摘要: Low-field electron emission is obtained from the pinaster-like MoO$_{2}$ nanoarrays. The turn-on field of the pinaster-like MoO$_{2}$ nanoarrays is found to be as low as 2.39\,V/$\mu $m with the current density of 10\,$\mu $A/cm$^{2}$. The enhancement factor is extracted to be 3590 from the Fowler--Nordheim plot. These excellent emission properties are attributed to the special structure of the pinaster-like MoO$_{2}$ nanoarrays and confirmed by the calculation in the frame of the two -stage model. Our results show that the pinaster-like MoO$_{2}$ nanoarrays are promising candidate in realizing field emission displays.
