Abstract: Epitaxial GeSn (epi-GeSn) shows the capability to form ferroelectric capacitors (FeCAPs) with a higher remanent polarization (Pr) than epi-Ge. With the interface engineering by a high-k AlON, the reliability of the epi-GeSn-based FeCAPs is enhanced.… read more here.

Abstract: We have fabricated and electrically characterized at the wafer scale tens of metal-ferroelectric (HfZrO)-semiconductor capacitors and metal-graphene monolayer-ferroelectric (HfZrO)-semiconductor capacitors with the same top electrode dimensions. We have found that the memory windows of the… read more here.

DOI: 10.2528/pierl17111704
Abstract: An approach to separate the metallic and dielectric losses in ferroelectric capacitors in all range of tuning under control dc voltages (Udc) is considered. The procedure is based on measurements of the dc voltage dependencies… read more here.
