Rigidity of dipolar coupled H2O molecular network in external electric field

Popis výsledku v původním jazyce

We have performed the first study of the effect of an external electric field on the quantum paraelectric state of the electric dipolar lattice of polar water molecules confined within nano-sized cages of beryl crystal lattice. The permittivity is measured at frequencies 1 Hz-1 MHz in the temperature interval 10-300 K both in zero and 7 kV/cm external field. For comparison, we measure dielectric response of KTaO3. In KTaO3, the application of electric field of several kV/cm leads to a diffuse phase transition. In beryl, however, a bias electric field of up to 7 kV/cm has no effect on the dielectric response of the water molecules network. This result is confirmed by Monte Carlo simulations. We attribute the enhanced rigidity of the water dipolar subsystem to the strong long-range dipole-dipole interaction between separate H2O molecules. The field that could affect the polarization state is estimated to be 100 kV/cm.
