piezoelectric tensor मीनिंग इन हिंदी

If the piezoelectric tensor is considered to be that of the tetragonal crystal system ( that of BaTiO 3 ) then it is
Take as an example, the " d 33 " piezoelectric tensor coefficient of BaTiO 3, it has a value of 85.6 nm, a minute cantilever displacement even for the high precision of AFM deflection detection.
Among the tetrahedrally bonded semiconductors, it has been stated that ZnO has the highest piezoelectric tensor, or at least one comparable to that of GaN and AlN . This property makes it a technologically important material for many piezoelectrical applications, which require a large electromechanical coupling.
Consider that a static or DC voltage applied to a piezoelectric surface will produce a displacement but as applied fields are quite low and the piezoelectric tensor coefficients are relatively small then the physical displacement will also be small such that it is below the level of possible detection of the system.
