Carrier Lifetimes in a III-V-N Intermediate Band Semiconductor
J. N. Heyman, A. M. Schwartzberg, K. M. Yu +5
We have used transient absorption spectroscopy to measure carrier lifetimes in the multiband band semiconductor GaPAsN. These measurements probe the electron populations in the con…

Ultrafast THz Faraday Rotation in Graphene
J. N. Heyman, R. F. Foo Kune, B. A. Alebachew +2
Terahertz (THz) Faraday rotation measurements were performed to investigate carrier dynamics in p-type CVD graphene. We used static and time-resolved polarization-sensitive THz tra…

Carrier Heating and Negative Photoconductivity in Graphene
J. N. Heyman, J. D. Stein, Z. S. Kaminski +3
We investigated negative photoconductivity in graphene using ultrafast terahertz techniques. Infrared transmission was used to determine the Fermi energy, carrier density and mobil…
