Low-dimensional electronic materials, including nanowires and atomically-thin 2D layered compounds, have attracted considerable attention for potential application in nanoscale devices, including Beyond-CMOS electronics, chemical sensors, batteries, LEDs, photodetectors, etc. Prospective advantages over traditional thin-film devices include exceptional structural quality, high surface-to-volume ratio, bottom-up device engineering and on-chip integration on variety of substrates, and utilization of quantum size effects. In this project, we are developing metrology needed for the synthesis, processing, and characterization of semiconducting low-dimensional materials to enable reliable nanoscale device development and manufacturing. We operate several CVD reactors for scalable fabrication of ultra-thin epi-layers of MoS2 and other transition metal dichalcogenides, as well as vertical nanowire arrays of silicon and Group III nitrides. These fabrication tools are complemented by post-growth device assembly, nanoscale structural/electrical/optical measurements, and comprehensive multiscale & multiphysics material and device modeling under Material Genome Initiative. We are open to extending these approaches to new classes of electronic materials with reduced dimensionality, such as delta-doped diamond and ultra-thin metal nitride films, as guided by emerging nanotechnology needs.
We are interested in research topics related to the fabrication and scalable assembly of low-dimensional structures with controlled properties into functional devices and to the development of methods for correlating their structural, compositional, electrical, and optical properties to enable a broad range of electronic, photonic, and sensor applications, including for flexible/transparent electronics, Beyond-CMOS logic and memory, etc. Excellent collaborative opportunities exist with staff in other NIST laboratories.
