the invasive s-wave pairing potential from Nb is incompatible with the intrinsic Cooper pair condensate in MoTe2. This incompatibility leads to strong stochasticity in the switching current and an unusual anti-hysteretic behaviour in the currentvoltage loops. There is also an asymmetry in the edge oscillations where,imToken,。

在边缘振荡中存在不对称性,边缘态很容易与体态区分开来,美国普林斯顿大学的N. P. Ong及其研究团队取得一项新进展,经过不懈努力, we track the anomalous features to field-induced switching of the device gap function between s-wave symmetry and the unconventional symmetry intrinsic to MoTe2. We infer that the behaviour of the gap function along the edges is different from that in the bulk.

we do not know if we can force their pairing symmetries to be different. Here we show that。
此外, 据悉,科研人员还不清楚是否可以强制改变它们的配对对称性。
the edge states are readily distinguished from the bulk states. The situation where a topological semimetal becomes superconducting so that Cooper pairs occupy both the bulk and the edge states is not well understood. In particular,当磁场穿过零点时,具体来说,当拓扑半金属转变为超导状态时。
