Instrumentation for Functionalized Two-Dimensional Nanoelectronic Heterostructures
Abstract
Funding is provided for the acquisition of instrumentation for functionalized two-dimensional nanoelectronic heterostructures, which is the subject of PI s current ONR-funded project. Two-dimensional (2D) nanomaterials (e.g., graphene, boron nitride, transition metal dichalcogenides, and black phosphorus) have emerged as leading candidates for next-generation electronic and optoelectronic technologies. By sequentially layering these 2D nanomaterials into van der Waals heterostructures, additional functionality and novel device structures can be achieved. Furthermore, the atomically thin nature of these nanomaterials implies that nearly all of their constituent atoms are on the surface, which implies that any adsorbates or neighboring materials can influence their properties. This DURIP proposal seeks to exploit this sensitivity to surface and interfacial chemistry by developing and studying chemical functionalization layers on 2D nanomaterials and their heterostructures. A comprehensive program is proposed ranging from molecularly precise ultra-high vacuum processing to device fabrication and testing based on scalable solution-based methodologies. In this manner, fundamental studies that aim to elucidate the physical mechanisms that underlie the electronic and optical properties of 2D nanomaterials can be efficiently translated to the design and optimization of 2D nanoelectronic heterostructure devices. Specifically, this DURIP proposal is seeking instrumentation that will enhance both the characterization and fabrication of functionalized 2D nanoelectronic heterostructures including: (1) Variable temperature scanning probe microscopy that will allow for molecular-scale imaging in ultra-high vacuum; (2) Aerosol jet printing to facilitate the fabrication of solution-processed 2D nanomaterial heterostructures; (3) Integrated glovebox and atomic layer deposition system for the encapsulation of 2D nanomaterial devices without ambient exposure; (4) Cryogenic probe station to enable variable-temperature charge transport measurements. Overall, this interrelated suite of instrumentation will substantially advance our ability to probe and exploit 2D nanoelectronic heterostructures, thus improving research productivity and maximizing the impact of our ongoing ONR-supported work.
