It is shown that the quality of contact made to the specimen can lead to wildly erroneous values of Jc' Pulsed current techniques give more reliable Jc values, but the results can still be distorted by the presence of thermoelectric effects. Methods of making contact to these materials are evaluated

Recently it has been shown that high resolution photoemission spectroscopy can be used to measure the energy gap of the high T c superconductors. The purpose of this paper is to review the results obtained by this technique and to compare the values of 2 &fKT c with those measured by tunneling or in
