单库珀对约瑟夫森晶体管是一种同时具有电荷量子化和相位相干性的器件。相干量子相移现象是约瑟夫森相干性的对偶，而电荷量子化是磁通量子化的对偶。给出了一种新型超导器件--单磁通晶体管的实验论证和理论描述。我们的输运测量显示了外加磁场对临界电压的周期性调制。所获得的电流-电压特性显示出滞后行为，我们将其归因于载流子的本征自热。(C)2013 AIP出版有限责任公司。
The single Cooper pair josephson transistor is a device that exhibits at the same time charge quantization and phase coherence. Coherent quantum phase slip phenomenon is "dual" the Josephson phase coherence, while the charge quantization is dual to the flux quantization. We present the experimental demonstration and the theoretical description of a new superconducting device-single flux transistor, which is dual to the single Cooper pair transistor. Our transport measurements show the periodic modulation of the critical voltage by the external magnetic field. The obtained current-voltage characteristics show the hysteretic behavior, which we attribute to the intrinsic self-heating of charge carriers. (C) 2013 AIP Publishing LLC.
