Femtosecond mid-infrared study of YBa2Cu3O7-delta
Femtosecond near-infrared excitation of optimally-doped and underdoped YBa2Cu3O7-delta leads to an ultrafast fill-in of the much-discussed (ab)-plane mid-infrared conductivity gap. Transients taken fi om the underdoped material reveal two gap constituents with distinctly different recovery dynamics...

| 要約: | Femtosecond near-infrared excitation of optimally-doped and underdoped YBa2Cu3O7-delta leads to an ultrafast fill-in of the much-discussed (ab)-plane mid-infrared conductivity gap. Transients taken fi om the underdoped material reveal two gap constituents with distinctly different recovery dynamics and saturation behaviour. |
