Magnetic properties of molecular beam epitaxy-grown ultrathin Cr2Ge2Te6 films down to monolayer limit on Si substrates
Pengfei Ji, Ruixuan Liu, Tianchen Zhu +13
Cr2Ge2Te6, a prototypical van der Waals ferromagnetic semiconductor, have attracted significant interest for its potential applications in high-performance spintronics. However, th…
Dimensional crossover and topological nature of the thin films of a three-dimensional topological insulator by band gap engineering
Zhenyu Wang, Tong Zhou, Tian Jiang +10
Identification and control of topological phases in topological thin films offer great opportunity for fundamental research and the fabrication of topology-based devices. Here, com…
Superconductivity in Few-Layer Stanene
Menghan Liao, Yunyi Zang, Zhaoyong Guan +11
A single atomic slice of α-tin-stanene-has been predicted to host quantum spin Hall effect at room temperature, offering an ideal platform to study low-dimensional and topological…
Realizing an Epitaxial Stanene with an Insulating Bandgap
Yunyi Zang, Tian Jiang, Yan Gong +12
Stanene, a single atomic layer of Sn in a honeycomb lattice, is predicted a candidate wide bandgap two-dimensional (2D) topological insulator and can host intriguing topological st…
Dimensional Crossover Induced Topological Hall Effect in a Magnetic Topological Insulator
Chang Liu, Yunyi Zang, Wei Ruan +5
We report transport studies of Mn-doped Bi2Te3 topological insulator (TI) films with accurately controlled thickness grown by molecular beam epitaxy. We find that films thicker tha…
Interference Evidence for Rashba-Type Spin-Split on Semimetallic WTe2 Surface
Qing Li, Jiaqiang Yan, Biao Yang +11
Semimetallic tungsten ditelluride (WTe2) displays an extremely large non-saturating magnetoresistance (XMR), which is the subject of intense interest. This phenomenon is thought to…
Experimental observation of Dirac-like surface states and topological phase transition in PbSnTe(111) films
Chenhui Yan, Junwei Liu, Yunyi Zang +12
The surface of a topological crystalline insulator (TCI) carries an even number of Dirac cones protected by crystalline symmetry. We epitaxially grew high quality PbSnT…
