The structural stability and band evolution of B₂H₂ monolayer. (a) The atomic structure of B₂H₂ monolayer. The four crystalline directions are labeled. (b) The phonon dispersion of a ZNR-as under 24% uniaxial strain. (c) The ELF of a ZNR-as under 24% uniaxial strain. Panels (d)–(f) are energy bands projected to boron atomic orbitals of B₂H₂ monolayer (d) without strain, (e) 20% tensile strain along armchair direction, and (f) 20% tensile strain along zigzag direction.
