Fundamentals of flexoelectricity in solids.
The flexoelectric effect is the response of electric polarization to a mechanical strain gradient. It can be viewed as a higher-order effect with respect to piezoelectricity, which is the response of polarization to strain itself. However, at the nanoscale, where large strain gradients are expected, the flexoelectric effect becomes appreciable. Besides, in contrast to the piezoelectric effect, ...
متن کاملFlexoelectricity in soft materials and biological membranes
Flexoelectricity and the concomitant emergence of electromechanical size-effects at the nanoscale have been recently exploited to propose tantalizing concepts such as the creation of “apparently piezoelectric” materials without piezoelectric materials, e.g. graphene, emergence of “giant” piezoelectricity at the nanoscale, enhanced energy harvesting, among others. The aforementioned developments...
متن کاملConformational flexoelectricity in nematic liquid crystals
2014 Using the direct flexoelectric effect in an hybrid (homeotropic-planar) nematic cell, we have measured the bulk flexoelectric coefficient e* for two cyanobiphenyl compounds, 8CB and 8OCB. For 8CB, the flexo coefficient is comparable in sign and magnitude with that of MBBA, i.e. e* ~ + 10-4 cgs. 8OCB presents an anomalously large and negative e* ~ 5 x 10-4 cgs. The small influence of the cy...
متن کاملFlexoelectricity: A Perspective on an Unusual Electromechanical Coupling
The ability of certain materials to convert electrical stimuli into mechanical deformation, and vice versa, is a prized property. Not surprisingly, applications of such so-called piezoelectric materials are broad—ranging from energy harvesting to self-powered sensors. In this perspective, written in the form of question-answers, we highlight a relatively understudied electromechanical coupling ...
متن کاملAnomalous nonlinear photoresponse in a InGaNÕGaN heterostructure
The nonlinear ~third to fourth order! as well as linear photoconductivity in a Gallium nitride/ Indium-Gallium nitride ~GaN/InGaN! heterostructure is investigated using femtosecond pulses in the infrared ~IR! and near ultraviolet ~UV!. An anomalous IR photoresponse is explained by a four level model for the GaN region including defect density fluctuations and nonlinear carrier transport phenome...
