Abstract

In this paper, we review some of our ARPES results on the superconducting and pseudo gaps in Bi₂Sr₂CaCu₂O_8+x. We find that optimally and overdoped samples exhibit a d-wave gap, which closes at the same temperature, T_c, for all k points. In underdoped samples, a leading edge gap is found up to a temperature T* > T_c. We find that T* scales with the maximum low temperature gap, increasing as the doping is reduced. The momentum dependence of the pseudogap is similar to that of the superconducting gap; however, the pseudogap closes at different temperatures for different k points.
