Compared to the single material of graphene or AgNW, the hybrid has significantly reduced sheet resistance (Supplementary Fig. 2) with slightly lower optical transmittance and haziness (Fig. 1c).
Compared with GO, the graphene dextran (GO DEX) conjugate shows reduced sheet sizes, increased thickness and significantly improved stability in physiological solutions.
While these levels are suitable for depletion-mode operation, realizing enhancement-mode devices ultimately depends on the ability to significantly reduce sheet charge.
It seems that doping is very necessary to reduce sheet resistance.
Further doping with Au3+ ions has also been shown to reduce sheet resistance to 110 Ω/sq at a transmittance of 90% [109, 110].
The hybrid thereby circumvents electron scattering due to defects in the graphene sheet, and reduces the sheet resistance by a factor of two.
In many cases, attention has been focused on targeting fibril formation by reducing β-sheet extension and assembly.
The average number of missing values was 1.1 in patients documented with the standard data sheet, and 3.1 for patients documented with the reduced data sheet (where pupil size and reactivity were not documented).
Phosphorus-based groups and residual oxygenated functional groups may reduce graphene sheet restacking to form graphite.
