Dr. Law’s research group focuses on creating new materials and new structures to control infrared and terahertz light. We work in the fields of plasmonics, metamaterials, and topological materials. Our materials can squeeze light into tiny volumes, make light bend backward, and slow light down. These devices have applications in thermal and biological imaging, infrared and terahertz detectors, chemical sensing, environmental monitoring, security and defense, and quantum computing.
The materials and and structures we create are grown using molecular beam epitaxy, a technique in which a material is grown one atomic layer at a time–3D printing at the nanoscale. With this technique, we can create extremely high quality materials and complicated structures. Molecular beam epitaxy is widely used in industry to create lasers and light emitting diodes, among other devices. After growth, the materials are characterized using the shared equipment in the Advanced Materials Characterization Lab, the Center for Advanced Microscopy and Microanalysis, and the University of Delaware Nanofabrication Facility.
Highly-motivated graduate or undergraduate students in Materials Science and Engineering, Physics, or Electrical Engineering who are interested in joining the group should contact Dr. Law at email@example.com.
