Quantum Transport in Large-Scale Patterned Nitrogen-Doped Graphene
It has recently been demonstrated how the nitrogen dopant concentration in graphene can be controlled spatially on the nano-meter scale using a molecular mask. This technique may be used to create ballistic electron optics-like structures of high/low doping regions; for example, to focus electron beams, harnessing the quantum wave nature of the electronic propagation. Here,… Read More

Chiral and conductive viologen-based supramolecular gels exhibiting tunable charge-transfer properties
Redox-active conductive supramolecular gels involving highly ordered chiral assemblies of small organic molecules are very promising soft materials for many applications ranging from catalysis to electronics. However, combining all these properties in the same material has so far remained a difficult task. We now report the synthesis and detailed structural, rheological, and electrical characterizations of… Read More

Positional and Rotational Molecular Degrees of Freedom at a Roughened Metal–Organic Interface: The Copper–Fullerene System and Its Multiple Structural Phases
The hybrid metal–organic interaction that molecular monolayers experience when deposited on metallic substrates can compete with intermolecular interactions and produce a variety of on-surface orders. The variety is already important when the molecule/substrate interface remains atomically flat. Here, we address the case of fullerene molecules deposited at room temperature on a Cu(111) surface with interface… Read More

Hybrid molecular graphene transistor as an operando and optoelectronic platform
Lack of reproducibility hampers molecular devices integration into large-scale circuits. Thus, incorporating operando characterization can facilitate the understanding of multiple features producing disparities in different devices. In this work, we report the realization of hybrid molecular graphene field effect transistors (m-GFETs) based on 11-(Ferrocenyl)undecanethiol (FcC11SH) micro self-assembled monolayers (μSAMs) and high-quality graphene (Gr) in a… Read More

Quasi-1D Polymer Semiconductor – Diarylethene Blends: High Performance Optically Switchable Transistors
Optically switchable field-effect transistors (OSFETs) are non-volatile photonic memory devices holding a great potential for applications in optical information storage and telecommunications. Solution processing of blends of photochromic molecules and π-conjugated polymers is a low-cost protocol to integrate simultaneously optical switching and charge transport functions in large-area devices. However, the limited reversibility of the isomerization… Read More
