Catalyst Proximity-Induced Functionalization of h-BN with Quat Derivatives

Magalí Alejandra Lingenfelder, Gabriele Tocci, Bart Willem Stel, Huanyao Cun

Inert single-layer boron nitride (h-BN) grown on a catalytic metal may be functionalized with quaternary ammonium compounds (quats) that are widely used as nonreactive electrolytes. We observe that the quat treatment, which facilitates the electrochemical ...

Wafer-scale MOCVD growth of monolayer MoS2 on sapphire and SiO2

Aleksandra Radenovic, Andras Kis, Thomas La Grange, Ke Liu, Michal Daniel Macha, Yanfei Zhao, Hokwon Kim, Huanyao Cun

High-quality and large-scale growth of monolayer molybdenum disulfide (MoS2) has caught intensive attention because of its potential in many applications due to unique electronic properties. Here, we report the wafer-scale growth of high-quality monolayer ...

An electron acceptor molecule in a nanomesh: F(4)TCNQ on h-BN/Rh(111)

Huanyao Cun, Silvan Dino Marcos Roth

The adsorption of molecules on surfaces affects the surface dipole and thus changes in the work function may be expected. The effect in change of work function is particularly strong if charge between substrate and adsorbate is involved. Here we report the ...

Fermi surface map of large-scale single-orientation graphene on SiO2

Huanyao Cun

Large scale tetraoctylammonium-assisted electrochemical transfer of graphene grown on single-crystalline Ir(1 1 1) films by chemical vapour deposition is reported. The transferred samples are characterized in air with optical microscopy, Raman spectroscopy ...
