Relative positions of valence (left upward columns) and conduction bands (right downward columns) in 2D heterostructures for Δε < 2%, −0.22 eV < ΔE < 0.1 eV, Eg > 0.3 eV. The five bilayers considered in detail in this work are highlighted with thicker outline, and the calculated BCS gaps Δ for heterostructures 1, 2, and 3 are shown.
