Fig. 2. The HfS2/MoTe2 bilayer heterostructure. Yellow ball and light blue ball represent sulfur and hafnium, respectively. Orange and dark blue balls represent tellurium and molybdenum, respectively. (a) Top view: [1, 0, 0] represents zigzag direction, [0, 1, 0] represents armchair direction. (b) Side view: d representation layer distance. (c) Band structure and DOS of HfS2/MoTe2 bilayer heterostructure. The illustration is a Brillouin region with a high symmetry label.
