Plasmonics with two-dimensional conductors.
A wealth of effort in photonics has been dedicated to the study and engineering of surface plasmonic waves in the skin of three-dimensional bulk metals, owing largely to their trait of subwavelength confinement. Plasmonic waves in two-dimensional conductors, such as semiconductor heterojunction and graphene, contrast the surface plasmonic waves on bulk metals, as the former emerge at gigahertz ...
متن کاملTwo-electron elastic tunneling in low-dimensional conductors
We solve the Lippmann-Schwinger equation describing one-dimensional elastic scattering of preformed pairs ~e.g., bipolarons! off a short-range scattering center, and find the two-particle transmission through a thin potential barrier. While the pair transmission is smaller than the single-electron transmission in the strongcoupling limit, it is remarkably larger in the weak-coupling limit. We a...
متن کاملMolecular Conductors with Two-chain Orbitals
We investigate a theoretical model applicable to molecular conductors, such as TTP and M(dmit)2 salts [M=Ni, Pd, Pt], whose charge carriers orig inate from two kinds of molecular orbitals. The model Hamiltonian consists of two independent Hubbard chains. The degree of charge transfer between the two chains is calculated. The results qualitatively agree with some experimental data.
متن کاملDimensional crossover and metal-insulator transition in quasi-two-dimensional disordered conductors
We study the metal-insulator transition (MIT) in weakly coupled disordered planes on the basis of a Non-Linear Sigma Model (NLσM). Using two different methods, a renormalization group (RG) approach and an auxiliary field method, we calculate the crossover length between a 2D regime at small length scales and a 3D regime at larger length scales. The 3D regime is described by an anisotropic 3D NL...
