Complex Index of Refraction of Multi-walled Carbon Nanotubes in Strong Terahertz Fields

Creator:

McCuen, Dalton R.

Abstract:

Carbon nanotubes are the subject of intense interest in virtually every field, from medicine to nano-scale electrical components. Multi-walled nanotubes exhibit a strong nonlinear response to high-field strength terahertz radiation. This research uses terahertz pulses with field strength exceeding 1 MV/cm generated by means of optical rectification utilizing a lithium...

Bandgap measurements of nonspecular materials using a bifurcated fiber optic method of diffuse reflectance

Creator:

Wells, Blake

Abstract:

A method for determining bandgap energy using diffuse reflection is presented. The method uses bifurcated fiber optic cables to measure the diffuse reflection of diffusely reflective materials. The absorption spectrum is extrapolated from the diffuse reflection spectrum and used to determine the bandgap of powdered materials. The theory of nonspecular...
