Ferroelectricity in ultra-thin perovskite films
Na Sai, Alexie M. Kolpak, Andrew M. Rappe
We report studies of ferroelectricity in ultra-thin perovskite films with realistic electrodes. The results reveal stable ferroelectric states in thin films less than 10 Åthick wit…

Approach to steady state transport in nanoscale conductors
Neil Bushong, Na Sai, Massimiliano Di Ventra
We show, using a tight-binding model and time-dependent density-functional theory, that a quasi-steady state current can be established dynamically in a finite nanoscale junction w…

Dynamical corrections to the DFT-LDA electron conductance in nanoscale systems
Na Sai, Michael Zwolak, Giovanni Vignale +1
Using time-dependent current-density functional theory, we derive analytically the dynamical exchange-correlation correction to the DC conductance of nanoscale junctions. The corre…
