Properties of CeO2 and CeO2−x films Part II. High temperature properties

Change in magnetic properties induced by swift heavy ion irradiation in CeO2

“…6. It is known that oxygen vacancies in CeO 2 contribute to the increase in their lattice constant [9] because of the mutual repulsion of Ce cations near oxygen vacancies. The experimental result in Fig.…”

Pulsed-laser deposition of textured cerium oxide thin films on glass substrates at room temperature

“…Thin films of CeO 2 are of interest for various electronic and optical applications, such as silicon-on-insulator structures, miniaturized stable capacitors, oxygen sensors, buffer layers for high-temperature superconductor films, and optical coatings [1][2][3][4][5][6][7]. CeO 2 is an ionic metal oxide with a high melting point (2600°C) having remarkable chemical stability and electrical insulation.…”

Volatile CeIII Hexafluoroacetylacetonate Glyme Adducts as Promising Precursors for the MOCVD of CeO2 Thin Films

“…CeO 2 is a potential candidate for use in various technologies due to its insulating properties, [1] remarkable chemical stability, [2,3] and its interesting optical properties. [4] In addition, the large dielectric constant renders this material of potential use for application in smalldimension, stable, storage capacitors in dynamic random access memory (DRAM) devices.…”

“…There are two categories of cerium b-diketonate precursors, with the cerium ion in either 3+ or 4+ oxidation states. The precursors initially proposed were the tetrakis(2,2,6,6-tetramethyl-3,5-heptanedionato)cerium(IV) (Ce(tmhd) 4 ), tetrakis (6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionato)cerium(IV) (Ce(fod) 4 ), or Ce(fod) 3 . Among them, Ce(tmhd) 4 has been widely studied, even though it suffers drawbacks such as thermal decomposition and surface passivation.…”

“…Among them, Ce(tmhd) 4 has been widely studied, even though it suffers drawbacks such as thermal decomposition and surface passivation. [26] Similarly, Ce(fod) 4 and Ce(fod) 3 have serious problems associated with either sintering and thermal decomposition, [23] and/or with an unpredictable synthesis, and instability upon heating. [28] Given this situation, low melting temperature or liquid cerium precursors are highly desirable.…”
