Abstract :
We report time-resolved carrier dynamics in Hg-Ba-Ca-Cu-O high-temperature superconductors using optical excitation and THz probe femtosecond spectroscopy. Picosecond quasiparticle dynamics observed in our experiments suggests that Hg-based materials are attractive candidates for high-speed photodetectors.
