Spectroscopic evidence for a pseudogap in the normal state of underdoped high-critical temperature superconductors.

Summary

The authors present a study of underdoped BSCCO (bismuth 2212) using angle-resolved photoemission spectroscopy, which directly measures the momentum-resolved electron excitation spectrum of the copper-oxygen planes. They found that a pseudogap with d-wave symmetry opens up in the normal state below a temperature higher than critical temperature, and develops into the d-wave superconducting gap once phase coherence is established below critical temperature.
