Reply to Comment on "Dynamical corrections to the DFT-LDA electron conductance in nanoscale systems"
Na Sai, Michael Zwolak, Giovanni Vignale +1
We reply to the comment by Jung, Bokes, and Godby (arXiv:0706.0140) on our paper Phys. Rev. Lett. 94, 186810 (2005). We show that the results in their comment should not be taken a…
Microscopic Current Dynamics in Nanoscale Junctions
Na Sai, Neil Bushong, Ryan Hatcher +1
So far transport properties of nanoscale contacts have been mostly studied within the static scattering approach. The electron dynamics and the transient behavior of current flow,…
Local electron heating in nanoscale conductors
Roberto D'Agosta, Na Sai, Massimiliano Di Ventra
The electron current density in nanoscale junctions is typically several orders of magnitude larger than the corresponding one in bulk electrodes. Consequently, the electron-electr…
Infrared Imaging of the Nanometer-Thick Accumulation Layer in Organic Field-Effect Transistors
Z. Q. Li, G. M. Wang, N. Sai +5
We report on infrared (IR) spectro-microscopy of the electronic excitations in nanometer-thick accumulation layers in FET devices based on poly(3-hexylthiophene). IR data allows us…
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…
