Tunable ferroelectricity in artificial tri-layer superlattices comprised of non-ferroic components

K. Rogdakis, J. W. Seo, Z. Viskadourakis +7

Heterostructured material systems devoid of ferroic components are presumed not to display ordering associated with ferroelectricity. In heterostructures composed of transition met…

Ferroelectric Instability under Screened Coulomb Interactions

Yong Wang, Xiaohui Liu, J. D. Burton +2

We explore the effect of charge carrier doping on ferroelectricity using density functional calculations and phenomenological modeling. By considering a prototypical ferroelectric…

Time-dependent versus static quantum transport simulations beyond linear response

ChiYung Yam, Xiao Zheng, GuanHua Chen +3

To explore whether the density-functional theory non-equilibrium Green's function formalism (DFT-NEGF) provides a rigorous framework for quantum transport, we carried out time-depe…

Ferroelectric Dead Layer Driven by a Polar Interface

Y. Wang, M. K. Niranjan, K. Janicka +4

Based on first-principles and model calculations we investigate the effect of polar interfaces on the ferroelectric stability of thin-film ferroelectrics. As a representative model…

Atomistic simulations of self-trapped exciton formation in silicon nanostructures: The transition from quantum dots to nanowires

Y. Wang, R. Q. Zhang, Th. Frauenheim +1

Using an approximate time-dependent density functional theory method, we calculate the absorption and luminescence spectra for hydrogen passivated silicon nanoscale structures with…
