Hi, I want to understand the concept of piezoelectricity in Espresso, I have some doubts,
Is it necessary that in order to observe the phenomenon in direct manner (ie application of strain to get polarization), i need to create vaccum in the direction of polarization? or i can work with periordic systems, and observe polarization.? With respect to the same, if i want to see the effect of field on length dimension of input geometry, I have to proceed with applying vaccum in that direction.? Is my understanding of the approach incorrect ? can anyone help me understand it better. -- Regards, Swapnil Chandratre Graduate Student Dept. of Mechanical Engineering, University of Houston, Houston, TX (M)-713-294-9546 -------------- next part -------------- An HTML attachment was scrubbed...
