Hybrid Heterostructures from Transition Metal Dichalcogenides and Organic Systems

#nanomaterials #nanotechnology #AP/MTT

Atomically thin transition metal dichalcogenides (TMDs) present extraordinary physicochemical properties that may not be accessible in bulk semiconductors. Recently, 2D hybrid heteromaterials have emerged upon integrating TMDs with molecular systems, including organic molecules, polymers, and metal-organic frameworks, that can tailor the TMD properties. The hybrid approach may enable future optoelectronics and energy applications. I will first introduce the field of 2D materials and describe how TMDs and their heterostructured combinations can be used in devices to maximize their unique properties. This talk will discuss our approach for modulating optoelectronic properties of individual flakes and heterobilayers using organic layers. We show, for example, that the intralayer photoluminescence and interlayer emission may be selectively and controllably tailored by a set of organic molecules with distinct properties. Related electronic transport and surface characteristics will also be delineated. With a vast library of organic molecules, this approach may form the basis of future applications. This presentation will be concluded with several exemplary applications.
