27 Oct 2005 | | Journal: | J. Chem. Phys. 124, 104703 (2006) | | Subject: | Mesoscopic Systems and Quantum Hall Effect | | Abstract: | We demonstrate that the single-channel transmission in the resonance tunneling regime exhibits self-similarity as a function of the nanowire length and the energy of incident electrons. The self-similarity is used to design the nonlinear transformation of the nanowire length and energy which, on the basis of known values of transmission for a certain region on the energy-length plane, yields transmissions for other regions on this plane. Test calculations with a one-dimensional tight-binding model illustrate the described transformations. Density function theory based transport calculations of Na atomic wires confirm the existence of the self-similarity in the transmission. | | Source: | arXiv, cond-mat/0510765 | | Services: | Forum | Review | PDF | Favorites | |
