Ferroelectric Lithography of Multicomponent Nanostructures


  • We acknowledge the support from NSF grant DMR 96-32596 for facilities use, the Center for Science and Engineering of Nanoscale Systems (SENS) at the University of Pennsylvania, and the Department of Education. We have benefited from extensive discussions with John Vohs and S. Dunn.


A novel approach to fabricating multicomponent nanostructures is demonstrated. Atomic polarization in ferroelectric perovskites is manipulated to control electronic structure and local chemical reactivity (see Figure). Several paradigms for ferroelectric domain patterning are presented. Complex structures consisting of semiconductors, metals, and functional organic/biological molecules are produced.
