Abstract 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.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
