In this webinar, Phillip Keathley will start by reviewing the fundamental principles behind strong-field electron emission and how it enables sub-femtosecond electron emission. From there, Dr. Keathley will review recent efforts using these properties of strong-field electron emisison for the development of chip-scale petahertz electronics. In particular, Dr. Keathley will review his team's efforts using nanoplasmonics to enable the use of low-energy driving pulses (picojoule- to nanojoule-level) for applications such as shot-to-shot carrier-envelope-phase detection and optical field sampling with attosecond resolution. Dr. Keathley will conclude by discussing how these nanoscale devices are enabling new capabilities. These new capabilities include field-resolved optical detection as well as the ability to transfer information between devices over femtosecond timescales for petahertz-level memory and logic gates.

About the Presenter: Phillip D. Keathley from Massachusetts Institute of Technology

Dr. Keathley is a Principal Research Scientist in the Research Laboratory of Electronics (RLE) at MIT. His research spans the areas of ultrafast optics, strong-field science, attosecond physics, nanophotonics, nanoelectronics, and plasmonics. He is currently co-group leader of the Quantum Nanostructures and Nanofabrication group at MIT where he leads teams that develop optical-field-driven petahertz electronics, nanoscale free-electron light sources, and radiation-hard nanoscale vacuum-electronics. He received his B.Sc. and M.Sc. degrees in Electrical Engineering from University of Kentucky in 2009 where he was named an Astronaut Scholar. He received his PhD in Electrical Engineering and Computer Science from MIT in 2015 where he studied as a National Defense Science and Engineering Graduate Fellow (NDSEG). In 2018 he was named an Air Force Office of Scientific Research Young Investigator for investigating methods for petahertz processing of fields using nanoscale electron emitters.
