Understanding the structure-property relationships in reduced graphene oxide hydrogels

Graphene consists of hybridised carbon atoms in a hexagonal two-dimensional (2D) lattice. This material has extraordinary mechanical, thermal and electrical properties. However, one problem in practical applications is the aggregation and restacking between neighbouring graphene layers.In contrast, a possible way to avoid this problem is by transforming 2D graphene sheets into graphene hydrogel (GH) consisting of a three dimensional (3D) porous structure. Recently, 3D GH has been widely investigated in energy storage and conversion, catalysis and sensors. Furthermore, its accessible …

New 2D heterostructures on silicon carbide for two dimensional electronics

Graphene has attracted a great deal of interest due to its remarkable electronic, optical and mechanical properties. However the absence of a bandgap limits its use in many applications.Future applications in nanoelectronics will depend critically on the development of novel approaches to introduce a bandgap while preserving carrier mobility. An example includes stacking graphene with other two-dimensional (2D) materials with complementary properties.This project will look at systematically refining the integration of different 2D materials with graphene grown epitaxially on silicon …
