Dielectric spectroscopy provides the short-time (AC) behaviour of insulators and semiconductors. It measures the electrical susceptibility of the material with intrinsic (ionic/dipolar/atomic/electronic) and proximity (grain-boundary/space-charge) contributions, which are affected by its structural/order-disorder/kinetic transitions, as well as by various relaxations/arrests. Our broadband impedance analyzer (NovoControl) enables probing the electrical response at extreme timescales, covering a rather wide range of conductivities and dielectric losses, alongwith the dispersive/non-activated behaviour.
