Autor: Li, Zhun, Mi, Xinrun, Wang, Xinming, Lyu, Jian, Su, Na, Wang, Aifeng, Chai, Yisheng, Yuan, Bao, Luo, Wanju, Cheng, Hui, Gao, Jianxiang, Wang, Hongliang, Hao, Lijie, He, Mingquan, Shen, Junying, Sun, Young, Tong, Xin

In a magnetic skyrmion phase, magnetic moments form vortex-like topological textures which are of both fundamental and industrial interests. In $\beta$-Mn-type Co-Zn-Mn alloys, chrial magnetic skyrmions emerge above room temperature, providing a uniq

Gate-tuned ambipolar superconductivity with strong pairing interaction in intrinsic gapped monolayer 1T'-MoTe2

Autor: Tang, Fangdong, Wang, Peipei, Gan, Yuan, lyu, Jian, Wang, Qixing, Mi, Xinrun, He, Mingquan, Zhang, Liyuan, Smet, Jurgen H.

Gate tunable two-dimensional (2D) superconductors offer significant advantages when studying superconducting phase transitions. Here, we address superconductivity in exfoliated 1T'-MoTe2 monolayers with an intrinsic band gap of ~7.3 meV using electro

In this work, ~100 nm wide quantum anomalous Hall insulator (QAHI) nanoribbons are etched from a two-dimensional QAHI film. One part of the nanoribbon is covered with superconducting Nb, while the other part is connected to an Au lead via two-dimensi
