(color online) The top view (top panels) and side view (bottom panels) of atomic structures of (a) TaX₂ monolayer, (b) TaX monolayer, and (c) TaX/Al₂O₃. The blue, brown, purple, and red spheres represent Ta, X (S, Se, or Te), Al, and O atoms, respectively. d₁, d₂, and d₃ denote the Ta–X, X–O, and Ta–Al bond lengths, respectively. Δh indicates the buckling distance of the TaX monolayer. (d) Density of states (DOS) of the Al₂O₃(0001) surface. The Fermi energy is set to be the zero point of energy.
