Electric field exfoliation and high-T-C superconductivity in field-effect hole-doped hydrogenated diamond (111)

Thibault Daniel Pierre Sohier

We investigate the possible occurrence of field-effect induced superconductivity in the hydrogenated (111) diamond surface by first-principles calculations. By computing the band alignment between bulk diamond and the hydrogenated surface, we show that the ...

Supramolecular architectures of molecularly thin yet robust free-standing layers

Henning Paul-Julius Stahlberg, Mina Moradi, Patrick Shahgaldian

Stable, single-nanometer thin, and free-standing two-dimensional layers with controlled molecular architectures are desired for several applications ranging from (opto-)electronic devices to nanoparticle and single-biomolecule characterization. It is, howe ...

Characterizing the maximum number of layers in chemically exfoliated graphene

László Forró, Bálint Náfrádi, Péter Szirmai, Ferenc Simon, Julian Ayrton Englert, Bence Gábor Márkus

An efficient route to synthesize macroscopic amounts of graphene is highly desired and bulk characterization of such samples, in terms of the number of layers, is equally important. We present a Raman spectroscopy-based method to determine the typical uppe ...

Self-sensing, tunable monolayer MoS2 nanoelectromechanical resonators

Andras Kis, Dumitru Dumcenco, Guilherme Migliato Marega, Sajedeh Manzeli

Excellent mechanical properties and the presence of piezoresistivity make single layers of transition metal dichalcogenides (TMDCs) viable candidates for integration in nanoelectromechanical systems (NEMS). We report on the realization of electromechanical ...

Equipartition of Energy Defines the Size-Thickness Relationship in Liquid-Exfoliated Nanosheets

Nicola Marzari, Davide Campi

Liquid phase exfoliation is a commonly used method to produce 2D nanosheets from a range of layered crystals. However, such nanosheets display broad size and thickness distributions and correlations between area and thickness, issues that limit nanosheet a ...

Metal-Sulfide Catalysts Derived from Lignosulfonate and their Efficient Use in Hydrogenolysis

Paul Joseph Dyson, Xile Hu, Zhaofu Fei, Antoine Philippe Van Muyden, Xiang Li, Lichen Bai, Xinjiang Cui, Sijie Liu

Catalytic lignosulfonate valorization is hampered by the in situ liberation of sulfur that ultimately poisons the catalyst. To overcome this limitation, metal sulfide catalysts were developed that are able to cleave the C-O bonds of lignosulfonate and are ...
