First-principles study on lattice instabilities and structural phase transitions in Ba doped La2CuO4

Synthesis and Exploring structural, magnetic, morphology and optical properties of La2−xAlxCuO4 (0 ≤ x ≤ 0.25) perovskite nanoparticles by microwave-assisted combustion method

“…The La 2 CuO 4 nanoparticles were synthesized using a chemical and physical techniques such as hydrothermal [14], combustion [15], sol-gel [16], solid state [17] and co-precipitation [18] techniques. Velasquez et al Synthesized La 2 CuO 4 using glycine and used it to convert glycerol to hydroxyacetone using the self-combustion method [19][20].…”

Role of Sr doping and external strain on relieving bottleneck of oxygen diffusion in La2−xSrxCuO4−δ

“…From our electronic structure analysis, we found that the contrasting change in the formation energy by Sr doping and external strain is originated from the different localization natures of electron carrier from both types of oxygen vacancies.Oxygen vacancies in complex oxides drastically changes the electronic properties of them. One of the most studied examples is the superconducting critical temperature of La 2 CuO 4 1-19 , for which both electron and hole doping have been achieved in conjunction with cation substitutions such as Ce 1 , Ca 2-6 , Sr 7-12 and Ba [13][14][15][16][17][18][19] . Meanwhile, the oxygen stoichiometry in La 2 CuO 4 can be reversibly controlled without degradation of the crystallinity 20 .…”
