Influence of piezoelectricity on the photorefractive effect
We demonstrate that the spatially modulated electric field that is associated with a photorefractive grating generates stress and strain components with symmetries that are different from those induced by a uniform electric field. Therefore, because of piezoelectricity and the elasto-optic effect, the symmetries of the effective dielectric and electro-optic constants to be used to describe the ...
متن کاملERP Old-New effect 1 Running head: THE ERP OLD-NEW EFFECT IN SHORT-TERM MEMORY Characterizing the ERP Old-New effect in a short-term memory task
The early and late components of the event-related potential (ERP) Old-New effect are well characterized with respect to long-term memory, and have been associated with processes of familiarity and recollection, respectively. Now, using a short-term memory paradigm with verbal and non-verbal stimuli we explored the way that these two components respond to variation in recency and stimulus type....
متن کاملEffect of water on piezoelectricity in bone and collagen.
Interferometric measurements of bovine bone and tendon show that the values of the piezoelectric strain constant d14 decrease with hydration from the dry values of 0.2 X 10(-14) and 2.0 X 10(-14) m/V, respectively. The decrease of piezoelectricity in tendon is exponential with a characteristic hydration of 7% by weight from which an upper limit of the average molecular weight of the responsible...
متن کاملGeometric Currents in Piezoelectricity
As a simple model for piezoelectricity we consider a gas of infinitely many non-interacting electrons subject to a slowly timedependent periodic potential. We show that in the adiabatic limit the macroscopic current is determined by the geometry of the Bloch bundle. As a consequence we obtain the King-Smith and Vanderbilt formula up to errors smaller than any power of the adiabatic parameter. v...
متن کاملCritical piezoelectricity in percolation
2014 We study the behaviour of piezoelectricity in highly heterogeneous media. The piezoelectric effect introduces a coupling between electrical and mechanical properties, which have separately different scaling behaviours. Its study therefore constitutes a priori an interesting question. This problem is also suggested by the recent development of low-density, porous piezoelectric ceramics whic...
