- *Abstract
-
Recent trends in electronics allude to a human-centric computing paradigm where high performance electronic devices will have to work on unusual surfaces with unconventional form factors. A key component of such a computer is a memory device for which Ferroelectric (FE) materials have long been considered as an ideal candidate. However, integration of the best quality FE films on flexible substrates has remained a daunting challenge, severely limiting the performance that can be achieved in these devices.
Motivated by this challenge, UC Berkeley researchers have developed a pathway for integrating epitaxial quality, FE memory devices onto flexible substrates by providing an epitaxially grown ferroelectric stack on a flexible substrate that exhibits high performance characteristics such as high polarization, fast switching and low power operation for memory devices.
