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…
Thickness Estimation of Epitaxial Graphene on SiC using Attenuation of Substrate Raman Intensity
Shriram Shivaraman, M. V. S. Chandrashekhar, John J. Boeckl +1
A simple, non-invasive method using Raman spectroscopy for the estimation of the thickness of graphene layers grown epitaxially on silicon carbide (SiC) is presented, enabling simu…
Ultrafast Optical-Pump Terahertz-Probe Spectroscopy of the Carrier Relaxation and Recombination Dynamics in Epitaxial Graphene
Paul A. George, Jared Strait, Jahan Dawlaty +4
The ultrafast relaxation and recombination dynamics of photogenerated electrons and holes in epitaxial graphene are studied using optical-pump Terahertz-probe spectroscopy. The con…
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…
