“…In the case of CNF growth on silicon substrates using a C 2 H 2 / NH 3 mixture it was determined that Si x N y deposits with x and y around 0.5. 18,89 Thus there is a delicate balance to the gas ratios used in regard the desired surface condition; for CNFs without an amorphous carbon coating a C 2 H 2 :NH 3 ratio of 20% or below must be used; 68 however for ratios lower than this, sidewall deposition of Si x N y material becomes more favorable.…”

Carbon nanofibers are high-aspect ratio graphitic materials that have been investigated for numerous applications due to their unique physical properties such as high strength, low density, metallic conductivity, tunable morphology, chemical and environmental stabilities, as well as compatibility with organochemical modification. Surface studies are extremely important for nanomaterials because not only is the surface structurally and chemically quite different from the bulk, but its properties tend to dominate at the nanoscale due to the drastically increased surface-to-volume ratio. This review surveys recent developments in surface analysis techniques used to characterize the surface structure and chemistry of carbon nanofibers and related carbon materials. These techniques include scanning probe microscopy, infrared and electron spectroscopies, electron microscopy, ion spectrometry, temperature-programed desorption, and atom probe analysis. In addition, this article evaluates the methods used to modify the surface of carbon nanofibers in order to enhance their functionality to perform across an exceedingly diverse application space.

“…Carbon nanotubes (CNTs) are one of the most noteworthy materials for electronic, mechanical, and optical devices due to their unique structural and quantum characteristics [1][2][3][4][5][6][7][8][9]. Such carbon nanomaterials need to be functionalized on their surface in order to interact with other substances.…”

“…111 The possible application of VANTAs and VACNFs as microelectronic interconnects has driven many studies to characterize their end-contact quality. 71,[111][112][113][114][115] The reported end-contact resistances vary significantly from one measurement to another suggesting a wide spectrum of influencing parameters. Important parameters are the surface roughness of the metal underlayer as well as its surface oxidation, 115 the wettability of the metal underlayer and its work function, 112 and the growth conditions.…”

This paper gives an assessment of vertically aligned carbon based varactors and validates their potential for future applications. The varactors discussed here are nanoelectromechanical devices which are based on either vertically aligned carbon nanofibers or vertically aligned carbon nanotube arrays. A generic analytical model for parallel plate nanoelectromechanical varactors based on previous works is developed and is used to formulate a universal expression for their voltage-capacitance relation. Specific expressions for the nanofiber based and the nanotube based varactors are then derived separately from the generic model. This paper also provides a detailed review on the fabrication of carbon based varactors and pays special attention to the challenges in realizing such devices. Finally, the performance of the carbon based varactor is assessed in accordance with four criteria: the static capacitance, the tuning ratio, the quality factor, and the operating voltage. Although the reported performance is still far inferior to other varactor technologies, our prognosis which stems from the analytical model shows a promise of a high quality factor as well as a potential for high power handling for carbon based varactors.
