Pure chromium nitride thin films were deposited on a ZrO2 layer buffered oxide ceramic substrate by the chemical solution deposition method. The effects of annealing temperature on their microstruc...

Epitaxial thin films of perovskite BaSn1–xSbxO3−δ are fabricated by a simple chemical solution deposition method, and the relationship among the processing, the microstructure, and the optoelectronic property is systematically investigated. The process of multiple annealing combined with the postannealing under nitrogen ambient is the optimal procedure to fabricate high quality BaSnO3−δ thin films. Sb doping in Sn sites facilitates the epitaxial growth of the BaSnO3−δ grains. The Hall results show that with increasing Sb doping content the carrier density and the carrier mobility are enhanced and decreased, respectively, resulting in the highest room-temperature electrical conductivity of 260 S/cm in the BaSn0.91Sb0.09O3−δ thin film. It is confirmed that the ionized Sb5+ and oxygen vacancies are the main scattering sources for carrier transport in BaSn1–xSbxO3−δ thin films. The results will provide guidance for synthesis of BaSnO3−δ-based and other donor-doped perovskite transparent conducting large-area ...

The phase-controlled synthesis of metallic and ambient-stable 2D MX2 (M is Mo or W; X is S) with 1T octahedral coordination will endow these materials with superior performance compared with their semiconducting 2H coordination counterparts. We report a clean and facile route to prepare 1T-MoS2 and 1T-WS2 through hydrothermal processing under high magnetic fields. We reveal that the as-synthesized 1T-MoS2 and 1T-WS2 are ambient-stable for more than 1 year. Electrochemical measurements show that 1T-MoS2 performs much better than 2H-MoS2 as the anode for sodium ion batteries. These results can provide a clean and facile method to prepare ambient-stable 1T-phase MX2.

Epitaxial-stabilized (110) NdNiO3−δ films were first realized successfully by chemical solution deposition under ambient oxygen annealing. Cross-section transmission electronic microscopy observati...
