Abstract

We have studied the photoexcited carrier dynamics in the electron-doped La2-xCexCuO4La2-xCexCuO4 (LCCO). In general, there is a slowing down of the relaxation as the temperature decreases. However, the quasiparticle lifetime is found to exhibit a quasi-divergence as the temperature approaches Tc from below. We have also observed picosecond rise time in the electron-doped LCCO, which is attributed to the Cooper pair breaking dynamics. The experimental results are analyzed by Rothwarf–Taylor model.
