Novel approach to advanced electronics, data storage with ferroelectricity

Phys.org   October 16, 2023 Ferroelectrics possess a spontaneous polarization that is switchable by an electric field and is critical for the development of low energy nanoelectronics and neuromorphic applications. However, the realization of switchable polarization in metal oxides with simpler structures has been a major challenge. An international team of researchers (Australia, India) demonstrated the presence of robust switchable polarization at the level of a single nanocrystalline in magnesium-doped zinc oxide thin films with polar wurtzite crystal structures. Voltage control of the polarization and the coupled electronic transport behavior revealed a giant resistance change of approximately 10000% . Time- and […]
