Finite-size corrections of defect energy levels involving ionic polarization

Alfredo Pasquarello, Stefano Falletta, Julia Anna Wiktor

We develop a scheme for finite-size corrections of vertical transition energies and single-particle energy levels involving defect states with built-in ionic polarization in supercell calculations. The method accounts on an equal footing for the screening ...

Hybrid Metal-Dielectric Metasurfaces for Refractive Index Sensing

Olivier Martin, Hatice Altug, Christian Santschi, Debdatta Ray, Dordaneh Etezadi

Hybrid metal-dielectric nanostructures have recently gained prominence because they combine strong field enhancement of plasmonic metals and the several low-loss radiation channels of dielectric resonators, which are qualities pertaining to the best of bot ...

Dynamic piezoelectric response of relaxor single crystal under electrically driven inter-ferroelectric phase transformations

Dragan Damjanovic

In this work, we demonstrate that xPb(In1/2Nb1/2)O3-(1-x-y)Pb(Mg1/3Nb2/3)O3-yPbTiO3 [110]-poled domain-engineered relaxor single crystals can be dynamically and reversibly driven through a ferroelectric–ferroelectric phase transition exhibiting a highly en ...

Quantitative Mapping of the Charge Density in a Monolayer of MoS2 at Atomic Resolution by Off-Axis Electron Holography

Andras Kis, Dumitru Dumcenco, Dmitry Ovchinnikov

The electric potential, electric field, and charge density of a monolayer of MoS2 have been quantitatively measured at atomic-scale resolution. This has been performed by off-axis electron holography using a double aberration-corrected transmission electro ...

Correlated states in twisted double bilayer graphene

Oleg Yazyev, Quansheng Wu, Cheng Shen, Na Li, Jian Tang, Rong Yang

Electron-electron interactions play an important role in graphene and related systems and can induce exotic quantum states, especially in a stacked bilayer with a small twist angle(1-7). For bilayer graphene where the two layers are twisted by the 'magic a ...

Improve the Model Stability of Dam's Displacement Prediction Using a Numerical-Statistical Combined Model

Zhenzhu Meng, Yating Hu, Chenfei Shao

In most studies of dam's displacement prediction based on monitoring data, emphasis was given on improving the prediction accuracy, while the model stability was merely considered. This study proposed a numerical-statistical combined model which aims to im ...

Towards the material limit and field concentration smoothing in multilayer dielectric elastomer actuators

Yves Perriard, Yoan René Cyrille Civet, Jonathan André Jean-Marie Chavanne, Morgan Almanza

Performance of dielectric elastomer actuators is closely related to its breakdown field. On the other hand, to enhance the available energy, multilayer configuration is needed to increase the amount of active material. However, multilayer configuration suf ...
