Engineering interactions between 2D transition metal dichalcogenides and solid surfaces

We will explore methods of interface engineering to control the interaction strength in heterostructures of two-dimensional transition metal dichalcogenides (TMDCs) with solid surfaces and quantify this interaction using a range of spectroscopy and microscopy methods. We propose three distinct routes of interface manipulation: alloying of ultrathin metallic layers, hot-atom deposition, and pressure control. Through these routes, we intend to alter the interaction dynamics between monolayer TMDCs and solid substrates, in order to achieve control over the exfoliation yield, optoelectric properties, and chemical state of the TMDCs. We will then investigate the fundamental processes occurring at the TMDC/substrate interfaces, which underpin role of these systems in three key areas: (electro)wetting, energy conversion, and energy storage. Through the combination of innovative interface engineering and selected case studies of the interfacial processes, this research seeks to pave the way for the development of high-performance devices with enhanced functionality and efficiency.
