NRL-Developed Ferroelectric Heterostructures Could Aid Future DoD Sensing Missions

A team of Naval Research Laboratory scientists has conducted a study on monolayer ferroelectric hybrid structures that may lead to the development of materials that work to support Defense Department information processing and sensing missions.

NRL said Tuesday the researchers demonstrated the capacity of polarization domains from ferroelectric material lead zirconium titanate to spatially control the intensity and spectral composition of the photoluminescence from a single monolayer of tungsten disulphide.

The lab added the results from the study can help DoD develop low-power electronics, non-volatile optical memory and quantum computational technologies.

“Fabricating these hybrid 2D/3D ferroelectric heterostructures enables one to purposefully design and modulate adjacent populations of trions and neutral excitons, creating lateral domains in any geometry of choice,” said Berend Jonker, an NRL senior scientist and principal investigator of the study.
