## Description

- description: In view of the extensive use of hexagonal boron nitride (hBN) in 2D
    material electronics, it becomes important to refine its dielectric characterization
    in terms of low-field permittivity and high-field strength and conductivity up
    to the breakdown voltage. The present study aims at filling this gap using DC
    and RF transport in two Au-hBN-Au capacitor series of variable thickness in the
    10–100 nm range, made of large high-pressure, high-temperature (HPHT) crystals
    and a polymer derivative ceramics (PDC) crystals. We deduce an out-of-plane low
    field dielectric constant ε∥ = 3.4 ± 0.2 consistent with the theoretical prediction
    of Ohba et al., that narrows down the generally accepted window ε∥ = 3–4. The
    DC-current leakage at high-field is found to obey the Frenkel-Pool law for thermally-activated
    trap-assisted electron transport with a dynamic dielectric constant ε∥ ≃ 3.1 and
    a trap energy ΦB ≃ 1.3 eV, that is comparable with standard technologically relevant
    dielectrics.
