The energy landscape of silicon systems and its description by force fields, tight binding schemes, density functional methods and Quantum Monte Carlo methods
S. Alireza Ghasemi, Maximilian Amsler, Richard G. Hennig +7
The accuracy of the energy landscape of silicon systems obtained from various density functional methods, a tight binding scheme and force fields is studied. Quantum Monte Carlo re…
Efficient implementation of the nonequilibrium Green function method for electronic transport calculations
Taisuke Ozaki, Kengo Nishio, Hiori Kino
An efficient implementation of the nonequilibrium Green function (NEGF) method combined with the density functional theory (DFT) using localized pseudo-atomic orbitals (PAOs) is pr…
Dual Spin Filter Effect in a Zigzag Graphene Nanoribbon
Taisuke Ozaki, Kengo Nishio, Hongming Weng +1
By first principle calculations, a dual spin filter effect under finite bias voltages is demonstrated in an antiferromagnetic junction of symmetric zigzag graphene nanoribbon (ZGNR…
