THz-time-domain spectroscopy of doped semiconductor superlattices
Winnerl, S.; Dreyhaupt, A.; Dekorsy, A.; Helm, M.
The search for Bloch gain in doped semiconductor superlattices is still a field of considerable interest. Our approach is to obtain the dynamic conductivity of doped biased GaAs/AlGaAs superlattices by measuring the transmission in the terahertz frequency range. We present experimental results on the electric transport in a wide temperature range and preliminary results for the THz transmission through superlattice mesa elements.
