Intrinsic Defects, Fluctuations of the Local Shape, and the Photo-Oxidation of Black Phosphorus

Shows that intrinsic structural defects in black phosphorus act as sites for photo-oxidation by dramatically lowering the energy barrier for oxygen bonding — from over 10 eV in pristine material down to 1.6–6.8 eV at defect sites — making the material vulnerable to degradation under ordinary visible and UV light. The local geometry of defects is characterised using discrete differential geometry.
