Platform for the Accelerated Realization, Analysis, & Discovery of Interface Materials

An NSF Materials Innovation Platform

PARADIM researchers seek to advance the fundamental understanding of oxide-based hetero-interfaces with a range of two-dimensional (2D) material systems including oxides, chalcogenides and graphene. Fabricating interfaces and heterostructures between complex oxides and 2D materials allows for the creation of atomically-precise “active substrates” that can have novel electronic and magnetic functionality, such as ferroelectricity, ferromagnetism, or superconductivity. Creating interface materials with designed properties opens up untold degrees of freedom that may result in transformational evolutions in next generation electronics.

Shown in the center is an optical floating zone furnace

Shown in the center is an optical floating zone furnace used to synthesize new materials together with images of it being used to grow single crystals of Pr2Zr2O7 (left in blue) and Yb2Ti2O7 (right in green). The resulting single crystals are several millimeters in diameter and several centimeters long. In the background is a high-resolution scanning transmission electron micrograph of an artificial material consisting of seven monolayers of LuFeO3 followed by one monolayer of LuFe2O4. The brightest dots correspond to lutetium atoms. The less intense dots correspond to iron atoms
