Soft-mode nonlinearities away from ferroelectric phase transition
Payel Shee, Ipek Efe, Jingwen Li +3
The paper investigates how electronic polarizability and local-field effects influence the soft optical phonon mode in paraelectric SrTiO₃, using linear and two‑dimensional teraher…
Polarizing ultrathin ferroelectric BaTiO3 films through interfacial layer polarization
Ipek Efe, Edith Simmen, Tobias Goldenberger +3
An important requirement for the integration of ferroelectric thin films into devices is deterministic control of the polarization state in films of only a few unit cells in thickn…
Manipulating ferroelectricity without electrical bias: A perspective
Bixin Yan, Valentine Gillioz, Ipek Efe +1
Ferroelectric materials are established candidates for beyond complementary metal-oxide-semiconductor technology, owing to their non-volatile spontaneous electrical polarization. T…
Nanoscale electrostatic control in ferroelectric thin films through lattice chemistry
Ipek Efe, Alexander Vogel, William S. Huxter +7
Nanoscale electrostatic control of oxide interfaces enables physical phenomena and exotic functionalities beyond the realm of the bulk material. In technologically-relevant ferroel…
