Large-scale synthesis and exciton dynamics of monolayer MoS₂ on differently doped GaN substrates.

ABSTRACT: Mixed dimensional van der Waals heterostructure based on layered two-dimensional molybdenum disulfide (MoS₂) interfaced to gallium nitride (GaN) has attracted tremendous attention due to its unique properties and application in novel electronic, optoelectronic, and quantum devices. However, developing facile synthesis methods and insights into the exciton dynamics for this system still remains a major challenge. Here, a simple and cost-effective method is demonstrated for large-scale synthesis of monolayer MoS₂ on differently doped GaN substrates. A mixed aqueous solution of Na₂MoO₄ and NaOH is spin-coated on GaN and sulfurated in one step by chemical vapor deposition (CVD). High quality monolayer MoS₂ nanosheets with side length over
