Roadmap on ferroelectric hafnia- and zirconia-based materials and devices
Silva, José Pedro Basto; Alcala, Ruben; Avci, Uygar E.; Barrett, Nick; Bégon-Lours, Laura; Borg, Mattias; Byun, Seungyong; Chang, Sou ChiFerroelectric hafnium and zirconium oxides have undergone rapid scientific development over the last decade, pushing them to the forefront of ultralow-power electronic systems. Maximizing the potential application in memory devices or supercapacitors of these materials requires a combined effort by the scientific community to address technical limitations, which still hinder their application. Besides their fav...
Wake-up free ferroelectric rhombohedral phase in epitaxially strained ZrO2 thin...
Silva, José Pedro Basto; Negrea, Raluca F.; Istrate, Marian C.; Dutta, Sangita; Aramberri, Hugo; Íñiguez, Jorge; Figueiras, Fábio G.; Ghica, CorneliuZirconia- and hafnia-based thin films have attracted tremendous attention in the past decade because of their unexpected ferroelectric behavior at the nanoscale, which enables the downscaling of ferroelectric devices. The present work reports an unprecedented ferroelectric rhombohedral phase of ZrO2 that can be achieved in thin films grown directly on (111)-Nb:SrTiO3 substrates by ion-beam sputtering. Structura...
