Friction Anisotropy–Driven Domain Imaging on …

Graphene produced by exfoliation has not been able to provide an ideal graphene with performance comparable to that predicted by theory, and structural and/or electronic defects have been proposed as one cause of reduced performance. We report the observation of domains on exfoliated monolayer graphene that differ by their friction characteristics, as measured by friction force microscopy.

Monolayer Graphene Transfer onto Hydrophilic …

Monolayer graphene, however, is almost totally impermeable even to helium atoms [8,9], and the key factor for its use as a separation membrane, especially for water purification applications, is to transfer and support the CVD-grown monolayer graphene to the targeted substrates [10,11,12]. Graphene utilization in a wide range of applications is ...

Pushing the conductance and transparency limit of ...

Monolayer graphene coated with 20 mM HTB shows a high transparency of 98.3% at λ = 550 nm, 1.3% increase in absolute value compared to the pristine monolayer graphene used (97%). The optical images provide direct evidence of the substantial increase in transparency caused by the HTB coating (SI Appendix, Fig. S5B). This favorable effect of HTB ...

Graphene adhesion on MoS2 monolayer: An ab initio …

The geometric and electronic structures of graphene adsorption on MoS 2 monolayer have been studied by using density functional theory. It is found that graphene is bound to MoS 2 with an interlayer spacing of 3.32 Å and with a binding energy of −23 meV per C atom irrespective of adsorption arrangement, indicating a weak interaction between graphene and MoS 2.

Wafer-Scale Growth of Single-Crystal Monolayer …

Several methods have been reported for the growth of monolayer graphene into areas large enough for integration into silicon electronics. However, the electronic properties of the graphene are often degraded by grain boundaries and wrinkles. Lee et al. (p. [286][1], published online 3 April) showed that flat, single crystals of monolayer graphene can be grown by chemical-vapor deposition on ...
