The dielectric constant ε and the threshold electric field E T for the onset of charge-density-wave conduction are investigated within the phenomenological model proposed by Tua and Zawadowski for the strong pinning regime. The static dielectric constant ε (E) in a bias electric field E is ...

Absorption at resonance and tunable resonant frequency can be expected due to the electric-field-tunable dielectric constant of BST. Moreover, some interesting resonant-mode jumping phe- nomena are observed in this MM, accompanied by remarkable frequency shift. Thus, this new mechanism shines some ...
The temperature dependence of the dielectric constant is studied under some fixed electric fields for the smectic G- (tilted-) smectic A (orthogonal) transition of the ferroelectric liquid crystal of compound A6. For this study, a mean field model with the quadrupole-quadrupole interactions is ...
Applied field dependence of static dielectric constant, and also dc bias field dependence of high frequency dielectric constant from 1 MHz to 100 MHz are measured in the helicoidal smectic C phase of ferroelectric liquid crystal (+)DOBAMBC.doi:10.1080/00150198408237869...

The effect of a constant external electric field on the transverse dielectric constant of a semiconductor is calculated. The field produces a sharp decrease in the dielectric constant close to the threshold for an interband transition. Above the edge, the behavior is oscillatory. Numerical results ...
