The study of Density Functional Theory for dispersion relation in Carbon nanotube with dielectric medium in a coupling mode
Abstract: The author shall study the excitation of Surface Plasmon and Phonon on cylindrical polar semiconducting material. The possibility of their interaction has been discussed with the help of dispersion relation for the dual mode of CNT by using inherent properties of the dielectric interface in dual mode. The phonon dispersion relation of the CNT is calculated by large supercells containing an isolated nanotube, Density functional Theory, and plane wave basis …

Theoretical Study of Surface Waves in Hexagonal Boron Nitride (hBN)
Abstract: Hexagonal boron nitride (hBN) is a wide bandgap semiconductor material in which Boron (B) and Nitrogen (N) atoms form hexagonal structure and has number of robust properties of technological importance. Boron nitride nanotubes (BNNTs) are very nice area of research in recent years. Its structure is similar to carbon nanotubes (CNTs) where carbon atoms are arranged in hexagon. hBN is also known as White Graphene. Various methods are employed to …

Behavior of Surface Polaritons on Cylindrical Semiconducting Materials at Nanoscale with Radius Dependence Frequency
Abstract: Surface plasmon resonance (SPR) is a physical property of the surface to investigate the important properties of optical behaviors for nanomaterial and biomaterial. It involves the excitation of electrons within a thin metal sheet by incident light at a specific angle, prompting them to propagate parallel to the surface. This sensitivity to external factors, such as changes in the refractive index of the surrounding medium due to molecular adsorption, underscores …

Theoretical Study of UV Surface Waves in AlAs and AlN
Abstract: Surface waves excited at the interface between polar semiconductor surface and a dielectric when electromagnetic waves of appropriate frequency are incident on it. When the incident electromagnetic energy in the form of photons is absorbed, these surface excitations generate. They are of different kinds such as plasmon, phonon, exciton etc. Plasmon is the quanta of valence electron oscillation; phonon is the quanta of lattice vibration and exciton is the quanta …
