Prof Georg Duesberg graduated in Physical Chemistry from the University of Kassel, Germany. He worked at the Max-Planck-Institute Stuttgart and Trinity College Dublin from 1997–2001 on a collaborative European project, were he dealt with purifying, assembling and imaging carbon nanotubes. He was the first person to characterise individual carbon nanotubes by Raman spectroscopy. He received his PhD from the University of Tuebingen, Germany in 2000. From 2001–2005 he worked at the Infineon AG, Corporate Research Department, Munich, Germany. Here his research was focused on the integration of bottom-up structures grown into CMOS based devices. Wafer scale CVD as well as the growth of individual nanotubes from lithographically defined nano-holes are among his achievements. From 2005–2007 Prof Duesberg worked in the Thin Films Department of the Qimonda AG, Dresden, Germany on the implementation of new carbon nanostructured films into future DRAM technology. In July 2007 he moved to Dublin to take on a position as a Principal Investigator in CRANN and Associate Professor in the School of Chemistry, Trinity College Dublin. He is a recognised world leader in the area of the integration of carbon nanotubes into CMOS technology.

Project title CSET: : Integrated Nanoscale Devices
Summary The grand mission for Theme 2 in CSET is to develop innovative science for the delivery of new sub 10 nm device technologies into industry. In order to achieve this goal we have developed a series of inter-related collaborative strands that reflect the grand challenges of ICT. This centres on how nanodevice structures and in particular small arrays of around ten of these might be positioned on a substrate and contacts made for their individual e-characterisation. The aim here is to develop self-organised multi-level structures (consisting of active device layers, interconnects, gates and circuitry) that might function as logic circuitry and which address requirement of bottom-up technologies in terms of device feature size, scalability and density.

Project title Nano EI
Summary The objective of this project would be to demonstrate interconnect technologies at the 11nm node. It will focus on the metallisation challenges and be composed of two main themes; 1. The first theme will look at scaling of the existing Cu technology which will require innovations for seed layers, barrier layers, conformal Cu deposition and capping. The target dimensions will be for 20 nm trenches and 15nm vias with 2:1 aspect ratios at the ‘11nm node’, with initial work starting at the 22nm node with 40nm trenches and 30nm vias. Parameters to be considered will include resistivity, contact resistances, electromigration performance and mechanical stress. 2. The second theme will look at alternative 1d technologies such as CNT synthesis for via and trench. It will be shown that these new materials/methods offer viable alternatives to meeting the demanding challenges at this level of scaling. Demonstrator arrays will be produced so that the performance of the materials can be assessed by the industrial partner in a ‘real’ environment and the performance of the methods in the two themes can be compared against state-of-the-art structures in Cu. The project will consider scale-up, ongoing from demonstrator single layers through to multiple layer connected structures. Although patterning will not be a focus topic of this work, some considerable patterning and integration work will need to be performed so that structures with the required dimensions can be made available.

Project title CRANN-HP collaborative research project on development of flexible, transparent conducting films and devices from nano-materials
Summary This proposed research programme builds on a successful existing three year collaboration where the partnership of CRANN with Hewlett-Packard (HP) has resulted in the development of flexible, transparent and conductive thin films of both carbon nanotube mats and polymer / carbon nanotube composites which now represent the international the state-of-the-art1.
