Projects and Programs

Designing the Nanoworld: Nanostructure, Nanodevices, and Nano-optics

Ongoing

Developing and exploiting nanodevices for quantum and nanotechnologies requires nanoscale and atomic scale modeling of ultrasmall structures, devices, their operation, and their response to probes. Key challenges of understanding physics at the quantum/classical interface and measurement at the

Nanoplasmonics and Three-Dimensional Plasmonic Metamaterials

Ongoing

Plasmonic materials are composed of metals and insulators that are ordered in geometric arrangements with dimensions that are fractions of the wavelength of light. Research groups are experimenting with a variety of geometric approaches, but all aim to exploit surface plasmons, which are light

Nanoscale Spectroscopy for Advanced Electronics, Quantum Materials and Devices

Ongoing

Semiconductor technologies are critical to U.S. economic and national security as they are essential to modern life in communications, healthcare, energy, etc. and also underpin many emerging technologies like quantum, artificial intelligence, high power electronics and advanced wireless (6G+). The

Single-molecule biosensors

Ongoing

We are developing new tools to investigate the energy landscape of single-molecule sensors. Our goal is to apply a wide-ranging array of technologies to probe the critical physicochemical properties of nanopore biosensors. These properties include the free energy of confinement for polymers as they
