Measurements of the THz absorption and dispersion of ZnTe and their relevance to the electro-optic detection of THz radiation
(AIP Publishing, 1999-06-07)
Via THz time-domain spectroscopy, we have measured the absorption and index of refraction of single-crystal (110) ZnTe from 0.3 to 4.5 THz. We find that the absorption is dominated by two lower-frequency phonon lines at ...
Nature of conduction in doped silicon
(American Physical Society, 1997-02-10)
Via ultrafast optoelectronic THz techniques, we are able to test alternative theories of conduction by precisely measuring the complex conductivity of doped silicon from low frequencies to frequencies higher than the plasma ...
Observation of a Cole-Davidson type complex conductivity in the limit of very low carrier densities in doped silicon
(AIP Publishing, 1998-05-04)
Using THz time-domain spectroscopy to measure the complex conductivity of doped silicon from low frequencies to frequencies higher than the THz plasma frequency and the carrier damping rate, we were able to show in the ...
