/ Abstract
at bands located just below the chemical potential. We observe a superconducting gap of 20 meV, which indicates that this system is in the strong coupling regime. The emergence of a coherent peak below the critical temperature T c and diminished spectral weight at the chemical potential above T c closely resembles the spectral characteristics of the cuprates.
