3D Biofabricated high-perfoRmance dna-carbon nanotube dIgital electroniCKS (3D-BRICKS). (3D-BRICKS)

Single-walled carbon nanotubes (SWCNTs) possess unique optical and electronic properties that depend critically on their exact chiral structure. By filling the hollow cores of the SWCNTs, new functionalities can be obtained, originating from the peculiar interaction of the encapsulants and the host SWCNTs. In this project, we will focus on filling SWCNTs with electron donor and acceptor molecules, that can result in n- and p-type doping of the host SWCNTs. Through the dependence on the ionization potential or electron affinity of the encapsulated molecules, it is expected that the doping level can be finely tuned by choosing the specific molecules (or a combination of different molecules) to be encapsulated. The development of reliable methods for SWCNT doping combined with chiral sorting methodologies, can lead to a breakthrough advancement in SWCNT-related applications, such as SWCNT-based field-effect transistors. The doped SWCNTs will be investigated by means of a wide range of experimental techniques, in particular EPR spectroscopy, that can directly access the doping level of the SWCNTs in a quantitative manner, and optical spectroscopic techniques, such as absorption spectroscopy, wavelength-dependent resonant Raman spectroscopy and infrared fluorescence-excitation spectroscopy and imaging
