摘要：

The energy range for the short-pulse interlayer tunneling spectroscopy for Bi2Sr2CaCu2O2+delta has been extended from less than 100 meV per single junction to greater than 200 meV by adopting composite current pulses. This improvement eliminates the breakage of specimens during the measurements almost completely, leading to the observation of a likely doping-dependent dip-and-hump structure in the tunneling spectrum of Bi2Sr2CaCu2O8+delta.
