favorable physical properties for enhancing Raman signals.…
Lateral heterostructures built of monolayers of transition-metal dichalcogenides host a thin one-dimensional interface exhibiting a large energy offset. Recently, the formation of spatially separated charge-transfer (CT) excitons at the interface has been demonstrated, but their impact on technologically…

We report on the fabrication of a boron-based two-dimensional (2D) material via electron irradiation-induced cross-linking of carborane self-assembled monolayers (SAMs) on crystalline silver substrates. The SAMs of 1,2-dicarba- closo -dodecarborane-9,12-dithiol ( O9,12 ) were prepared on flat crystalline…

Janus SeMoS monolayers (MLs) are synthetic 2D materials with unique electronic properties, as theory predicts, but their experimental exploration has been hindered by the low quality of the samples. Here we report a synthesis of high-quality Janus MLs on gold substrates by thermal exchange reaction taking…

The exceptional electronic and photonic properties of the monolayers of transition metal dichalcogenides including the spin–orbit splitting of the valence and conduction bands at the K points of the Brillouin zone make them promising for novel applications in electronics, photonics and optoelectronics.…
One‐pot chemical vapor deposition (CVD) growth of large‐area Janus SeMoS monolayers is reported, with the asymmetric top (Se) and bottom (S) chalcogen atomic planes with respect to the central transition metal (Mo) atoms. The formation of these 2D semiconductor monolayers takes place upon the thermodynamic‐equilibrium‐driven…
A simple, large area, and cost‐effective soft lithographic method is presented for the patterned growth of high‐quality 2D transition metal dichalcogenides (TMDs). Initially, a liquid precursor (Na 2 MoO 4 in an aqueous solution) is patterned on the growth substrate using the micromolding in capillaries…
