Substrate surface effects on electron-irradiated graphene

چکیده
Chemical, mechanical, thermal and/or electronic properties of bulk or low-dimensional materials can be engineered by introducing structural defects to form novel functionalities. When using particles irradiation, these spatially arranged create complex structures, like sensing circuits, where the lateral resolution defective areas plays a fundamental role. Here, we show that patterned low-energy electrons in monolayer graphene sheets with strongly defined surface supporting substrate. Indeed, two-dimensional micro-Raman mapping revealed surroundings irradiated contain unintentional lattice, whose density depends on methods exploited clean surface. By combining Monte Carlo simulations analysis Raman modes, attributed modifications mainly action back-scattered and electrons-created secondaries. The latter reactive radicals at interface between affect areas. Hence, pattern produced high removing any organic contaminants from reducing thickness substrate, order minimize number secondary electrons.

Surface stress of graphene layers supported on soft substrate
We obtain the surface stress of a single layer and multilayers of graphene supported on silicone substrates by measuring the deformation of the graphene-covered substrates induced by the surface tension of liquid droplets together with the Neumann's triangle concept. We find that the surface stress of the graphene-covered substrate is significant larger than that of the bare substrate, and it i...

Graphene monolayers supported on oxide substrates have been demonstrated with superior charge mobility and thermal transport for potential device applications. Morphological corrugation can strongly influence the transport properties of the supported graphene. In this paper, we theoretically analyze the morphological stability of a graphene monolayer on an oxide substrate, subject to van der Wa...
متن کاملSynthesis of Graphene Based Membranes: Effect of Substrate Surface Properties on Monolayer Graphene Transfer
In this work, we report the transfer of graphene onto eight commercial microfiltration substrates having different pore sizes and surface characteristics. Monolayer graphene grown on copper by the chemical vapor deposition (CVD) process was transferred by the pressing method over the target substrates, followed by wet etching of copper to obtain monolayer graphene/polymer membranes. Scanning el...
