Ultrafast Relaxation Dynamics of Hot Optical Phonons in Graphene
Haining Wang, Jared H. Strait, Paul A. George +8
Using ultrafast optical pump-probe spectroscopy, we study the relaxation dynamics of hot optical phonons in few-layer and multi-layer graphene films grown by epitaxy on silicon car…

Measurements of the Carrier Dynamics and Terahertz Response of Oriented Germanium Nanowires using Optical-Pump Terahertz-Probe Spectroscopy
Jared H. Strait, Paul A. George, Mark Levendorf +3
We have measured the terahertz response of oriented germanium nanowires using ultrafast optical-pump terahertz-probe spectroscopy. We present results on the time, frequency, and po…
