Electrodynamic Response and Stability of Molecular Crystals

Bohdan Schatschneider, Jian-Jie Liang, Anthony M. Reilly +3

We show that electrodynamic dipolar interactions, responsible for long-range fluctuations in matter, play a significant role in the stability of molecular crystals. Density functio…

Infrared conductivity of hole accumulation and depletion layers in (Ga,Mn)As- and (Ga,Be)As-based electric field-effect devices

B. C. Chapler, S. Mack, L. Ju +11

We have fabricated electric double-layer field-effect devices to electrostatically dope our active materials, either =0.015 GaMnAs or =3.2 Ga$_{1-x…

Reversible Control of Magnetic Interactions by Electric Field in a Single Phase Material

P. J. Ryan, J. -W. Kim, T. Birol +9

Intrinsic magnetoelectric coupling describes the interaction between magnetic and electric polarization through an inherent microscopic mechanism in a single phase material. This p…

Interplay between ferromagnetism, surface states, and quantum corrections in a magnetically doped topological insulator

Duming Zhang, Anthony Richardella, David W. Rench +12

The breaking of time-reversal symmetry by ferromagnetism is predicted to yield profound changes to the electronic surface states of a topological insulator. Here, we report on a co…

Conductivity of twin walls - surface junctions in ferroelastics: interplay of deformation potential, octahedral rotations, improper ferroelectricity and flexoelectric coupling

Eugene A. Eliseev, Anna N. Morozovska, Albina Y. Borisevich +4

Electronic and structural phenomena at the twin domain wall-surface junctions in the ferroelastic materials are analyzed. Carriers accumulation caused by the strain-induced band st…

Surface polar states and pyroelectricity in ferroelastics induced by flexo-roto field

A. N. Morozovska, E. A. Eliseev, S. V. Kalinin +2

Theoretical analysis based on the Landau-Ginzburg-Devonshire (LGD) theory is used to show that the joint action of flexoelectric effect and rotostriction leads to a large spontaneo…
