Strong Confinment of optical fields using localised surface phonon polaritons in cubic Boron Nitride
Ioannis Chatzakis, Athith Krishna, James Culbertson +4
Phonon polaritons (PhPs) are long-lived electromagnetic modes that originate from the coupling of infrared photons with the bound ionic lattice of a polar crystal. Cubic-Boron nitr…
Temperature Dependence of Wavelength Selectable Zero-Phonon Emission from Single Defects in Hexagonal Boron Nitride
Nicholas R. Jungwirth, Brian Calderon, Yanxin Ji +3
We investigate the distribution and temperature-dependent optical properties of sharp, zero-phonon emission from defect-based single photon sources in multilayer hexagonal boron ni…
Very Slow Cooling Dynamics of Photoexcited Carriers in Graphene Observed by Optical-Pump Terahertz-Probe Spectroscopy
Jared H. Strait, Haining Wang, Shriram Shivaraman +3
Using optical-pump terahertz-probe spectroscopy, we study the relaxation dynamics of photoexcited carriers in graphene at different temperatures. We find that at lower temperatures…
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…
Carrier Recombination and Generation Rates for Intravalley and Intervalley Phonon Scattering in Graphene
Farhan Rana, Paul A. George, Jared H. Strait +4
Electron-hole generation and recombination rates for intravalley and intervalley phonon scattering in Graphene are presented. The transverse and the longitudinal optical phonon mod…
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…
