Abstract
Negative differential conductivity (NDC) is an essential feature for amplification and generation of electromagnetic waves. Particularly, NDC in the terahertz (THz) range has been attracting much attention for realizing compact solid-state THz sources for various kinds of applications. In this presentation, we will propose novel method of determining complex conductivity spectra, sigma(omega), by using time-domain THz spectroscopy.
