Nanoparticle Solutions for Printed Electronics
Abstract
This project had a technological focus on the development of silicon nanoparticle based electronic devices. The level of uniformity and control of the essential electronic, structural, mechanical, and thermal properties was only possible with a thorough understanding of the nanomaterial properties, the complex microstructure of the printed composite, and the physical processes governing charge, and energy transport. Significant progress was made towards all 4 long-term study goals of the project: the internal and surface structure of the nanoparticles and their influence on charge transport; agglomeration and clustering of nanoparticles; the microstructure of the printed composite and multiscale modeling of the transport of charge and energy; and the prediction of the properties and the input of this knowledge into the design of electronic devices. This project was highly collaborative with a significant investment in human capacity development. It was therefore integrated into and complemented projects funded the USAID Higher Education Development US-Africa Initiative, the UCT Vice Chancellors s Strategic Initiative and the commercial development by UCT s spin-out company PST Sensors. These were complemented by temperature dependent electrical characterization, providing input to charge transport, which led to the development of the first new type of transistor functionality in 65 years.
