Polarization-driven band topology evolution in twisted MoTe${}_2$ and WSe${}_2$

Xiao-Wei Zhang, Chong Wang, Xiaoyu Liu +3

Motivated by recent experimental observations of opposite Chern numbers in $R$-type twisted MoTe${}_2$ and WSe${}_2$ homobilayers, we perform large-scale density-functional-theory (DFT…
