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

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

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 ...

Suppressing Nucleation in Metal–Organic Chemical Vapor Deposition of MoS2

Andras Kis, Davide Deiana, Dmitry Ovchinnikov, Dmitrii Unuchek, Hokwon Kim

Toward the large-area deposition of MoS2 layers, we employ metal–organic precursors of Mo and S for a facile and reproducible van der Waals epitaxy on c-plane sapphire. Exposing c-sapphire substrates to alkali metal halide salts such as KI or NaCl together ...

Doping characteristics of iodine on as-grown chemical vapor deposited graphene on Pt

Olivier Renault, Nicolas Chevalier, Hokwon Kim

Using laboratory X-ray photoelectron emission microscopy (XPEEM), we investigated the doping efficiency and thermal stability of iodine on as-grown graphene on Pt. After iodine adsorption of graphene in saturated vapor of I-2, monolayer and bilayer graphen ...
