06-10-14 Maria O'Brien's paper entitled "Plasma assisted synthesis of WS2 for gas sensing applications" has been published in Chemical Physics Letters. This paper details the production of WS2 thin films using a scalable low-temerature, plasma assisted process and their subsequent usage for the detection of ammonia.

 

 

26-09-14 Sinéad Winters, Maria O'Brien and Christian Wirtz all took part in the TCD heat of Thesis in Three. In this competition PhD students explain their thesis in only 3 minutes using just 3 slides. Christian claimed second prize and will now go on to represent CRANN in the finals in The Sugar Club on the 20th of October. Free tickets for the final can be obtained by registering here.

07-05-14 Dr. Toby Hallam's paper titled "Strain, Bubbles, Dirt and Folds: A Study of Graphene Polymer-Assisted Transfer" has been accepted for publication in Advanced Materials Interfaces. This follows Toby's recent prize-winning poster on the same topic at the International Winterschool on Electronic Properties of Novel Materials (IWEPNM) in Kirchberg. This paper investigates the effects of graphene transfer using various polymers and introduces nitrocellulose based polymers as an attractive alternative to commonly used PMMA.

Group Overview




Carbon nano-structures appear in many different forms such as fullerenes, nanotubes, graphene, which are confined to zero, one and two dimensions respectively. They are stable at ambient conditions and exhibit exciting physical and chemical properties such as ballistic charge transport, high mechanical strength and the highest thermal transport known to mankind. In our group we focus on fabricating novel devices and concepts to exploit these properties for applications in ICT, bio-chemistry and renewable energy. Novel ICT devices such transistors, sensors and interconnects shall be realized by the integration of carbon nano-structures with state-of-the-art silicon processing techniques available in CRANN. Furthermore, new concepts for energy harvesting and conversion such as in solar cells and fuel cells on the basis of nano-carbons are investigated.

 

The research group combines top-down structuring techniques with the in-situ synthesis of novel functional nano-structures. The creation of such hybrid structures is aimed at the fabrication of new adaptive devices based on the bottom up growth of nano-materials with unique functionality. Using the hybrid approach the precession and scaling capabilities of silicon structuring technology can be maintained. We utilise state-of the art lithographic structuring and self-assembly techniques to obtain mesoscopic preforms such as AAO to integrate functional nano-materials. In particular, we aim to implement not only graphitic nano-structures such as carbon nanotubes and graphene but also inorganic/metallic nanowires.
