Project description
Thin films of unconventional semiconductors could help boost electronics and solar technologies
Semiconducting single-walled carbon nanotubes (s-SWCNTs) are unique materials with promising potential for next-generation optoelectronics owing to their stability, conductivity and ability to transport energy in one direction. With the support of the Marie Skłodowska-Curie Actions programme, the DEF-TUBES project aims to create thin films and devices using aligned s-SWCNTs to explore how energy flows directionally and how it can be converted into electricity. The research will focus on isolating s-SWCNTs, incorporating them into photovoltaic devices and using advanced spectroscopic techniques to examine energy flow and charge generation. Project work will deepen understanding of one-dimensional energy flow in semiconducting materials, paving the way for more efficient optoelectronics.
Objective
Semiconducting Single-Walled Carbon Nanotubes (s-SWCNTs) are a unique class of semiconductor.s-SWCNTs hold significant promise for improving next generation optoelectronics because of their chirality dependent band, stability, conductivity and solution-processability.
More importantly, unlike the most common bulk semiconductors, s-SWCNT are intrinsically 1D. That means that, films made of aligned tubes can transport energy along a specified direction, allowing potentially to control energy and exciton flow in previously unprecedented ways. However, even if films of aligned s-SWCNT have been experimentally demonstrated, directional charge flow has not yet been measured nor has the absorbed light energy been converted into electricity.
The main aim of this project is to fabricate thin-film and devices of aligned SWCNT to investigate directional energy flow and its conversion into electrical current, by leveraging ultrafast spectroscopies.
This work is driven by three primary goals:1) isolating s-SWCNTs, depositing thin-films and incorporating them into photovoltaic devices; 2) exploiting two-dimensional electronic and photocurrent spectroscopy to examine the energy flow channels and kinetics, and 3) to explore ultrafast free-charge generation with sub-15 fs time resolution to understand how to enhance device performance.
This research methodology involves the development of innovative s-SWCNT device architectures, consisting of layered films with controlled bandgap gradients and aligned tubes, in order to optimize exciton and energy directionality and efficiency. Cutting-edge spectroscopic techniques will enable comprehensive mapping of the of energy and exciton dynamics.
Thought the integration of expertise from the hosting institutions; this project will contribute significantly to the understanding and employment of 1D energy flow in semiconducting materials, facilitating the development of more effective electronics and optoelectronics.
