Insulating improper ferroelectric domain walls as robust barrier layer capacitors
Puntigam, Lukas; Schultheiss, Jan; Strinic, Ana; Yan, Zewu; Bourret, Edith; Altthaler, Markus; Keszmarki, Istvan; Evans, Donald; Meier, Dennis Gerhard; Krohns, Stephan (Peer reviewed; Journal article, 2021)We report the dielectric properties of improper ferroelectric hexagonal (h-)ErMnO3. From the bulk characterization, we observe a temperature and frequency range with two distinct relaxation-like features, leading to high ...
