利用高分辨角分辨光电子能谱研究了电子掺杂高温超导体Nd_（2-x）Ce_xCuO_4中电子态的掺杂依赖性。我们观察到热斑周围的高能赝能隙
The doping dependence of electronic states in an electron-doped high-temperature superconductor (HTSC) Nd2-xCexCuO4 was studied by high-resolution angle-resolved photoemission spectroscopy. We observed that the high-energy pseudogap around the hot spot sh
