Abstract

We report the results of phonon relaxation processes obtained from picosecond transient thermoreflectance measurements of single-crystal La2CuO4+y (y∼0.06). Nonequilibrium heating was found to occur on a picosecond time scale. The time scale of the nonequilibrium heating is a sensitive measurement of the modest electron-phonon interaction (λ≤0.1) in the nonsuperconducting La2CuO4+y. [ABSTRACT FROM AUTHOR]
