In fact, II-VI LHs can be regarded as inherently passivated 2D materials, with thin (<0.5 nm) inorganic layers passivated by chemically coordinated alkylamines of lengths up to 3.6 nm. However, to our knowledge, there has been no systematic study relating the stability of II-VI LHs with the identity of the surface-bound ligands. Furthermore, the mechanism of II-VI LH degradation is not fully understood.
