From: Degradation behaviors and mechanisms of MoS2 crystals relevant to bioabsorbable electronics

a OM and AFM images of the monolayer MoS2 crystals with low-angle (1°) and high-angle (60°) GBs after accelerated degradation in PBS solution at 75 °C for 3 weeks. b, c Schematics of the degradation behaviors and mechanisms of monolayer MoS2 crystals with four types of dislocations and defects, including LAGBs, HAGBs, single-point defects, and multiple-point defects
