Model calculations of plasma excitations for arrays of cylindrical nanotubes

Abstract:

In this thesis we attempt to do calculations of the collective plasma excitations for an electron gas confined to the surface of cylindrical nanotubules in various spatial configurations. We present a self-consistent formalism of the dispersion relation for the plasmons and for the particle-hole modes as functions of the wave vector qz along the axis of the nanotube(s). These results have been obtained in the random phase approximation (RPA) for nanotubules of arbitrary radii, Ri.

In our formalism, a magnetic field is at times directed along the axis of the nanotube and its spectra analyzed. We propose a general method for calculating the oscillator strength of the plasma excitations; determined the contribution of the plasmon and particle-hole excitations to the absorption coefficient, and investigated and tried to explain the Rashba effect within the context of cylindrical geometry on the nanotubules.

About ProQuest Dissertations & Theses
With over 2.3 million records, the ProQuest Dissertations & Theses (PQDT) database is the most comprehensive collection of dissertations and theses in the world. It is the database of record for graduate research.

The database includes citations of graduate works ranging from the first U.S. dissertation, accepted in 1861, to those accepted as recently as last semester. Of the 2.3 million graduate works included in the database, ProQuest offers more than 1.9 million in full text formats. Of those, over 860,000 are available in PDF format. More than 60,000 dissertations and theses are added to the database each year.
