Review of two microwave applications of carbon nanotubes: nano-antennas and nano-switches

A High-Luminescence Fringelike Field Emission from Screen-Printed Carbon Nanotube and Zinc Oxide Composite Film

“…The main reasons are contributed to remove of carbonaceous particles, such as fullerenes, nanoparticles and amorphous phases at high sintering. The high crystallinity is beneficial for field emission [4,18]. Figures 3(a,b) show the lighting images of pure CNT and CNT-ZnO film cathode.…”

“…Since the discovery of carbon nanotubes (CNTs) [1], the application of CNTs as field emitters has been widely investigated for the possible development of electronic and photonic nanodevices, such as field emission displays, X-ray sources and microwave devices [2][3][4]. Chemical vapor deposition (CVD) and screen-printing are two widely used methods for CNT film fabrication [5][6][7][8].…”

Nanotechnologies for Improving Food Quality, Safety, and Security

“…In addition to printed systems, some research groups are exploring the use of carbon nanotubes as antenna [77,78] . However, this technology is not as highly developed as conductive inks based on metal nanoparticles.…”

Carbon Nanotubes in Passive RF Applications

“…Other RF and microwave applications like switches, filters and resonators can also be obtained by using electromechanical propertied of carbon nanotubes. (Demoustier et al 2008) introduced an RF nanoswitch based on vertically aligned carbon nanotubes. It consists of carbon nanotube perpendicular to the substrate.…”
