Synthesis of reduced graphene oxide (rGO) via chemical reduction
AIP Conference Proceedings, 2015Natural flake Graphite was used as the starting material for the graphene synthesis. In the first step flake graphite was treated with oxidizing agents under vigorous conditions to obtain graphite oxide. Layered graphite oxide decorated with oxygen has large inter-layer distance leading easy exfoliation into single sheets by ultrasonication giving ...

Enhanced thermoelectric properties of MoS2 with the incorporation of reduced graphene oxide (RGO)
Journal of Alloys and Compounds, 2020Abstract Molybdenum disulfide (MoS2), a transition metal dichalcogenides (TMDs) is a potential candidate for thermoelectric due to its inherent low thermal conductivity. However, its low electrical conductivity confines its practical usage. In this paper, we have synthesized nanocomposite of MoS2 with reduced graphene oxide (RGO) and demonstrated a ...

Infrared response of vanadium oxide (VOx)/SiNx/reduced graphene oxide (rGO) composite microbolometer
Microelectronics Reliability, 2018Abstract Much attention has been paid to the photoresponse of vanaduim oxide (VOx) and amorphous silicon based microbolometer for long-wavelength infrared detection under un-cooled operation condition in recent decades. However, the outstanding physical and chemical properties of graphene and reduced graphene oxide (rGO) stimulate their potential for
