论文摘要
Cuprate超导体BI2SR2CACU2O8+δ（BSCCO）一直是晶体结构内的固有的Josephson交界处，是连贯，连续和紧凑的THZ光源的有前途的候选者。在本文中，我们利用BSCCO跨旋风连接器使用晶状体晶体来生产THZ发射器装置，与单晶相比，可以轻松获得。结果，我们成功地观察到了跨晶球固有的约瑟夫森交界处的发射，频率约为0.7 THz。我们的发现可能会扩大BSCCO超导体对THZ发射源的适用性。
Cuprate superconductor Bi2Sr2CaCu2O8+δ (BSCCO) has been a promising candidate of a coherent, continuous, and compact THz light source owing to its intrinsic Josephson junction inside the crystal structure. In this paper, we utilized BSCCO cross-whisker junctions to produce THz emitter device using the whisker crystals which can be easily obtained compared with single crystals. As a result, we have successfully observed the emission from the cross-whisker intrinsic Josephson junction, with frequency of ~0.7 THz. Our findings might enlarge the applicability of BSCCO superconductors for the THz emission source.
