Crystallization and Texturing of SrxBa1–xNb2O6 Thin Films Prepared by Aqueous Solution Deposition─An In Situ X-ray Diffraction Study
Pedersen, Viviann Hole; Blichfeld, Anders Bank; Bakken, Kristine; Chernyshov, Dmitry; Grande, Tor; Einarsrud, Mari-Ann (Peer reviewed; Journal article, 2022)Aqueous chemical solution deposition (CSD) is an environmentally friendly and highly flexible fabrication route to prepare oxide thin films. Here, we present an aqueous CSD process for ferroelectric SrxBa1–xNb2O6 (SBN) ... -
Structures and Role of the Intermediate Phases on the Crystallization of BaTiO3 from an Aqueous Synthesis Route
Bakken, Kristine; Pedersen, Viviann Hole; Blichfeld, Anders Bank; Nylund, Inger-Emma; Tominaka, Satoshi; Ohara, Koji; Grande, Tor; Einarsrud, Mari-Ann (Peer reviewed; Journal article, 2021)Carbonate formation is a prevailing challenge in synthesis of BaTiO3, especially through wet chemical synthesis routes. In this work, we report the phase evolution during thermal annealing of an aqueous BaTiO3 precursor ... -
Thermal expansion of SrxBa1−xNb2O6 across and above the ferroelectric phase transition
Pedersen, Viviann Hole; Chavez Panduro, Elvia Anabela; Hua, Weicheng; Michaelsen, Marcus Grand; Chernyshov, Dmitry; Walker, Julian Bradley; Grande, Tor; Einarsrud, Mari-Ann (Peer reviewed; Journal article, 2024)Lead-free SrxBa1−xNb2O6(SBN) is of interest due to flexible chemistry, ferroelectric behavior, and electro-optic properties. The thermal expansion coefficient for SBN is reported only for compositions x = 0.35–0.59 and ...
