Growth and characterisation of epitaxial graphene for electronic and sensing applications

The extraordinary properties of graphene, a single sheet of carbon atoms (e.g. monodimensional structure, high conductivity, low-noise characteristics) are expected to be exploited in the next generation of electronic devices and gas sensors. These applications require a perfect control of the growth of graphene layers, and an optimum integration with the processes and materials used in the semiconductor industry.This project aims at studying the growth of graphene obtained by heating crystalline SiC at high temperature in Ar atrmosphere and ultra …

Two dimensional heterostructures on SiC for new electronics

The present electronic technology is approaching the limit to the smallest circuit element achievable, and the future electronic devices will depend critically on the development of novel approaches. Two dimensional materials seem to offer an exciting perspective, and the advent of graphene (a single layer of carbon atoms in a honeycomb structure) sparked a huge interest, but its application to electronics are limited by the absence of a band gap.A new perspective has been open by other 2D materials which …

Low cost, long life metal-ion capacitors and supercapacitors for renewable energy storage

Australia boasts rich wind and solar energy resources. To avoid fluctuations placing severe burden on the power grids, a reliable and efficient battery storage is required.The present technology based on lithium-ion batteries suffers from high manufacturing cost, poor safety and short life-span.A new kind of storage devices, metal-ion capacitors (MICs), are expected to overcome the storage and the charging speed of the traditional batteries in the near future, opening new avenues for renewable energy resources. The basic structure of MICs …

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 …
