Abstract:
The charge transport mechanism in thin amorphous and ferroelectric Hf0.50.5Zr0.50.5O22 films has been studied. It has been shown that the transport mechanism in studied materials does not depend on the crystal phase and is phonon-assisted tunneling between traps. The comparison of the experimental current-voltage characteristics of TiN/Hf0.50.5Zr0.50.5O22/Pt structures with the calculated ones provides the trap parameters: thermal energy of 1.251.25 eV and the optical energy of 2.52.5 eV. The trap concentration has been estimated as ∼1019−1020∼1019−1020 cm−3−3.
