Caption: This image shows ARPES measurements of Calcium doped graphene. Left: the Fermi surface of graphene (top) and the Dirac cone (bottom). Right: The kink in the spectral function in the two crystallographic main directions. The scientists analyzed the strength of the kink in order to estimate the superconducting critical temperature.
