“…In addition to the unique piezoelectric properties, some remarkable photonic properties have also been detected in some 2D nanomaterials. For example, discrete solitons have been observed in the graphene-based nanomaterials recently [136], which indicates that 2D nanomaterials can be promising material candidates for the innovative design of nextgeneration optoelectronics [136][137][138]. Moreover, when the distinctive photonic, piezoelectric, and semiconductor properties of 2D nanomaterials are coupled, this will produce the novel piezophototronic effect in 2D nanomaterials.…”

The discovery of piezoelectricity in 2D nanomaterials represents a milestone towards embedding low-dimensional materials into future technologies. This article reviews recent progress in the characterization, properties evaluation, and applications of piezoelectricity of 2D piezoelectric nanomaterials (PNs). To begin, an introduction to the existing 2D PNs, which exhibit a wide range of atomic structures and configurations, is presented. The nanoscale measurements and associated experimental techniques as well as the atomic simulations of the piezoelectric properties of 2D PNs are then summarized. Some of the pertinent parameters, which govern the piezoelectric properties of 2D PNs, are discussed. Furthermore, our article concludes with some potential applications including piezotronics, piezophototronics, and energy harvesting of 2D PNs, which can open the doors to the innovative design of next-generation nanoelectronics and nanodevices. Finally, we highlight perspectives and challenges for the future development of 2D PNs.

“…These play a central role in a multitude of mechanical phenomena such as dislocation motion in crystals [11], ferroelectric phase transitions [12], structural collapse [13], transitions due to shape memory effects [14], transformational plasticity [15], and nanoscale structural mechanics [16]. Phase transition scenarios in which the effects of lattice dispersion are balanced by the nonlinear medium have been investigated theoretically; see, e.g., Refs.…”

Unidirectional Transition Waves in Bistable Lattices

et al. 2016

View full text Add to dashboard Cite

We present a model system for strongly nonlinear transition waves generated in a periodic lattice of bistable members connected by magnetic links. The asymmetry of the on-site energy wells created by the bistable members produces a mechanical diode that supports only unidirectional transition wave propagation with constant wave velocity. We theoretically justify the cause of the unidirectionality of the transition wave and confirm these predictions by experiments and simulations. We further identify how the wave velocity and profile are uniquely linked to the double-well energy landscape, which serves as a blueprint for transition wave control.

“…Non-or weakly dissipative models have been used to explain phenomena such as dislocation motion [1], ferromagnetic domain wall motion [2], proton mobility in hydrogen-bonded chains [3], rotation of DNA bases [4], chains of rotating pendula [5], or lattices of bistable buckled, elastic structures [6]. By contrast, diffusive or dissipative kinetics play an essential role in describing the physics of, e.g., ferroelectric domain switching [7], dynamics of CNT foams [8,9], magnetic flux propagation in Josephson junctions with tunneling losses [10], pulse propagation in cardiophysiology [11] and neurophysiology [12], sliding friction [13], chemical surface adsorption [14], underdamped commensurate phase transitions [15], or defect conductivity in superionic conductors [16]. Although numerous theoretical studies have been devoted to characterizing the motion of phase boundaries particularly in 1D periodic physical, chemical, or biological systems, see, e.g.…”

Universal energy transport law for dissipative and diffusive phase transitions

et al. 2016

View full text Add to dashboard Cite

We present a scaling law for the energy and speed of transition waves in dissipative and diffusive media. By considering uniform discrete lattices and continuous solids, we show that-for arbitrary highly nonlinear many-body interactions and multistable on-site potentials-the kinetic energy per density transported by a planar transition wave front always exhibits linear scaling with wave speed and the ratio of energy difference to interface mobility between the two phases. We confirm that the resulting linear superposition applies to highly nonlinear examples from particle to continuum mechanics.
