Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Energy harvesting from vibrations with a nonlinear oscillator [PDF]

, 2009
In this paper we present a nonlinear electromagnetic energy harvesting device that has a broadly resonant response. The nonlinearity is generated by a particular arrangement of magnets in conjunction with an iron-cored stator.

Comparison of Seismic Site Factor Models Based on Equivalent Linear and Nonlinear Analyses and Correction Factors for Updating Equivalent Linear Results for Charleston, South Carolina

Geosciences
In practice, site-specific one-dimensional (1D) seismic site response analyses are conducted to compute surface acceleration time histories considering shear wave velocity profile, modulus reduction, damping, and site-specific ground motions.

Time-domain constitutive model based on logarithmic skeleton curve and its application

Yantu gongcheng xuebao, 2020
The equivalent linearization method for seismic nonlinear response of soils will overestimate its high-and low-frequency nonlinear effects, and the plastic deformation of soils can not be reflected, especially for soft soil layer sites and thin ...

Electrically Induced Phase Transition and Synaptic Functionality in MoTe2/Graphene Memristors

Advanced Functional Materials, EarlyView.
An electrically induced reversible 2H ↔ 1T′ phase transition is demonstrated in a vertical Au/Ti/MoTe2/graphene memristor with a laterally contacted graphene electrode. Resistive switching proceeds through a compositionally invariant amorphous/2H ↔ amorphous/1T′ transformation, in which a self‐formed amorphous MoTe2 interfacial region is proposed to ...
