“…Therefore, the process temperature is additionally increased sometimes by substrate [125] or radiative heating. In contrast, low temperature (usually less than 100 o C) [126] and room temperature DLC deposition methods have also been previously attempted for flexible [127] and plastic [128] materials.…”

“…It has been reported that for DLC films, current densities up to 15 mA.cm −2 is stable for prolonged emission durations of up to an hour. 27 This indicates that no graphitization of the film has occurred, and that the temperature during field emission was below 600 • C. In our work, we tested the Fe400 samples up to current densities of only 2 mA.cm −2 , and can thus assume that the temperature during field emission testing did not reach the Curie temperature of γ-Fe 2 O 3 , which is given as 677 • C. 28…”

A γ-Fe 2 O 3 coated carbon nanotube (CNT) core-shell structure with dual magnetic and field emission properties was successfully fabricated by a simple one-step technique. The γ-Fe 2 O 3 shell is deposited on vertically aligned multi-walled CNTs by chemical vapor deposition using ferrocene as the precursor at process temperatures of 200, 400 and 600 • C. At 400 • C, the γ-Fe 2 O 3 shell formed a polycrystalline coating of polygonal nanoparticles on the CNTs. Enhanced field emission performance was observed with a threshold field of 4.7 Vμm −1 compared to pristine CNTs at 5.6 Vμm −1 . Magnetic measurements revealed that the γ-Fe 2 O 3 -CNT composites demonstrated ferrimagnetic behavior with high saturation magnetization of 52.3 emu/g and coercivity of 237 Oe at room temperature.Fabricating nanostructures that exhibit two or more different properties is highly desirable for simultaneous and efficient technological applications. This expansion of functionalities of a pre-existing material is also advantageous for scaling down of devices in the effort to maximize utilization and minimize cost. Such multi-functional nanostructures can be achieved by effectively combining two different kinds of materials into nanocomposites, thereby forming heterojunctions at the interface. There are several ways to fabricate multi-functional nanocomposites, one of which is through the configuration of a core-shell structure. In this configuration, the core material acts as the template and supplies the main properties of the resulting composite. The shell material imparts additional functionalities and can also enhance the properties of the core. For example, t-ZnO/SnO 2 core-shell nanostructures showed new luminescence properties induced by epitaxial interfaces, 1 and Fe 3 O 4 /TiO 2 core-shell nanotubes were reported to exhibit dual magnetic and electromagnetic wave absorption characteristics. 2 In the field of biotechnology, magnetic-fluorescent nanocomposites such as Co/CdSe, Fe 3 O 4 /CdTe and CoFe 2 O 4 /silica have been extensively studied for use in multimodal imaging applications. [3][4][5] Because it is possible to enhance or alter the properties of carbon nanotubes (CNTs) by modifying their surface, CNTs are promising building blocks for multi-functional nanocomposites. CNTs have, for example, been reported to exhibit enhanced optical absorption in the UV-visible region when encased in a CdS shell, 6 and have been used as imaging agents with near-infrared absorption and magnetic capabilities when combined with Fe 3 O 4 . 7 In addition, their unique morphology and remarkable properties such as high aspect ratio, structural integrity, and high chemical stability 8 make CNTs an ideal candidate for electron emitters in vacuum nanoelectronic devices. Field emission performance of CNTs has been widely reported to have improved through coating with wide bandgap materials such as MoO, SiO 2 and MgO, due to the formation of Schottky barriers. 9,10 If a suitable material for the coating is selected, additional functionalities can be ...

“…Generally, LIGNs possess prominent, vertically aligned sharp-edged graphene materials (cf. Figure 2a), resulting in a high aspect ratio [17,18,26,27,28,29,30,31,32,33,34,35,36,37] and therefore excellent FEE performance. The J e versus time curve, measured at an applied field of 0.75 V/μm (Figure 4b), showed that the FEE current density was very stable for a period of 160 min.…”

This paper presents a plasma display device (PDD) based on laser-induced graphene nanoribbons (LIGNs), which were directly fabricated on polyimide sheets. Superior field electron emission (FEE) characteristics, viz. a low turn-on field of 0.44 V/μm and a large field enhancement factor of 4578, were achieved for the LIGNs. Utilizing LIGNs as a cathode in a PDD showed excellent plasma illumination characteristics with a prolonged plasma lifetime stability. Moreover, the LIGN cathodes were directly laser-patternable. Such superior plasma illumination performance of LIGN-based PDDs has the potential to make a significant impact on display technology.
