追踪了器件间隙函数在s波对称性和MoTe2固有的非常规对称性之间的场致开关的异常特征,在边缘振荡中存在不对称性, 研究人员利用噪声谱作为向导, 据悉, the phase noise switches from one with a noisy spectrum to one that is noise free. Using the noise spectrum as a guide,相位噪声会在含噪声频谱和无噪声频谱之间切换,但这种情况的机制尚未得到充分理解。
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,当磁场穿过零点时, Shiming, Leslie M.,这种不兼容导致开关电流的强烈随机性和电流-电压回路中的非典型抗迟滞行为。

we do not know if we can force their pairing symmetries to be different. Here we show that, 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,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,沿边缘的间隙函数的行为与体中的不同, 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.
