Light-matter interactions in Semiconductor Nanostructures

Ongoing
We investigate the interaction of light with semiconductor-based nanostructures. We extend concepts of entanglement and coherence in atomic physics to our solid-state systems. Our devices are based on semiconductors, like GaAs. We use InAs quantum dots (QDs) in GaAs as artificial atoms; they have

Measuring Topological Insulator Surface State Properties

Ongoing
A family of TI materials can by synthesized by combining binary compounds of Bismuth (Bi) or Antimony (Sb) with Selenium (Se) and Tellurium (Te) to form Bi 2Se 3, Bi 2Te 3, and Sb 2Te 3 compounds. In these material compounds the spin of the electron has a strong interaction with the motion of the

Photonic Dosimetry

Ongoing
With this effort, NIST is responding to industry needs for traceable, measurement solutions that can resolve spatial variations of absorbed dose at the level of individual components on a silicon wafer or bacteria on surgical instruments. Presently, there is only limited traceability to national

For over three decades, scanning probe microscopy (SPM) has been a key method for exploring material structures and functionalities at nanometer and often

Nagaoka ferromagnetism in 3 × 3 arrays and beyond

Author(s)
Yan Li, Keyi Liu, Garnett Bryant
Nagaoka ferromagnetism (NF) is a long-predicted example of itinerant ferromagnetism (IF) in the Hubbard model that has been studied theoretically for many years
