Switching Chern number by sliding and gating in alternately twisted tetralayer MoTe2
Xiao-Wei Zhang, Kaijie Yang, Xiaodong Xu +2
Switching the bulk Chern number in topological materials is of central importance for the design of topological electronic devices. Motivated by recent observations of integer and…

Twist-angle transferable continuum model and second flat Chern band in twisted MoTe2 and WSe2
Xiao-Wei Zhang, Kaijie Yang, Chong Wang +3
We develop a twist-angle transferable continuum model for twisted transition metal dichalcogenide (tTMD) homobilayers, using tMoTe2 and tWSe2 as examples. All model parameters are…
