Terahertz studies of carrier dynamics and dielectric response of n-type, freestanding epitaxial GaN
(AIP Publishing, 2003-04-28)
We report the characterization of the complex conductivity and dielectric function of GaN by terahertz time-domain spectroscopy. Transmission measurements are performed on an n-type, 180-um-thick, freestanding GaN crystal. ...
Quasioptic dielectric tetrahertz cavity: Coupled through optical tunneling
(AIP Publishing, 2001-04-23)
We report the observation of the well defined oscillation of a picosecond tetrahertz (ps THz) pulse within a dielectric concentric cy1indrica1 cavity, which is coupled to an incoming focused beam of ps THz pulses by the ...
THz Sommerfeld wave propagation on a single metal wire
(AIP Publishing, 2005-04-12)
We report an experimental and theoretical study of THz Sommerfeld wave propagation on a single copper wire. THz pulses are optoelectronically generated and launched onto 0.52-mm-diam copper wire, and the guided THz pulses ...
