摘要：

We utilize the short pulse interlayer tunneling spectroscopy on a 60 ns time scale for the Bi2Sr2CaCu2O8+delta system. The results indicate that the influence of self-heating is negligible up to an injection current density of similar to60 kA/cm(2) and an injection power areal density of similar to90 kW/cm(2). By means of this technique, we are able to observe the superconducting gap, the pseudogap, and the dip-and-hump structure precisely with little influence from the self-heating.
