Noise Properties of Graphene-Polymer Thick-Film Resistors

Abstract

Graphene is a very promising material for potential applications in many fields. Since manufacturing technologies of graphene are still at the developing stage, low-frequency noise measurements as a tool for evaluating their quality is proposed. In this work, noise properties of polymer thick-film resistors with graphene nano-platelets as a functional phase are reported. The measurements were carried out in room temperature. 1/f noise caused by resistance fluctuations has been found to be the main component in the specimens. The parameter values describing noise intensity of the polymer thick-film specimens have been calculated and compared with the values obtained for other thick-film resistors and layers used in microelectronics. The studied polymer thick-film specimens exhibit rather poor noise properties, especially for the layers with a low content of the functional phase.

Electrical properties of graphite-glass thick-film resistors

“…during an electrical discharge or an electron emission. So far, various carbon-based composites were reported to work as transparent conductors (Watcharotone et al, 2007), resistive layers (Dziedzic, 1997(Dziedzic, , 2005Rao, 2007;Mleczko et al, 2017) or as an active part in sensors for detection of chromium (Hallam et al, 2010), proteins (G omez-Mingot et al, 2011) or heavy metals (Aragay, Pons and Merkoi, 2011). However, in the literature, it is not clearly defined what are the electrical properties of the graphite and graphene layers/ paths.…”

Metrology and Measurement Systems

“…Drift rates of the order of 10 −9 (Ω/Ω)/year and stabilities of about 5 • 10 −8 Ω/Ω) have been reported [9,10]. Graphene is also used as a material for standard resistors, and its noise properties are investigated [11].…”
