ORNL finding could help electronics industry enter new phase
Date:6/17/2009

ormation and read-write voltages, a key requirement for any viable memory technology," Kalinin said.

Numerous previous works have demonstrated defect-mediated memory, but defects cannot easily be predicted, controlled, analyzed or reduced in size, Maksymovych said. Ferroelectric switching, however, surpasses all of these limitations and will offer unprecedented functionality. The authors believe that using phase transitions such as ferroelectric switching to implement memory and computing is the real fundamental distinction of future information technologies.

Making this research possible is a one-of-a-kind instrument that can simultaneously measure conducting and polar properties of oxide materials with nanometer-scale spatial resolution under a controlled vacuum environment. The instrument was developed and built by Baddorf and colleagues at the Center for Nanophase Materials Sciences. The materials used for this study were grown and provided by collaborators at the University of California at Berkeley.
