These setups allow the simultaneous use of humidity, temperature, electrical biases, and illumination as independently controlled stress factors. The setups and various experiments executed are presented. Engineering Resonance Raman Spectroscopy of Extreme Nanowires and Other 1D Systems David C. Smith1, Joseph H. Spencer1, Jeremy Sloan2, Liam P. McDonnell1, Harrison Trewhitt2, Reza J. Kashtiban2, Eric Faulques3 1School of Physics and Astronomy, University of Southampton, 2Department of Physics, University of Warwick, 3Institut des Matériaux Jean Rouxel, University of Nantes CNRS The paper describes a method for producing extreme nanowires by melt infiltration into carbon nanotubes and how 1D systems may be characterized and investigated using Resonance Raman Spectroscopy to determine vibrational and optical excitation energies.
