Tuning the Chemical and Mechanical Properties of Conductive MoS₂ Thin Films by Surface Modification with Aryl Diazonium Salts.

ABSTRACT: Molybdenum disulfide (MoS₂) is a promising material for applications in sensors, energy storage, energy conversion devices, solar cells, and fuel cells. Because many of those applications require conductive materials, we recently developed a method for preparing a conductive form of MoS₂ (c-MoS₂) using dilute aqueous hydrogen peroxide in a simple and safe way. Here, we investigate modulating the chemical and mechanical surface properties of c-MoS₂ thin films using diazonium chemistry. In addition to a direct passivation strategy of c-MoS₂ with diazonium salts for electron-withdrawing groups, we also propose a novel in situ synthetic pathway for modification with electron-donating groups. The obtained results are examined by Rama
