Dr. Clarke's research focuses on the physics of novel epitaxial materials, including magnetic and ferroelectric thin-film structures. Questions of interest relate to the unusual properties of thin-film materials that are increasingly important for microelectronics applications. Ongoing research projects include the following: Ferroelectric heterostructures for their extraordinary dielectric behavior and symmetry-breaking structural transitions; Magnetic nanostructure studies aimed at understanding the link between structural and magnetic anisotropy in materials for high-density recording applications; and diamond-like boron nitride films for field emission and neutron detection applications. This work is in collaboration with the Space Physics Research Lab.
