Non-adiabatic time-dependent density functional theory of the impurity resistivity of metals
V. U. Nazarov, G. Vignale, Y. -C. Chang
We make use of the time-dependent density functional theory to derive a new formally exact expression for the dc resistivity of metals with impurities. This expression takes fully…
On the relation between the scalar and tensor exchange-correlation kernels of the time-dependent density-functional theory
V. U. Nazarov, G. Vignale, Y. -C. Chang
The scalar and tensor exchange-correlation (xc) kernels are key ingredients of the time-dependent density functional theory and the time-dependent current d…
Exact dynamical exchange-correlation kernel of a weakly inhomogeneous electron gas
V. U. Nazarov, G. Vignale, Y. -C. Chang
The dynamical exchange-correlation kernel of a non-uniform electron gas is an essential input for the time-dependent density functional theory of electronic systems. The l…
Higher order contributions to Rashba and Dresselhaus effects
X. Cartoixa, L. -W. Wang, D. Z. -Y. Ting +1
We have developed a method to systematically compute the form of Rashba- and Dresselhaus-like contributions to the spin Hamiltonian of heterostructures to an arbitrary order in the…
Suppression of the D'yakonov-Perel' spin relaxation mechanism for all spin components in [111] zincblende quantum wells
X. Cartoixa, D. Z. -Y. Ting, Y. -C. Chang
We apply the D'yakonov-Perel' (DP) formalism to [111]-grown zincblende quantum wells (QWs) to compute the spin lifetimes of electrons in the two-dimensional electron gas. We accoun…
Spontaneous spin polarized tunneling current through a quantum dot array
David M. -T. Kuo, Y. -C. Chang
We show theoretically that a strongly spin-polarized current can be generated in semiconductors by taking advantage of the ferromagnetic phase of a quantum dot array (QDA). A Hubba…
