Structural and mechanical properties of La 1/3 NbO 3 and La 1/3 TaO 3 thin films prepared by chemical solution deposition

Second-order Jahn–Teller effect induced high-temperature ferroelectricity in two-dimensional NbO2X (X = I, Br)

“…, the T c of BaTiO 3 , PbTiO 3 , PbZr 1− x Ti x O 3 , and La 1/3 NbO 3 is 393, 763, 659, and 473 K respectively). 11–14 This inspires us to search for high-temperature ferroelectric materials with SOJT-activated cations.…”

“…Interestingly, the Curie temperature T c of these compounds is far above room temperature (i.e., the T c of BaTiO 3 , PbTiO 3 , PbZr 1−x Ti x O 3 , and La 1/3 NbO 3 is 393, 763, 659, and 473 K respectively). [11][12][13][14] This inspires us to search for hightemperature ferroelectric materials with SOJT-activated cations.…”

“…However, only a few dozens of them have been conrmed by experiments. 13,14 The most intuitive strategy for designing new 2D ferroelectric materials is to use the structure of existing 2D ferroelectric materials in the databases as a prototype and then test different combinations of chemical elements. To date, only tens of prototypes, like CuInP 2 S 6 type, 15,16 SnTe type, 17,18 a-In 2 Se 3 type, 19,20 1T ′ -MoTe 2 type, 21,22 sliding ferroelectrics and so on, are proposed theoretically and experimentally.…”

Active La–Nb–O compounds for fast lithium-ion energy storage

“…La-Nb-O compounds mainly contain La 3 NbO 7 , LaNbO 4 , LaNb 3 O 9 , LaNb 5 O 14 , La 2 Nb 12 O 33 , etc. [11,12] [13][14][15]. However, among niobium oxide compounds, the NbO 4 tetrahedron is rarely found, because the large Nb 5+ atom cannot fit into the oxygen-anion tetrahedron.…”
