Black phosphorene (BP) is not stable at ambient conditions, so atomic defects and oxidation effects are unavoidable in BP samples in the experiment. The effects of these defects on the performance of the BP nanoresonators are still unclear. Here, we perform classical molecular dynamics to investigate the effects of the vacancy and oxidation on single-layer BP nanoresonators at different temperatures. We find that the vacancy causes a strong reduction in the quality factor of the nanoresonators, while the oxidation has a weaker effect on the nanoresonators. More specifically, a 2% concentration of randomly distributed single vacancies is able to reduce the quality factor by about 80% and 40% at 4.2 K and 50 K, respectively. We also find that the quality factor of the nanoresonators is not sensitive to the distribution pattern of the vacancy defects.
