Raman spectra of unfilled and filled carbon nanotubes: Theory
S. Gayen, S. N. Behera, S. M. Bose
The Raman spectra of two G-bands and a radial breathing mode (RBM) of unfilled and filled single-wall semiconducting and metallic carbon nanotubes have been investigated theoretica…
Model of the Interplay of Band J-T Effect with Magnetic Order Mediated by Exchange Interaction
G. Gangadhar Reddy, A. Ramakanth, S. K. Ghatak +3
A model calculation is presented with the aim to study the interplay between magnetic and structural transitions. The model consists of an orbitally doubly degenerate conduction ba…
Electronic properties of ordered and disordered linear clusters of atoms and molecules
S N Behera, S Gayen, G V Ravi Prasad +1
The electronic properties of one-dimensional clusters of N atoms or molecules have been studied. The model used is similar to the Kronig-Penney model with the potential offered by…
Theory of the tangential G-band feature in the Raman spectra of metallic carbon nanotubes
S. M. Bose, S. Gayen, S. N. Behera
The tangential G-band in the Raman spectra of a metallic single-wall carbon nanotube shows two peaks: a higher frequency component having the Lorentzian shape and a lower-frequency…
Interplay of spin density wave and superconductivity with different pairing symmetry
Haranath Ghosh, S. Sil, S. N. Behera
A model study for the coexistence of the spin density wave and superconductivity is presented. With reference to the recent angle resolved photo emmission experimental data in high…
Coexistence of Band Jahn Teller Distortion and superconductivity in correlated systems
Haranath Ghosh, Manidipa Mitra, S. N. Behera +1
The co-existence of band Jahn-Teller (BJT) effect with superconductivity (SC) is studied for correlated systems, with orbitally degenerate bands using a simple model. The Hubbard m…
