Dr. John Nesbitt

After completing his Masters in Physics, and a research project on surface plasmon polaritons, John joined the NanoMaterials group at Southampton University. Since joining the group John has been investigating phonon population dynamics in single-walled carbon nanotubes (SWCNTs) using resonance Raman spectroscopy (RRS) and time-resolved incoherent anti-Stokes Raman spectroscopy (TRIARS) techniques, with a view to improve our understanding of reduced carrier mobility in SWCNTs under high-bias. His work has included an interpretation of the TRIARS intensity dynamics of second-order one-phonon and two-phonon (overtone) Raman features by applying the theory of double resonance (DR) Raman scattering.

John specialises in Raman spectroscopy techniques including: RRS, TRIARS, and SERS. His scientific interests include: Raman spectroscopy, single molecule electronics, low-coherence interferometry and the commercialisation of research.
