The origin of insulating and non-ferromagnetic SrRuO3 monolayers
Zeeshan Ali, Zhen Wang, Andrew O'Hara +5
The electro-magnetic properties of ultrathin epitaxial ruthenate films have long been the subject of debate. Here we combine experimental with theoretical investigations of (SrTiO3…
Ionic control over ferroelectricity in 2D layered van der Waals capacitors
Sabine M. Neumayer, Mengwei Si, Junkang Li +7
The van der Waals layered material CuInP2S6 features interesting functional behavior, including the existence of four uniaxial polarization states, polarization reversal against th…
Unique features of polarization in ferroelectric ionic conductors
Andrew O'Hara, Nina Balke, Sokrates T. Pantelides
Ferroelectrics that are also ionic conductors offer possibilities for novel applications with high tunability, especially if the same atomic species causes both phenomena. In parti…
Nanoscale Phonon Spectroscopy Reveals Emergent Interface Vibrational Structure of Superlattices
Eric R. Hoglund, De-Liang Bao, Andrew O'Hara +16
As the length-scales of materials decrease, heterogeneities associated with interfaces approach the importance of the surrounding materials. Emergent electronic and magnetic interf…
