Efficient calculation of the Green's function in scattering region for electron-transport simulations
Yoshiyuki Egami, Shigeru Tsukamoto, Tomoya Ono
We propose a first-principles method of efficiently evaluating electron-transport properties of very long systems. Implementing the recursive Green's function method and the shifte…

Magnetic orderings in Al nanowires suspended between electrodes
Tomoya Ono, Shigeru Tsukamoto, Kikuji Hirose
A theoretical analysis of a relation between atomic and spin-electronic structures for the ground state of single-row aluminum nanowires suspended between Al(001) electrodes is dem…
