180${}^{\circ }$-twisted bilayer ReSe${}_2$ as an artificial noncentrosymmetric semiconductor

S. Akatsuka, M. Sakano, T. Yamamoto +18

We have fabricated a 180${}^{\circ }$-twisted bilayer ReSe${}_2$ by stacking two centrosymmetric monolayer ReSe${}_2$ flakes in opposite directions, which is expected to lose spatial invers…
