  • Publication number: 20100260033
    Abstract: For a probe based data storage (PDS) device a ferroelectric film stack may be used as a media to store data bits by polarizing areas of the film as either an up domain or a down domain to represent bits. However a built-in-bias field (BBF) may create domain retention problems. By growing the ferroelectric films with stress and composition gradients this may generate polarization gradients which reduce the bias field. Thus, the retention (or imprint) may be improved with minimized BBF.
