Impact of oxygen plasma treatment on carrier transport and molecular adsorption in graphene

Abstract

Transport property variation in O2 plasma treated graphene and related enhancement in NH3 sensing.

Single-particle study: effects of mercury amalgamation on morphological and spectral changes in anisotropic gold nanorods

“…Energetic plasma treatment commonly removes organic capping material (e.g., CTAB bilayer) to improve surface modification in AuNPs. [10][11][12][13] We reported the morphological and spectral changes of single AuNRs for various plasma treatment times in our previous study. 14 Furthermore, we demonstrated that the silica coating in AuNRs@mSiO 2 enhances the AuNR core stability against oxygen plasma treatment.…”

The stability of graphene and boron nitride for III-nitride epitaxy and post-growth exfoliation

“…This O atoms create the D and D 0 peaks of graphene, which are similar to those of the O 2 plasma-treated graphene. 33,34 It is also accurately demonstrated that Al generated by Al 2 O 3 decomposition does not lead to graphene-loss because graphene is observed across the whole surface of all samples over 1200 C. From the Raman data alone, as shown in Fig. 1b, we can assume that the decomposed Al 2 O 3 substrate affects the D and D 0 peak of graphene, but it does not lead to grapheneloss.…”

Direct measurement of K+ ion efflux from neuronal cells using a graphene-based ion sensitive field effect transistor

“…6,17 Both the mobility and the carrier concentration are similar to those reported earlier. 8,10 GISFET characterization…”

“…This issue can be addressed by fabricating graphene-based ISFETs (GISFETs), which uses impervious graphene as the ion sensing layer, which is typically coated with an ion selective membrane (that prevents damage to the graphene layer itself). Due to its high carrier mobility and atomically thin nature, graphene has demonstrated excellent ionic sensitivity, [6][7][8][9] making it very well suited for ion efflux measurements.…”
