Moreover, we find that the screen effect also highly depends on the length of nanowires on the field emission performance. The turn-on fields increase from 6.6 to 13.6 V μm−1, and β values LOXO-101 mouse decrease from 1,857 to 699 after the 10-h growth. The screen effect is predominated after the length of nanowires increases, namely the longer growth time, thereby degrading the field emission performance. Consequently, the turn-on fields and β values change from 13.6 V μm−1 and 699 to 6.6 V μm−1 and 1,857, respectively, as the growth time of Sn-doped ITO NWs decreases into 3 h. The detailed screen effect in terms of electrical potential and NW density was investigated

in details. The findings provide an effective way

of improving the field emission properties for nano-emitter application. Acknowledgment This work was supported by the National Science Council, Taiwan, under grant number NSC-99-2221-E-007-069-MY3.
