Abstract

The great appeal of van-der-Waals materials is the possibility to fabricate artificial multilayer structures, consisting of different materials, with arbitrary but well controlled relative crystal orientations. We investigate WSe2-MoSe2 heterobilayers with different twist angles q ± d between the two layers, by low-frequency Raman scattering. In sufficiently aligned samples with q = 0°, or q = ...
