MgB2 energy gap determination by scanning tunnelling spectroscopy

MgB2 energy gap determination by scanning tunnelling spectroscopy

We report scanning tunnelling spectroscopy (STS) measurements of the gap properties of both ceramic MgB2 and c-axis oriented epitaxial MgB2 thin films. Both show a temperature dependent zero bias conductance peak and evidence for two superconducting gaps. We report tunnelling spectroscopy of superco...
