DESCRIPTION
Factors that Affect Phase Stability and Performance of Hafnium Oxide for Memory Applications
The proliferation of information technologies is leading to an energy crisis. New devices, algorithms, and materials are required to decrease humanity’s demand for energy in the computing sector. One important space is in the development of non-volatile, low energy memories. Ferroelectric hafnium oxide-based materials hold promise on this front owing to their chemical and processing compatibility with conventional semiconductors. However, the phase responsible for ferroelectricity does not exist on any phase diagram and requires the presence of one or more stabilizing mechanisms. This presentation will highlight the Ihlefeld Research Groups’ efforts to identify the phases present in hafnium oxide-based films, understand the mechanisms that stabilize the ferroelectric phase, which include substitutional ions, oxygen vacancies, finite crystal sizes, and mechanical stress, and then use these mechanisms to design a material with increased ferroelectric phase fraction, endurance, and data retention.
