Dr. Davis will describe his recent studies of the High-TC Superconductor BiSrCaCuO, using a high resolution very low temperature STM, in which single impurity atoms were used to probe the structure of the superconducting order parameter and the correlation between electrons.
Quasiparticle scattering at impurities generates localized impurity states at the atmoic scale.
The destruction of superconductivity within 1.5 nm of the Zn sites is observed. Audio for this talk requires sound hardware, and RealPlayer or RealAudio by RealNetworks. Begin continuous audio for the whole talk .
