The consistent behavior of negative Poisson's ratio with interlayer interactions

Abstract

Negative Poisson’s ratio (NPR) is of great interest due to the novel applications in lots of fields. Films are the most commonly used form in practical applications, which involves multiple...

Alloying enhanced negative Poisson's ratio in two-dimensional aluminum gallium nitride (AlxGa1−xN)

“…This is consistent with graphene and BN monolayers. 45 Moreover, a sudden drop appears at larger tensile strains in the lattice constant, as well as in the corresponding pressure [Fig. 2(e)] and energy change per atom [Fig.…”

Penta-OsP2 and penta-Rhs2 sheets derived from marcasite and pyrite with low lattice thermal conductivity

“…58 It is worth noting that the electronic properties of a system with a NPR would change significantly under external stress due to the variation of the orbital interactions of atoms induced by the changes in the bond lengths and bond angles, as demonstrated in multilayer graphene. 59 More discussions on the mechanical properties of the two structures are presented in Text S2 and Fig. S3 in the ESI †…”

Band Structure and Quantum Transport of Bent Bilayer Graphene

“…H (H ≈ 3.4 nm hereafter) is the interlayer distance between the OBR and OTR, and h (h ≈ 2.48 nm hereafter) is the interlayer distance between the IBR and ITR. The interlayer distances in bent bilayer graphene are 0.46 nm [ 36 ]. The system can be described by two topological equivalent geometries suffering effective electric and magnetic fields, as shown in Figure 1 c–e.…”
