TL;DR: The requirements and development of high-k dielectric films for application in storage cells of future generation flash and dynamic random access memory (DRAM) devices are reviewed in this article.
Journal ArticleDOI
Electric field cycling behavior of ferroelectric hafnium oxide.
TL;DR: A new, analog-like split-up effect of switching peaks by field cycling is discovered and is explained by a network model based on memcapacitive behavior as a result of defect redistribution.
Journal ArticleDOI
Optimized Synthesis of the Elusive ε-Fe2O3 Phase via Sol−Gel Chemistry
Mihaela Popovici,Martí Gich,Daniel Nižňanský,Anna Roig,Cecilia Savii,Lluís Casas,Elies Molins,Karel Zaveta,Corina Enache,Jordi Sort,Sophie de Brion,and Gerard Chouteau,J Nogués +12 more
TL;DR: In this article, the e-Fe2O3 nanoparticles embedded in a SiO2 matrix have been synthesized by sol−gel chemistry and high temperature heat treatments, and they are stable up to ∼1600 K.
Journal ArticleDOI
Large coercivity and low-temperature magnetic reorientation in ε‐Fe2O3 nanoparticles
M. Gich,Anna Roig,Carlos Frontera,Elies Molins,Jordi Sort,Mihaela Popovici,Gérard Chouteau,D. Martín y Marero,J Nogués +8 more
TL;DR: In this paper, a large coercive field, HC=20kOe, is obtained at room temperature in e−Fe2O3 nanoparticles embedded in a silica matrix, produced by sol-gel chemistry.
