我们利用短脉冲层间隧穿光谱在60 ns的时间尺度上的Bi 2Sr 2CaCu 2 O 8 + δ系统。结果表明，当注入电流密度接近60 kA/cm（2），注入功率面密度接近90 kW/cm（2）时，自加热的影响可以忽略不计。利用这种技术，我们可以精确地观察到超导能隙、赝能隙和起伏结构，而几乎不受自加热的影响。(C)2003年，美国物理学会。
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.
