Welcome to the ASIN Group Homepage




20-11-14 Prof. Duesberg's News and Views article titled "Heterojunctions in 2D semiconductors: A perfect match" has been published in Nature Materials. This article discusses recent reports on the growth of 2D heteromaterials and outlines the promise these materials hold for commercial applications. The paper also features artwork by ASIN group member Christian Wirtz.

04-11-14 Congratulations to Dr. Hye-Young Kim who has been awarded funding under the Science Foundation Ireland (SFI) Advance Award Programme. Details of this programme can be found here.



31-10-14 Chanyoung Yim's paper "Investigation of the optical properties of MoS2 thin films using spectroscopic ellipsometry" has been listed as one of the most highly cited papers in Applied Physics Letters published in 2014 and has been made free to download for a limited time.



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.

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.
