Description

Plasmonic nanostructures will be interfaced with carbon nanotubes in order to measure electrical transport while simultaneously monitoring structural and chemical changes through plasmon-enhanced Raman scattering. By using plasmonic structures interfaced to nanotubes, we will remove the limitations of resonant Raman spectroscopy and will be able to study fundamental aspects of e.g. current limitation in nanotubes without complications related to changes in resonance conditions, as well as providing fundamental information concerning the nanotube/nanoantenna interface. The team consists of four groups with complementary expertise in all key aspects of the project. The devices to
be developed in the course of the collaboration will serve as a test bed for interfaces between single molecules and nanoantennas that are promising for fundamental studies in molecular electronics as well as for single-molecule detection.

Key findings

Use of fountain nanopen lithography to controllably write aligned carbon nanotubes on a substrate.
Determination of ways to manipulate CNT and AU nanoparticles to enhance plasmonic enhanced Raman spectra.
Fabrication of CNT photonic crystals and first demonstration of electromechanically tunable CNT PC in visible range.
