By using large single crystals of YBa2Cu3Or, precise temperature and doping dependence of the c-axis infrared active phonons are investigated. The effect of the superconducting gap opening on the phonon self-energy is observed for the optimally doped crystal but not for the overdoped crystal, which
It is well known that nonequilibrium populations of phonons can be generated in bulk semiconductors by the relaxation of photoexcited hot electrons. In this paper we demonstrate that nonequilibrium phonons can also be generated in quantum wells by picosecond lasers and then probed by time-resolved R
