NIST only participates in the February and August reviews.
The future of nanoelectronic technologies requires new device concepts and novel materials. The electronic (band) structure and energy band levels are defining electronic properties that govern how an electronic device operates, and these properties are dependent on many factors such as heterointerfaces formed and its microstructure. In this opportunity, we will investigate the electronic properties of candidate quantum materials or organic (molecular) semiconductors. We will use and develop measurement approaches to determine key electronic properties such as electron-based spectroscopies, nanometer-scale imaging with energy filtering using a photoemission electron microscope (PEEM), and other optical measurements. Research is done in close collaboration with other groups at NIST with expertise in complementary measurement techniques, materials growth, and device fabrication.
