Nanoimprint assisted transfer of different density vertically aligned ZnO nanorod arrays

Abstract

Nanoimprint assisted transfer method was used to make vertically aligned ZnO nanorod electronic devices. The method relies on the hot nanoimprint process performed in the transfer process, which enables ZnO nanorod arrays to easily penetrate into the PMMA transfer layers.

Transfer Printing of Solution‐Processed 3D ZnO Nanostructures with Ultra‐High Yield for Flexible Metasurface Color Filter

“…Thus, from Figure 5f–h, those pallets present the highest contrast and saturated color. In previously reported similar works, [ 48–50 ] the transferred nanorods are not vertically aligned and full of defects. Also, the reported transfer results lack transfer accuracy, which essentially modifies the lattice of original pattern, thus negating the designed functionality of the devices for some applications.…”

Close proximity electrostatic effect from small clusters of emitters

“…Thus, an investigation of how CPEE changes with the aspect ratio and the number of emitters in small clusters is necessary once the CPEE is observed when emitters in a LAFE form clusters. This kind of configuration is possible when nonuniform dense field emitter arrays are produced [10,11,17,27]. It is worth mentioning that the performance of the field emitters is affected by space charge due to the exponential dependence of the emitted current on the local electric field [26].…”

Modulating the size of ZnO nanorods on SiO2 substrates by incorporating reduced graphene oxide into the seed layer solution

“…1 On the other hand, Pihon et al added surfactant into synthesizing procedures to grow ZnO low-aspect ratio. 2 However, incorporating graphene, 3 which is a promising material because of its high thermal conductivity, electrical conductivity and strong mechanical strength, into the ZnO nanostructure growth processes has not been reported yet. Since employing graphene can enhance electric conductivity, 4 photovoltaic properties, 5 and anti-bacterial capability, 6 various nanodevices have been demonstrated with the ZnO NRs decorating graphene, with development industry, incorporating graphene has become an inexpensive and effective way to boost material properties and device performance.…”

“…9 In 2015 and 2016, Pruna et al have add graphene related materials into ZnO seed layer to grow ZnO nanorod array with outstanding characteristics. 10,11 In this research, we tried to incorporate reduced graphene oxide into ZnO seed layer solution to modulate the aspect ratio of the ZnO NRs on SiO 2 …”
