Abstract
In this response, we explain the points mentioned by R. Rani and R. Bhatia in their Comment for our previous paper [AIP Advances 5, 097130 (2015)], that the high value of β obtained in Song et al. [AIP Advances 5, 097130 (2015)] is misleading because it does not corroborate with the obtained Jmax, and the obtained value of Jmax is “low” in the mentioned study as compared to the reported values [J. Appl. Phys. 111, 044307 (2012) & Appl. Phys. Lett. 102, 033102 (2013)]. For the high value of β, the obtained current Jmax is corroborated but such high value is mainly due to the multistage effect when CNTs are deposited on the rough surface of reduced graphene. For the “low” Jmax, although this is true when compared with Sameera et al. [J. Appl. Phys. 111, 044307 (2012) and Appl. Phys. Lett. 102, 033102 (2013)], but we believe that our value is a generally common value when compared with other reports [Diam. Relat. Mater. 47, 1 (2014); J. Alloys Compd. 610, 659 (2014); J. Nanomater. 2013, 5239 (2013)] using the similar method as described in our paper. Therefore, the conclusions from the experimental results on field emission performance of CNT/graphene composite materials in our paper are reliable.
Highlights
Bhatia entitled “Comment on ‘Water-processed CNT/graphene hybrids with enhanced field emission properties’” claims that the high value of β obtained in Ref. 1 is misleading because it does not corroborate with the obtained Jmax, and the obtained value of Jmax is quite low in the mentioned study as compared to the reported values (Refs. 2 & 3)
It is attributed to the special structure of graphene so that the field enhancement factors of CNT/graphene composite materials can be greatly improved
It is well known that when the field emission performance is tested, the voltage applied between the anode and cathode electrodes needs to be adjusted to record the corresponding current
