WebIt was demonstrated that low-valence dopants (Zn 2+ and Cu 2+) enhance the adhesion strength of interface I, while high-valence dopants (Mo 6+ and Sb 5+) play the opposite role. Secondly, the strengthening effects of low-valence dopants were further verified in four candidate interfacial models with different atomic structures (denoted as II–V).
