Tbit/inch(2) ferroelectric data storage based on scanning nonlinear dielectric microscopy

摘要

Nanosized inverted domain dots in ferroelectric materials have potential applications in ultrahigh-density rewritable data storage systems. Here, a data storage system based on scanning nonlinear dielectric microscopy and thin films of ferroelectric single-crystal lithium tantalite is presented. Through domain engineering, nanosized inverted domain dots have been successfully formed at a data density of 1.50 Tbit/in.(2). (C) 2002 American Institute of Physics. References: 10
