Abstract

During this PhD project the student will grow and characterize the electronic structure of (anti)ferroelectric materials BiFeO3 , BaTiO3 and HfO2 , and use the electric polarization of these films to control the spin state of 2D molecular mono- layers. The ferroelectric systems will be fabricate by pulsed laser deposition and molecular beam epitaxy, and fully characterized for their structural, electronic and dielectric properties. The electric polarization of these films will be controlled at microscopic range using both piezoforce response and scanning tunneling microscopies (PFM and STM). (AU)
