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…

Emission of Terahertz Radiation from SiC

Jared H. Strait, Paul A. George, Jahan Dawlaty +4

We report the emission of strong coherent broadband terahertz radiation from 6H-Silicon-Carbide (SiC) excited with optical pulses. The measured terahertz spectral signal-to-noise r…

Measurement of the Optical Absorption Spectra of Epitaxial Graphene from Terahertz to Visible

Jahan M. Dawlaty, Shriram Shivaraman, Jared Strait +6

We present experimental results on the optical absorption spectra of epitaxial graphene from the visible to the terahertz (THz) frequency range. In the THz range, the absorption is…
