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…
Thickness-Induced Topological Phase Transition Investigated by Helicity Dependent Photocurrent in -Sn/CdTe(110)
Tengfei Liu, Xiyu Hong, Zhe Li +10
-Sn exhibits a rich topological phase diagram, yet experimental methods to tune and distinguish these phases remain limited. Here, we investigated the helicity-dependent photoc…
Universally optimizable strategy for magnetic gaps towards high-temperature quantum anomalous Hall states via magnetic-insulator/topological-insulator building-blocks
Zhe Li, Feng Xue, Xin-Yi Tang +4
Optimizing the magnetic Zeeman-splitting term, specifically the magnetic gap of the topological surface states (TSSs), is a crucial issue and central challenge in advancing higher-…
Designing Guidance for Multiple Valley-based Topological States Driven by Magnetic Substrates: Potential Applications at High Temperatures
Xiyu Hong, Zhe Li
Valley-based topological phases offer a wealth of exotic quantum states with tunable functionalities, driven by the valley degree of freedom. In this work, by constructing heterost…
