Title |
Femtosecond optical detection of quasiparticle dynamics in high-Tc YBa2Cu3O7- 8 superconducting thin films |
Date |
1990-11 |
Description |
Femtosecond dynamics of photogenerated quasiparticles in YBa2Cu307-δ superconducting thin films shows at T ≤ Tc two main electronic processes: (i) quasiparticle avalanche production during hot-carrier thermalization, which takes about 300 fsec; (ii) recombination of quasiparticles to form Cooper pairs which is completed within 5 psec. In contrast, nonsuperconducting epitaxial films such as PrBa2Cu3O7 and YBa2Cu3O6 show regular picosecond electronic response. |
