Everything is made of something.

The ability to design, synthesize and measure materials with picometer resolution represents an emerging, final frontier in materials science.  Whereas the past two decades have seen remarkable advances in nanoscience and engineering, in which materials are designed and engineered at the 1-100 nm length scale via the control of clusters of atoms, we are now in an era of picoscale materials development, where picometer-scale distortions, including manipulation and control of subtle bond configurations between individual atoms, strongly modify functional behavior in the solid state.  This can result in materials having properties that do not exist in nature.  Picoscience offers the ultimate length scale to engineer materials, since distortions smaller than a single picometer become too small to alter macroscopic material properties.


Welcome to Ahn Lab

The research group focuses on the fabrication and the study of the physical properties of novel complex oxide materials using advanced growth and characterization techniques, including molecular beam epitaxy and synchrotron x-ray scattering techniques.  Current interests include the physics and technology of multifunctional oxides, nanofabrication and electronic writing using scanning probe microscopies, electronic control of complex order parameters in correlated oxides, and development of nonvolatile logic switches for post-CMOS computing paradigms.
