Diameter-Selective Raman Scattering from Vibrational Modes in Carbon Nanotubes
- A. M. Rao, E. Richter, M. Dresselhaus
- Chemistry, PhysicsScience
- 10 January 1997
Single wall carbon nanotubes (SWNTs) that are found as close-packed arrays in crystalline ropes have been studied by using Raman scattering techniques with laser excitation wavelengths in the range…
Structural and vibrational properties of fullerenes and nanotubes in a nonorthogonal tight‐binding scheme
- M. Menon, E. Richter, K. Subbaswamy
- Chemistry, Physics
- 15 April 1996
A simple, computationally efficient method for the evaluation of structural and vibrational properties of carbon is presented. The scheme is based on the generalized tight‐binding molecular dynamics…

Kinetic Model of Stage Transformation and Intercalation in Graphite
- P. Hawrylak, K. Subbaswamy
- Materials Science
- 26 November 1984
We derive a set of diffusion equations based on time-dependent Landau-Ginzburg theory, which is capable of describing the role of domains in stage transformations and intercalation in layered…
Complex scalar fields in one dimension with fourfold phase anisotropy: Solitary-wave solutions
- K. Subbaswamy, S. E. Trullinger
- Physics
- 1 March 1979
We present solitary-wave solutions to a set of coupled nonlinear wave equations resulting from a model Lagrangian for a complex scalar (two-component) field in one space and one time dimension in the…
Raman scattering from potassium iodide near the melting point
- J. Giergiel, P. Eklund, K. Subbaswamy

Bond alternation, on-site Coulomb correlations, and solitons in polyacetylene
- K. Subbaswamy, M. Grabowski
- Chemistry
- 15 August 1981
We explore the effect of including electronic on-site Coulomb correlations on the energy of solitons in polyacetylene within an unrestricted Hartree-Fock calculation for finite chains. For parameters…
Structural and vibrational properties of Si clathrates in a generalized tight-binding molecular-dynamics scheme
- M. Menon, E. Richter, K. Subbaswamy
- Chemistry
- 1 November 1997
The structural and vibrational properties of Si in two fourfold coordinated crystalline structures (clathrates) are studied and compared with those in the diamond structure using a generalized…
